Jason Harshman writes "A new site called Shapefile Connection uses Google Maps to pin point markers where organizations provide free GIS data for download. Data is only offered in some states, but more pin markers are added on a regular basis. The site also offers links to GIS data based on specific themes, i.e. GIS data on Hurricane Katrina as well as links to other GIS resources. Visit Shapefile Connection.com for more information." This is not the first similar initiative.

Vector One discuss the future of shapefiles, the de facto standard, and ESRI's Geodatabases. From this must-read blog entry: "a) the geodatabase is a significant upgrade to the shapefile; more robust
b) the geodatabase will be exportable and include several feature classes of different data types; leading to the thought that the database will ship with the application." This topic was to subject of a previous poll with interesting comments.
A Collaborative Shapefile Repository 1 comment

Andre Lewis writes "While coding a Google Maps application recently, I needed some neighborhood outlines for major cities. Various searches yielded nothing, which made me think: what if we could all contribute to a simple wiki-style shape repository? ShapeWiki was born soon thereafter. ShapeWiki features 1) a point-and-click editor for creating new shapes; 2) a tagged, searchable shape database; 3) import and export in GeoRSS, KML, and JSON. Shapes are offered under the Creative Commons Attribution License. Notice the "Reference Image" when you try creating a shape. Enter an image URL there to pin an image to the map so you can trace neighborhoods, etc. Here's an image of the neighborhoods in San Francisco: http://real-estate-us.com/images/SanFranciscoNeigh bourhoodsCA.gif"
