If you'll remember a little while back, PHPBuilder.com posted the first part of a series entitled "GIS Mapping with PHP". Well, this moring, they've posted the second part of the series.

In GIS Mapping with PHP: Part 2 they build on the foundation set in the first article and take it a step further: The main limitation with this system is that you are restricted as to what background you can use. You have to have a predrawn raster image drawn in the correct scale and projection for the information you want to display. What if all you want to show is the location of a house in Prince Edward Island? Well, the answer lies in vectored images - images that can be resized, scaled, and even zoom in and out with ease.

They describe how to take sample maps (and even .E00 files if you have them) and create detailed specs based on the map, pair it with some PHP functionality to create a sample map that will allow you to plot a point simply and easily.
