A web service for displaying color contours of your data, which you provide in the form of (latitude,longitude,data) on top of Google maps-- complete with dynamic map controls, satellite, terrain, etc.

This is sometimes called a heatmap, even if the data isn't heat-related.

With a simple lookup procedure, you can also display zip code related data, though we don't provide the zip code lookup just yet.

A wide variety of potential uses exist:

• marketing / $ales / income data
• crimelab!
• scientific / botanical / geologic data
  
• mining / minerology studies
  
• engineering / seismic report-outs
• weather
• econometric d.a.t.a
• you think of more!
  

The service is programmable via the simple HTTP POST mechanism, so you can include such maps in your own web site.

The user (or web developer) has control over

• blending level (local vs. large-region smoothing)
• granularity of the color cells
• other useful display parameters.

Works best on Firefox at this time...stay tuned for improvements for IE.
