Bloggage update: added British Geological Survey web mapping services to East Anglia web map, in order to compare historic and current geology. The Snapshot format also give the catalog a variety of viewing options of the catalog. As I say in More East Anglia Web Mashups , such small scale maps are intended to engage and inform, and point to more detailed maps and fieldwork or possible avenue of research subject to an upcoming paper.
(late) bloggage update: Global vector datasets on AWS, see the opportunities and challenges.
I wrote a decade ago at Esri that accuracy in geological mapping and interpretation, need no longer be a compromise of computer system speed and storage capacity. Well it appears like we are finally getting to achieve that with the variety of platforms available to we the people as data democracy starts to gain traction.
A couple of years ago I started developing MyGeoCloud an open source project that ties PostGIS, MapServer, TileCache and OpenLayers together in one integrated geospatial solution. Since then a lot has happen with the project: The development has moved from a big consulting firm to a small startup called MapCentia.com, the project is renamed to MapCentia GeoCloud, the codebase is rewritten and Leaflet, OpenLayers3 and Elasticsearch are included in the stack.
The goal of the project remain the same: Provide an all-in-one open source solution for storage, geospatial operations, geospatial web services and web mapping.
A more detailed description of the project can be found here: www.mapcentia.com/en/geocloud
Get the source code here: github.com/mapcentia/geocloud2 or quickly spin up a server at Amazon AWS: www.mapcentia.com/en/geocloud/installing_geocloud.htm
Bloggage update: My previous post on Standards and Metadata stated how careful documentation and appropriate metadata high-grades any information that is shared online by giving origin, context and other information. It helps build bridges and I quipped a well-known tear down this wall that also closed my second last post on free data and apps.
In that post I described how UK Parish data underpinning my geo-history project came from publicly released Ordnance Survey Boundary Line data. I attributed the data in both figures of that post. And giscloud.com also adds a data source to each of their web maps. Now Mapcentia, whose service is used to post said geo-history project, also added a metadata button next to each Table of Contents item, as entered in GeoCloud2 database - and to repeat them, see how it works on my map there (and thanks Martin for the referral).

Tidbits made me aware of Poppy 3D, a very affordable box that turns your iPhone into a 3D camera and I thought this is of interest for geospatial-related usage.
Tibtibs' summary: "The first magic gizmo I saw accomplishes its wonders with mirrors, if not smoke. The Poppy from Hack Things converts any iPhone 4 or later (or fifth-generation iPod touch) into a 3D stereoscopic camera and viewer. Slot your iPhone into the Poppy, and rotate the outer portion of the Poppy 180 degrees to take two side-by-side videos or photos from slightly different vantage points. Then rotate it back to convert the camera into a viewer and watch your video in 3D. Anyone who grew up with a View-Master (still going after 70 years!) will feel a twinge of nostalgia upon using a Poppy. The Poppy is available from Hack Things for $59."
Happy 2014 to all our readers! Yes yes, I'm later than I'd like, but anything geonewsworthy will be shared with you. Thanks for your patience, and you're still welcomed to contribute!
Via O'Reilly, I learned about MIT's WiTrack, used for Through-Wall 3D Tracking Using Body Radio Reflections. You can't do anything to stop being tracked!
O'Reilly summarizes it this way: "Witrack — tracks the 3D motion of a user from the radio signals reflected off her body. It works even if the person is occluded from the WiTrack device or in a different room. WiTrack does not require the user to carry any wireless device, yet its accuracy exceeds current RF localization systems, which require the user to hold a transceiver. It transmits wireless signals whose power is 100 times smaller than Wi-Fi and 1000 times smaller than cellphone transmissions."
They give examples for entire-home gaming, but for elderly monitoring and fall detection too.
Here what's probably our latest geonews in batch mode entry for 2013, have a nice holiday break!

Bloggage update: It took five days (after hours) to stand up, learn, tweak and display my East Anglia Fenlands project on Mapcentia's web service. It started with a GISuser group post on LinkedIn on Monday, I used my Amazon Web Service free EC2 trial and GeoCloud2 under beta, and by Friday I had it working and styled. No small thanks to Martin Hogh's original work and help, the result is a simple yet modern and pleasing web map. Not only can I serve up the results of my round-trip Ordnance Survey polygon corrections, but I can also serve up my East Anglia Fenlands project quickly and effectively.
Almost everything geospatial deals with symbols on maps or other types of displaying mechanism. Here's a new source of symbols coming from the OGC MetOcean DWG, the 'World Weather Symbols' available on GitHub.
It is described as "A complete set of WMO weather symbols in SVG with full metadata." It's not a version 1.0, but they are fully usable right away and there's "A set of pre-generated PNGs are available for download [...]". From the same source you can get the 'World Meteorological Organization - Regional Associations' (WMO-RA) in geojson, which is vector data representing the "Six regional associations are responsible for the coordination of meteorological, hydrological and related activities within their respective Regions [...]".
Other openly available geospatial-related symbols sources that I'm aware of include:
Any other pertinent source?
