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