Batch Geonews: AutoCAD Worm, QGIS Cloud, Map Calls, Shapefile Spatial Index Revealed, and more

Here's the recent geonews in batch mode.

On the open source front:

  • Thanks to reverse engineering, GDAL/OGR can now use the Shapefile native .sbn spatial index, to understand the context: "The Shapefile format had been documented since 1998, but the documentation was limited to the minimum core, that is to say the .shp file that contains the geometries and the .shx that is an index to the geometries. However the format of the .sbn file, that was known to contain spatial index (aimed at speeding up spatial filters), has never been published."
  • Another entry on the visions for OpenLayers 3
  • Here's an entry on QGIS Cloud, a hosting service for QGIS Server and still on the QGIS topic, Styling temporal (time) data in QGIS

On the Esri front:

  • APB shares their thoughts on Just What is ArcGIS Online for Organizations?: "It’s a cloud hosted platform for a GIS intranet for an organization."

On the web mapping front:

  • Microsoft added thousands of international shopping malls to Bing Maps

  • Even geospatial files are prone to virus, AutoCAD Worm Medre.A Stealing Designs, Blueprints
  • On a more positive note for Autodesk, James mentions Project Artoo "that allows AutoCAD Map 3D users to perform geometry cleanup operations on geospatial data"
  • Also from Slashdot, here's what can happen when you map someone else's data, PadMapper Gets C&D From Craigslist Over Apartment Listing Maps
  • Via OGD, with Map Compare, you can now compare side-by-side 35 basemaps from OpenStreetMap versions to Google Maps versions and Yahoo, Microsoft, Apple and more

In the maps category:

  • That's an interesting and probably sad map in an entry named The Great Indoors, or Childhood's End?, showing how much less we allow our children to go away from the house over the last decades
  • The annual map of the Tour de France in Google Earth

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.

Open Alternatives to Google Maps

Lately there was a not much surprising news about Google products and services. Among other things Google has changed the Google Maps API use policy and will charge to those users that exceed some download limits.

It is well known that Google Maps is one of the most (or the most) famous mapping service used around the net and it starts the web GIS revolution some years ago but hopefully it is not the only API we can use. Bing and the discontinued Yahoo Maps, are great competitors but there are great and open alternatives to use.

I wrote this post to summarize the most important JavaScript API alternatives to Google Maps.

[Editor's note: this anonymous submission mainly discusses OpenLayers, Polymaps and Leaflet]
