Part II: Simple example of shading zip-code boundaries using Virtual E(mattberseth.com)

submitted by mberseth(1385) 5 years ago

In the original article, I showed an example of plotting zip-code boundaries using Microsoft Virtual Earth and Ajax.Net. I received some feedback from John (SoulSolutions) suggesting that the transmission of latitude and longitude points could be optimized by using googles compression algorithm (described here) which exploits that fact that lat/lons can benefit from compression when there is little difference between adjacent lat/longs within a given sequence. I thought this was an interesting suggestion so I updated the example to include this compression algorithm.
