Is anyone in the GIS community trying to publish choropleth web maps with a large (10s to 100s of thousands) number of polygons? and if so what's your current approach and what are the shortcomings of that approach?
My company is thinking about reviving an old project, but would like to get a sense of the demand before we invest too much time in something that may not be needed.
Features of the service would include:
- Support for millions of polygons.
- Ultra fast updates (recolor the maps in < 1 second, our goal is 60ms).
- Realtime query support (mouseover or click a polygon to display it's info).
- Bring your own data (upload your own shapes, classifications, etc)
- Built in Census Data (all census layers and data preloaded)
- Web access (no coding required)
- Overlay (display your published maps as overlays in Google Maps, Bing Maps, Open Layers, etc)
The core of this system is already working, but it would be a pretty major push wrap it in something useable. We're unsure at this point if there is enough demand to justify the effort. My apologies in advance if this isn't the appropriate forum for this sort of question.
