EPA Supports WATERS Geospatial data through OGC WMS/WFS Services

August 5, 2008 - 9:58 pm

EPA appears to be using ESRI’s ArcIMS 9.2 OGC connectors to publish OGC WMS/WFS services of their WATERS data.

Good review of Mapnik for generating online maps

July 24, 2008 - 11:02 pm

1. Embed a map in the client’s home page (non-database driven ASP.Net which is essentially HTML) that depicts the county’s watersheds and some number of additional layers2. Let users click each watershed polygon to trigger an event that leads to them learning more about…
