Open Source Geonews: HSLayers, Proxy4OWS, the Worst of OpenStreetMap, AP moving to TileMill + Leaftlet, and more

Still in my geonews catching up process, here's the open source-related geonews not shared yet.

  • Via LinkedIn I learned about HSLayers and Proxy4OWS,
    • For HSLayers: "HSLayers is yet another JavaScript Mapping framework. You can use it for building rich mapping portals, as well as use it’s parts for improving your simple OpenLayers-based map."
    • For Proxy4OWS: "It is transforming OGC WMS request types from the client, into WCS or WFS requests, so that the target server can accept them."
  • For OpenStreetMap, I liked the 'Worst of OSM' page showing failed imports, I guess we wouldn't see this from proprietary providers (via)
  • For those unable to move to 2.0, PostGIS 1.5.4 was released
  • If you want to learn about GeoExt 2 development
  • GeoNode 1.1.1 was released
  • And so was MapProxy 1.4.0
  • As an indirect user of GEOS, I'm happy that GEOS graduated OSGeo incubation
  • The OSGeo also informed us of the First Open Source Geospatial Laboratory in South America and First African Open Source Geospatial Laboratory
  • You might have an interest in the Comprehensive preview of MapGuide Open Source 2.4 series
  • libais 0.7 was released: "C++ decoder for Automatic Identification System for tracking ships and decoding maritime information"
  • APB informs us  that the famous AP, Associated Press, is moving to TileMill and Leaflet for their interactive maps

CartoDB: Map, analyze & build applications with your data

Vizzuality announces the launch of CartoDB 1.0, an open source platform to map, analyze and build location aware apps with your data in the cloud.

Import your data in a click. Mashup datasets. Create beautiful maps. Use CartoDB to explore and discover new relationships in your data. Publish and share your work. Enjoy.

Journalists, scientists, developers and data explorers can use CartoDB to create dynamic maps with ease, and with v1.0 have access to a whole world of data to explore from OpenStreetMaps.

With CartoDB dynamic rendering you can create truly interactive visualizations using HTML5, real-time maps and location aware mobile apps. CartoDB is Open Source, you are not locked into any vendor platform.

CartoDB allows you to use your data layers with all popular providers (Google Maps, Bing, MapQuest) or with free sources like OpenStreetMaps. Thousands of users like NASA, The Wall Street Journal and the United Nations are already using CartoDB.

Batch Geonews: Landsat 5 Suspended, Wikipedia Mobile Switch to OpenStreetMap, Your Facebook Connections Map, Vertical Datums, and much more

It's Easter and I find myself aggregating geonews for you - don't you see how much I love you ;-) Expect less news this week since I'll be participating to the FOSS4G-NA conference. So here's the latest geonews in batch mode.

In the open source and open data front:

  • Slashdot discusses a story named Wikipedia Mobile Apps Switch To OpenStreetMap, away from Google Maps, related, James Fee links to a NY Times article on bypassing Google Maps with OpenStreetMap
  • and via @teller another article is named Microsoft backing OpenStreetMap, creating Google Maps competitor
  • Numerous sources mentioned the beautiful watercolor OpenStreetMap style from Stamen and here's how they were created (via Wes)
  • An entry discusses the differences between the Portable GIS and OSGeo Live tools
  • There was a few entries on QGIS; one on the qNote plugin, detailed instructions for installing QGIS Server on Windows 7 and on Ubuntu, the custom form feature to streamline data entry, and an entry on the enhanced MS SQLServer support
  • With PostGIS 2.0 recently released, here's an entry on validating vector features
  • Here's a discussion on OpenStreetMap should be more like Facebook

In the miscellaneous category:

  • The Landsat 5 mission is officially suspended after 28 years, we mentioned its recent problems
  • Kurt shares four entries on vertical datums
  • APB shares an Esri Developer Summit RoundUp
  • APB also shares an entry named Doctor’s Offices and Access to primary health care - Esri Map Story
  • The GEB mentions GraphEarth, a 25$ tool to generate charts for Google Earth
  • Several blogs participated to the raw data vs API discussion
  • This infographic will inform you on the current state of MapQuest, MapQuest also have a new section to explore U.S. National Parks
  • WebMapSolutions offers two entries whether we should retire the term GIS - my take is that GIS is useful since it refers to something specific and unique
  • Somewhat related, Very Spatial shares entry on the new GIS end-user: "These users know how to navigate and interact with consumer maps and expect all their interactions with spatial technology to be this simple. They don’t, in any way, want to “see” GIS or have to learn a new vocabulary of terms like vectors, georeference, buffer, and shapefile." No pain no gain?
  • APB mentions a U.S. Congressman Introduces “Map It Once, Use it Many Times Act”
  • O'Reilly shares an entry on the do's and don'ts of geo marketing
  • Spatial Sustain has an informative entry named Let the Drone Mapping Race Begin

    • Ten Things to Know about the Geospatial Technology Competency Model
    • And finally The Top 10 Reasons Why You Need to Know About the U.S. GeoTech Center

In the maps category:

  • Many sources shared the beautiful WebGL U.S. wind map also discussed over Slashdot
  • TMR shares a nice short video visualizing the world's ocean currents on the globe

MyGeoCloud ties PostGIS, MapServer, TileCache and OpenLayers together

MyGeoCloud is a new OpenSoure project and a web service. It offers geospatial storage, WMS and WFS-T services for accessing data and transactions. Besides that it offers a built-in web mapping client and online editing of data. But MyGeoCloud is also a platform on which you can build your own location based web applications using a JavaScript API.

The core component of MyGeoCloud is the PostGIS database software, which is used for storage and geospatial operations. MapServer is used for map rendering and for tile caching TileCache is used. OpenLayers is used for the web map clients. The WFS-T service is implemented in the code base.

The goal is a all-in-one solution for storage, geospatial operations, geospatial web services and web mapping.

PostGIS vs Oracle Spatial: PostGIS Wins

Unless you're new here, you've heard of PostGIS several times. It's really hard to find documentation about spatial database benchmarks since, if I'm not mistaken, proprietary software licenses often prohibit publicly sharing such benchmarks (am I right?). And I guess there's at least one good reason for this: doing fair benchmarking is difficult to accomplish. But here's one (currently available) benchmarking report comparing PostGIS (PostgreSQL) and Oracle Spatial.

From the conclusions of the 46-pages report: "From the experimental results that we saw, we can conclude that Postgres performs better than Oracle 11g both in the Cold Phase and Warm Phase. Though in few queries Oracle 11g performed better but on the whole Postgres overpowered Oracle 11g. In the warm phase in 3 out of 4 queries Postgres performed significantly well, from this we can conclude that Postgres has better automatic memory management capabilities and page replacement policies. [...] Since Postgres uses the underlying GEOS (Geometry Engine - Open Source) library functions for implementing the geometric operations whereas Oracle 11g implements them on its own, and since in majority Postgres performs well, we can conclude that GEOS geometric algorithms are more efficiently designed than Oracle 11g. And also Postgres planner is more efficiently designed to take advantage of any available indexes to use in queries for achieving better performance whereas in Oracle 11g we saw that we have to specify them explicitly through functions."

Here's what Paul Ramsey of the PostGIS fame has to say about it: "Methodologically there are two obvious issues: one is that the Oracle database was on Windows while the PostGIS database was on Linux; the other is that neither database got any tuning, they were both installed and run with default parameters. However, this is one of the nicer comparisons I have read: concise, focussed and with enough technical detail to evaluate what's going on."
