This site that I did has been out there for a while, but I thought I would share it now becasue it does have some interesting geographical components to it. To be honest, the mapping portion is not all that impressive...it was done so that it the frontend was very very easy to understand and navigate for the less-than-average-user.
Its a site for Caldwell County, NC and its designed to give prospective business owners access to on the fly demographic data. It essentially buffers a property and returns the census block groups that are within that buffer. It then sums all the rows of data up and creates percentages, etc etc.
So it makes this very sharp report..but then what. Well, you can print it, save it, email it, etc. In fact, just about anything that you can create and output to the browser, you should be able to:
* store as url variables * insert into a db, text file, etc * recall them when requested by the user at a later date
Think about all those possibilities. Store user sessions, map extents, layer lists, renderering preferences, etc...
Site was written in Coldfusion with the Coldfusion ArcIMS Connector and the backend db was sql server and ArcSDE 8.3
