Although if you are not using Topology, this will likely lead to lots of slivers between the states.<br><br><div><span class="gmail_quote">On 4/24/07, <b class="gmail_sendername">Aaron Racicot</b> <<a href="mailto:aaronr@z-pulley.com">

</a><br>Subject: [UMN_MAPSERVER-USERS] Simplified state outline 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>-- <br>************************************
