In+ersec+ion for Spatial People

We informed you a few times already about the upcoming FOSS4G-NA 2013 conference in Minneapolis in May 22-24, what's new is Slashgeo is going to be a proud media partner of the event!

Reminder: "FOSS4G brings together public and private-sector stakeholders, innovators and developers who are at the forefront of free and open source software for geospatial applications. FOSS4G-NA 2013 will offer a broad program to discuss and build tools to help solve some of the world’s most pressing problems and business needs. FOSS4G-NA 2013 follows on the success of the 2012 conference held in Washington, DC.  This regional event complements the larger FOSS4G International Conference, the leading global conference organized by OSGeo focusing on Free and Open Source Software for Geospatial."

We mentioned in January the upcoming FOSS4G-NA 2013 conference in Minneapolis May 22-24. Yesterday, the organizers announced the preliminary program and early bird registration deadline.

The keynote speakers according to the preliminary program pdf:

• "Eric Gundersen, CEO at MapBox. With names like USA Today and Foursquare leaving Google Maps in favor of MapBox, Eric will be discussing the business proposition and value of commercial open source geospatial. Hear why “giving away the code” does not mean giving away the farm.
• Bibiana McHugh, IT Manager of GIS and Location­Based Service, Portland TriMet. A true instigator, Bibiana started what became Google Transit. Her team has made nearly all TriMet data accessible for anyone to use and develop on. She will touch on aspects of making open source successful in government, working with the developer community and open data.
• Erek Dyskant, Sr. Analytics Engineer at Democratic National Committee. Regardless of your political affiliation, it is clear that the Obama Campaign must have done something right. Erek will provide a more technical discussion on how they used an open source geospatial stack to support the campaign and describe what drove the intentional choice of using open source.
• Paul Morin, Director of the NSF and NASA funded Polar Geospatial Center at the University of Minnesota. He makes maps for Wired, Scientific American and National Geographic and is co­author of “Exploring Geology” one of the best selling introductory geology textbooks. Morin contributed to David Attenborough’s Frozen Planet and is the US representative for geospatial data to the Antarctic Treaty System. His group of less than two dozen people are mapping both the Arctic and Antarctic at sub­meter resolution with a combination of open source and proprietary tools, and a lot of imagery."

The details of FOSS4G North America 2013 have been announced­. Everything is there, from registration, the call for presentations, the gala and the code sprint.

Amongst the keynotes they propose: "Eric Gundersen, CEO, MapBox.  With big names converting from Google Maps to MapBox (USA Today, Foursquare, etc.), Eric will be discussing the business proposition/value of open source geo.

Erek Dyskant, Sr. Analytics Engineer, Democratic National Committee. Whether you were happy or sad with the outcome of the recent election, they must have done something right!  Erek will talk about how open source solutions were used to empower tacticians with geospatial data, and describe what drove the intentional choice of using open source."

Last year, Slashgeo had the chance to be a media partner of the first FOSS4G-NA 2012.

Most, if not all, FOSS4G-NA 2012 talks are or will be freely available online, many with full video recording. The program schedule is available online.

Day 3

RadiantBlue - OMAR

• OMAR = Open Mapping ARchive
• About 20 people supporting and developing their open source software, another proof that this business model can work
• Web-based polished raster search user interface with a real fast data viewer
• Apparently easy to import data into OMAR

RadiantBlue - OSSIM

• Advanced C++ remote sensing and geospatial processing
• Started in 1998
• One of the founding projects of OSGeo
• Used in numerous commercial and government solutions

• Long history of government projects
• My main interest was in ossimPlanet, since we have our own in-house scientific virtual globe at MSC
• Along with the ossimPlanet tool, there's ImageLinker and OMAR that work together
• There's OSSIM Libraries
• Image chains for data processing, such as models, filters, combiners, with an excellent UI
• dynamic plugins

• ossimPlanet: virtual globe similar to Google Earth and NASA WorldWind (whatever happened to it), but... supports multiple platform, photogrammetric accuracy, native file access, WMS compliant
  • high performance 3D solution

• Demoed their tools

Skipped some talks that were mostly U.S.-specific

Panel on challenges in implementing FOSS4G software

• Integration with existing 'legacy' software such as SharePoint or Oracle can be a challenge
• Legal components of open source are not an issue. It's unlikely that open licenses will do a great deal of damages to projects and organizations
• Community is essential for the feedback loop in the open source software
• Security audits are the same for open source than for commercial software
• Panelists discussed their success stories

Panel on open source geo in federal IT

• More intimate relation with open source vendors than with proprietary vendors, particularly in regards to feature needs, development, etc
• Open source isn't entirely free, you need to put efforts
• OGC standards are much faster implemented in open source geo software than in proprietary ones
• Funding positions of Geospatial professionals on the long term can be a challenge at the federal level
• Investing in open source consulting vs employ a senior full time expert... sometimes the first option seems to be much more efficient
• Collaboration with the community requires energy, but it pays off over time
• The pertinence of having federal IT coordination in their investment in open geospatial software and access the impact of their investment on each other
• Challenge with reaching stakeholders of the federal gov which has interest in open source geo
  • At the Government of Canada we have the FCGEO (Federal Committee on Geomatics and Earth Observation) and GeoConnections, etc... there are some coordinating bodies and resources
• The best with open source geo is rapid updates and delivery mechanisms
• Expectations that the cloud will impact significantly how geospatial data is managed and stored at the federal level
• GeoCat Bridge, bridging ArcMap to open source SLD compatible software - just can't ignore past ArcMap investments

That's the second out of three summary entries on FOSS4G-NA 2012.

Reminder, here's my notes, stripped from content directly related to my employer. These notes intend to provide some level of information on components that I considered interesting or pertinent. Most, if not all, FOSS4G-NA 2012 talks are or will be freely available online, many with full video recording. The program schedule is available online.

Day 2

Mike Byrne FCC Wednesday plenary

• We don't make paper maps
• The importance of URLs
• Unintended consequences of data use are good
• Spatial data is not special... it's just columns in a database
  • I think I personally disagree with that statement; spatial data requires a datum and a projection and implies things like spatial topology and so on, so to me, these major distinctions makes it 'special' to some extent
• Need for low barrier to publish and low barrier to consume

Josh Berkus, PostgreSQL

• Large data collection with continuous processing and aggregation, firehose engineering
• Challenges:
  • volume of data, and volume grows over time
  • constant flow of data, 24/7, data collection component, it means no ETL
  • database size, lots of hardware, backups, redundancy, migration, etc... database growth, many components = many failures
  • component failures, all components fail, and data collection must meanwhile continue
• Data collection must be: continuous, parallel and fault-tolerant
• Don't use cutting edge technology, don't run components to capacity, do not do hot patching
• Little to no geospatial content in this talk

Ramsey - What's new in PostGIS 2.0

• Breaks some backward compatibility
• PostGIS uses a new serialization
• New WKT / WKB parser, Extended WKT vs OGC vs ISO
• New 3D functions
• 4D indexes, nD actually
• New 3D types and formats
• New shapefile loading GUI

• Raster
  • Raster support is there to enable analysis, not visualization, raster objects are very similar to vector objects in PostGIS
  • Many new raster functions
  • Raster Performance is still not great and sensitive to tile size, and function signatures can get very complex

• Integrated raster and vector analysis
• Indexed nearest neighbors, 2 million points, in 9 milliseconds... pretty fast

Tom Payne - OpenWebGlobe WebGL Globe

• Google Earth plugin competitor
• 100% JavaScript and WebGL
• SpiderGL.org and OpenWebGlobe.org
• Streaming lod terrain example on SpiderGL
• Spherical Mercator (more)
• Includes buildings, at various levels of quality to accommodate different use cases
• Data in the S3 cloud managed by TileCloud
• WebGL Navigation can't exactly mimic Desktop software
• It may need polishing, but it works well already
• VirtualGlobeBook.com for further reading
• WebGL is also an interest of the gaming industry so there's big pushing from them too
• No mobile browser supports WebGL yet

Bitner - Working with four dimensional flight track data

• Closer to the type of data I have to deal with than the CartoDB and PostGIS presentation
• XYZM (m = minutes)
• Smoothing track data
• Using R and PostgreSQL with the temporal extension on pgxn
• PostgreSQL 9.2 will have native time range data types
• R used for removing outlier data and helping the smoothing via statistics
• During spatial smoothing, must consider the time dimension otherwise it messes with speeds
• Displaying the 4D data
• Github OpenNOMS
• Using GeoExt and OpenLayers to display
• App.macnoise.com/flighttracker nice interactive map
• Rather technical presentation

Osti - Cloud-based open source tech to manage natural resources

• Opennrm.org
• Animated web maps, integrating a lot of sensor data, in the Californian delta for a fish and turbidity analysis
• Fully custom-made web page
• The GeoServer talk was probably more interesting

Davis - What's new in the JTS topology suite

• JTS started in 2001
• JTS and GEOS used by many may other software
  • GEOS 3.3.3 released at the beginning of the month
• There's a C# port and a JavaScript port JSTS
• What's new
  • Unary union
  • Delaunay triangulation, supports linear constraints
  • Voronoi diagram
  • Hausdorff distance: "measures how far two subsets of a metric space are from each other"
  • Densification, bounding envelopes
  • Single-sided spatial buffers
  • Magnify topology
• JTS comes with a GUI to test functions

• What's coming
  • Buffer performance improvements again
  • Fast distance computation
  • New algorithms such as concave hull, Bezier smoothing, point clustering, etc
• Future plans: computation in geodetic coordinate systems, improve performance is a constant quest, split packaging into core and algorithms, refactor geometry API to use interfaces
  • For JTS 2.0 since it will break the API backward compatibility
• That was an interesting but short 15 minutes talk... why not show more?

Klassen - Build your own cloud, open source approach to imagery storage

• 50 TB of data, essentially raster
• Their workflow is 'write once read many'
• Constraints: little staff time for maintenance, needs to scale, limit access to some datasets
• Image storage solution is OpenStack object storage aka Swift
  • Swift is optimized for long term storage
  • Why swift: no single point of failure, http/REST API, handles large objects over 5GB, security built-in
• They looked at alternatives such as raid servers, NoSQL such as BigCouch, distributed file systems and S3... but ended up using swift
• Proxy nodes: provides "public" URLs
• There's tradeoffs, including a significant learning curve
• Image catalog with a PostGIS backend
• Services viewers with MapServer and MapCache
• OpenAerialMap on Github.com/oam/oam

Ashton - cartography with TileMill, PostGIS and OpenStreetMap

• Presentation focused on digital map making; such as labels
• The import is part of the render
• Using group styles
• Abbreviations: prefix and suffix aren't that important, handling multiple languages abbreviations is a challenge
• Tens of types of 'spaces' in Unicode
• Features of MapBox Street in TileMill

Nathaniel - Watercolor maps using OpenStreetMap

• These maps were massively advertised in the past weeks
• maps.stamen.com... from stamen design
  • citytracking.org
• Different watercolor textures for each zoom level
• Used Mapnik and python processing
• Blurring things and adding noise, added inner glow
• They didn't render the whole world
  • They user tweets density to identify which areas to prerender at higher zoom levels
  • They also analyzed where people actually searched for watercolor maps

Matthew Davis - Incorporating open source mapping into mobile apps

• Excellent presentation
• Strategy options = native apps, web apps, hybrid apps
• Native apps: fast, mobile app feel, access to sensors, app store... but not cross-platform
  • iOS: 3 closed source maps APIs, none open source
  • Android: 4 mains options; Google Maps, osmdroid, Nutiteq, mapsforge... various tile sources, licensing, offline caching capabilities and vector support
• Web apps:
  • Good = cross platform, but... slower, limited access to sensor, levels of browser support, have to make it feel like a mobile app, no app store, etc...
  • HTML5/CSS3: app can run offline, local data storage, sensor support (GPS well supported, but others not (e.g. accelerometer)), varying degrees of implementation by browsers
  • Mobile frameworks
  • Open source mapping libraries: OpenLayers, Leaflet, Polymaps, Tile5, Modest Maps... things to consider: offline caching, touch gesture support, vector overlays, tile sources, size
• Hybrid apps: good = cross-platform, app store, sensor support, but... not as fast as native app, special attention to mobile app feel... main Hybrid apps solution is PhoneGap
• Detailed a case study & their experience

I was lucky to participate to the first FOSS4G-NA 2012 conference in Washington D.C. last week. Here's one of three entries in which I'll share my general notes, talk notes and links to other reviews of the conference. First, I want to acknowledge and thank the FOSS4G-NA 2012 organizers for this incredible conference and the complimentary pass as a media partner. There was also a recent official press release from OpenGeo wrapping up the conference. All entries related to FOSS4G-NA 2012 on Slashgeo should be found with a simple search.

Here's my general notes, stripped from content directly related to my employer. These notes intend to provide some level of information on components that I considered interesting or pertinent. Most, if not all, FOSS4G-NA 2012 talks are or will be freely available online, many with full video recording. The program schedule is available online.

General notes

• For Day 1 and 2, there were 3 concurrent tracks. For day 3, there was 2
• There was 'Ignite Spatial' presentations at the end of Day 2
• There was 350 attendees to FOSS4G-NA 2012
• Met and discussed with several colleagues and developers
• Next FOSS4G-NA 2013 will be in Minnesota

Day 1
 

Paul Ramsey Welcome Talk

• Discussed the history of open source
• Geeks and enthusiasm + tools + connectivity
• Paul reminded us that ArcGIS and Google Earth also use gdal, same for other pieces of open source geospatial software
• Open standards are embraced more quickly by open source software
• Exciting open source geospatial: Leaflet as a new OpenLayers competitor
• Proprietary software locks you in
• Open source software offers a lot of choice and it might be overwhelming, it appears 'simpler' with a single vendor solution
• Google is a FOSS4G-NA 2012 venue sponsor, and so is ESRI

Keith Barber, NGA

• NGA = National Geospatial Intelligence Agency (United States)
• GeoInt must be on-line and on-demand
• The 'pretty' component counts
• How does the users consume information and data? That matters a lot
• Big data, mobile computing, cloud computing, social networking
• Social networking is harnessing the power of already established associations

Kate Chapman, teaching QGIS and OpenStreetMap in Indonesia

• Hot: humanitarian OSM team, full details of their project here
• They did workshops in 9 regions
• Paper maps with no GIS involved
• They also used walkingpapers.org to input new data
• Using the Bing Maps satellite imagery in OSM, when available
• LearnOSM.org launched
• No street signs in small villages, only specific people know the street names
• GIS benefits are not obvious to people that don't know GIS
• Using OSM satellite imagery is much easier than buying a GPS and doing surveying
• On site Internet access is an issue, part of the solution is using 3G modems
• The OSM QGIS plugin is too hard to use in practice
• Goal was poverty mapping

Wickman - Emergency response performance analysis with open source geospatial

• Fire service departments
• First responders are the clients, and they're not always tech savvy
• E911 computer aided dispatch cad systems are almost systematically different one from another
• Cops vs fire fighters: they do not always get along happily
• Incident mapping
• Not all city GIS layers align correctly
• Using GeoKettle, PostGIS and MapServer and OpenLayers
• Showed their GeoKettle processing; seems relatively simple to use
• They'll be replacing MapServer with GeoServer, but didn't told us the reasons

De La Torre - CartoDB 1.0

• The 'Government Participation in Open Source' talk was cancelled
• New FOSS4G software, version 1.0 released last week
• Blazing fast drag and drop online mapping
• PostGIS 2 inside, with node.js and Mapnik
• Blazing fast geospatial queries directly on the online map
• Support importing OSM data
• Explained distinctions with Google Fusion Tables

MacWright - Beyond the Google Maps Paradigm

• Mapbox TileMill
• Everybody gets the same tiles on Google Maps and OpenLayers
• The design of today's maps is only possible because of the way we interact with it... There's less elements on maps because it's easy to zoom in and display more details
• OpenLayers weights 900k while Modest Maps API is 40k
• Google Maps got us halfway, TileMill halved it again
• He got a point: traditional geo technologies is evolving real fast, and not always pushed forward by geofolks

Herbert - FOSS, data delivery and discovery services - the Antarctic experience

• British Antarctic survey
• Gdal, PostGIS, GeoServer, OpenLayers, WMS, WFS
• From raw data acquisition to processing and distribution
• GeoRSS, kml, OGC services, jpeg 2000
• Using geonames.org
• Labeling is a challenge, SLD vendor options end up being critical
• Poor metadata and versioning
• They chose GeoNetwork Open Source for data discovery, with some cons
• Polarview.aq, map.arctic.ac.uk and a few more links

Hahn - Rendering the World

• Big world.... it requires a lot of storage and time to generate the tiles
• OpenStreetMap is 54 TB of storage
• Accepted wisdom: only render tiles on demand
• Render servers are slow, costly and stressful
• Pre-rendered tiles are fast, cheap and reliable
• The MBTiles format can store redundancy efficiently
• Tile storage
  • 17.2 billion tiles
  • Open ocean is 60% of World tiles, and it's a single blue tile
  • Solid land tiles are also redundant
  • 4 layers compositing
  • Human tiles is only about 1% of tiles
  • Instead of 10 TB, with removing the redundant tiles, it's 200 GB
• And for time
  • TileMill does all the tiles... With TileMill master, children skipping if redundant, pyramid approach... It mostly works at the moment
  • Instead of 200 days, it needs 4 days
• Still quite a lot of fine tuning to do
• This makes the whole World tile rendering possible

Panel Discussion on Gaps and Voids in open source geo technology

• User interfaces and user experience (UI and UX)
• We need to spend efforts to design interfaces
• Command line is powerful, but you lose plenty of potential users
• Goal is to engage non technical users
• User workflow
• Beyond the UI, there's the documentation too
• Who's the target customer of the software

• Innovation might not come from geoprofessionals if we aren't careful and think out of the box
• There's still not enough geoprofessionals for the industry needs
• It's about value and enabling users
• Investing in FOSS is like investing in fundamental science, it often pays off tremendously on the long term
• Cost of forking software is high and the value of a community is high
• Chose the open license that suits the context

• FOSS4G business models
• API vs download ? The answer is both
• Datasets don't tell you what's wrong with them... they should
• We still can't easily ask what-ifs questions with GIS... such as 'Whats the impact of changing this value or this other value'
• Need more cross projects collaboration

Schaub - OpenLayers: the rebirth of cool

• Moving to Github dramatically increased commits and contributors
• Talk focused on what's new 2.11 and upcoming 2.12
• Mobile devices support, this is major
• Html5 and CSS, tile transitions
• Many new keyboard controls via CSS
• Offline tile cache
• Canvas rendering
• UTFGrid interaction

• Improved UI/UX, including CSS styling
• Improved APIs
• Animations performance optimizations
• Tile queues with abortable tile requests
• Usability improvements, including documentation
• Custom built library for specific purposes
• Ongoing discussions about WebGL and Canvas 2D

Wadsworth - Raster Storage and Processing with MongoDB

• NoSQL, no joins
• Integrated spatial indexing functionality
• Fast, "web scale"
• Mongo huMongous
• Alternatives, CouchDB/ GeoCouch,
• Their company were already into Ruby / Jruby
• Points associated to raster
• Slap: source, lookup, algorithm, process
• Parallel with celluloid on github

Sponsor Day Programming Highlights OpenGeo’s Vision

New York, NY, April 18, 2012 — OpenGeo, successfully held the first OpenGeo User Meeting on April 12, 2012 during Sponsor Day at FOSS4G North America in Washington DC. As Eddie Pickle, OpenGeo CEO, mentioned: “FOSS4G North America and Sponsor Day would not have been possible without our fellow Gold Sponsor RadiantBlue and Venue Sponsor RedHat.”

Eddie Pickle began the day with an overview of OpenGeo, its clients, and a vision of its future. This was followed by a detailed look into the OpenGeo technical roadmap led by Tim Schaub, OpenGeo CTO. Building on the technical roadmap presentation, various OpenGeo developers gave technical demonstrations led by Juan Marin Otero, Senior Implementation Specialist: Justin Deoliveira presented on the future of web-based spatial processing in GeoServer, WPS, Geoscript; Paul Ramsey discussed the state of Spatial IT and how it differs from the conventional desktop-based GIS paradigm; Tim Schaub presented on building applications for web and mobile audiences using the latest features in OpenLayers and GeoExt/GXP; and Matt Priour announced the recent launch of MapStory, a platform for telling stories with maps based on GeoNode. These presentations provided users with an inside view of the latest existing and planned capabilities of OpenGeo technologies.

During the Sponsor Day lunch, a policy-focused panel comprising speakers from RedHat, the US Department of Defense, and the Institute for Defense Analysis discussed policy initiatives related to the acceptance and implementation of open source software within the federal government.

The afternoon sessions began when Dr. Christopher Tucker, a key advocate for open source and open standards within the US government, delivered an inspiring message on the “Open Future”. This was followed by panels highlighting successful deployments of OpenGeo technology that featured open source geospatial innovators and practitioners from over a dozen government agencies including the US Department of State, FCC, NOAA, NGA, Army Geospatial Center, and the New York City Department of Information Technology and Telecommunication (DoITT).

Commenting on the OpenGeo User Meeting, Eddie Pickle noted, "OpenGeo is looking to provide the best possible educational opportunities for users of the OpenGeo Suite. Sponsor Day at FOSS4G North America allowed us to support both FOSS4G North America and our software users. The day proved to be an exciting and informative forum on the open source geospatial ecosystem and how OpenGeo fits into its future."

We're now in FOSS4G-NA 2012 day 3. The conference has been great so far, with high quality talks and a stellar event organization. I've been busy enough to not find enough time to clean and complete my conference notes, but don't worry, I expect to share my summaries early next week. And to my satisfaction, I learned much more again than I expected... some important projects should have receive more visibility here on Slashgeo, I'm eager to tell you about them! More soon - thank you for your patience.

I'm glad to announce that Slashgeo is a proud media partner of the first FOSS4G - North America 2012 conference. We certainly have experience with these after having participated to the previous three FOSS4G conferences. We'll provide on-site coverage of the event and share with our users any pertinent related news. We already mentioned FOSS4G-NA 2012 a few times and here's how the about page presents it:

"FOSS4G conferences highlight the latest and greatest projects from the Open Source Geospatial foundation OSGeo.  This year’s program targets a range of interests with the following tracks:

• Technology & Tips Track: Learn about the latest open source software from the developers and power users themselves. What are the new features? How do you get the best performance? How do you configure for the best results? For power users, deployers, system integrators and developers!
• Deployment & Decisions Track: Learn who is using open source geospatial software, and what their experiences have been. What kinds of organizations are deploying? What scale are their systems? What were the business drivers behind their plans? For managers, project leads, consultants, and other decision makers!
• Ideas & Trends Track: Where the latest tastes meet and mingle! Open data and crowd-sourcing, balloon photography, personal sensor packages and hardware hacking. For everyone with an itch to scratch!

Over 900 international attendees came together for FOSS4G 2011 in Denver. The event fostered new ideas and enthusiasm to build great things. Join us in Washington, DC this spring to make magic again!"
