Although if you are not using Topology, this will likely lead to lots of slivers between the states.

We have an app that needs to generate a map with state outlines, but needs to keep the total amount of data as small as possible. Fortunately, we don't need precision, a rough approximation of the outlines is fine. Does anyone know of a source of approximate state outline data? Alternatively, does anyone know of a tool I can use to reduce the number of points in a geometric feature, while retaining the general outline? Something that would take a complicated boundary drawn with points every 100 meters and return a simplified boundary drawn with points every 10 kilometers?
