In+ersec+ion for Spatial People

Bloggage update: Vector online GIS appears to be gaining traction. These emerging technologies contrast with Esri who offers a slew of tools on the desktop and in arcgis.com like mature web mapping services and model building. But these newcomers offer a service to process GIS functions online and allow to load data direct from web source further augmenting their web performance. Here I compare how I used a 180K vector dataset from NOAA NGDC described previously on these alternate methods. 

Bloggage update: Here is a small selection of mapping tools available on the iPad. Some are from the Appstore, others simply from the web. The upshot is that while there is a variety of apps available for iPads, web maps appear to work just as well. The advent of HTML5 will especially help in rendering vector maps on smartphone limited bandwidth.

Here's the recent Google-related geonews, it covers a longer time span than usual.

ikiMap (www.ikimap.com) is a free web service which allows its users to create and share their maps.

The objective is to combine the concept of a social network together with the use of cartography and maps.

Users can create their own maps (by uploading files in KML, GPX…formats or directly by drawing on the map), vote for other users maps, add comments, create groups of friends, theme channels and more! Users can actually label the map as private and grant access to it only to certain people.

ikiMap is a free service, and it's based on freeware:

* OpenLayers (http://openlayers.com/)
* MapServer (http://mapserver.org/
* PostGIS (http://postgis.refractions.net/)
