There are better ways to put data on the web but my latest little project wasn't about the best way but the quickest way to get some spatial data into the hands of those unfortunate souls who don't have GIS software. The goals were pretty simple:
Take a single point shapefile (or other OGR readable vector data source)
Convert it into html/js that would use one of the web mapping APIs to display the points and all their attributes.
The output had to be a standalone, self-contained html file that could be emailed. No server side anything required.
This allows for a single command:
shp2Mapstraction.py bearboxes.shp bearboxes.html Yahoo
which produces an html file providing a Yahoo maps interface to the data; in this case the point location of all the bear boxes (food storage lockers to keep your stuff separated from the bears) in the Sierra Nevada.
Currently it just supports Microsoft Virtual Earth and Yahoo. I had to bypass Google because their key system is restricted by URL. And the mapstraction-to-openlayers connection wasn't working too well though I haven't really investigated.
Anyways, it provides a quick and easy way to deliver spatial data to anyone with a browser and internet connection.
