Hi,<br><br>I have created a shape file via gdaltindex based a few thousand geotiff's.<br><br>I don't need all of the interior grids within this shape file just the exterior vertices's.<br><br>How can I convert this shape file so that it does not have the interior grid and just the exterior vertices's.<br>
<br>I am displaying this shape file within UMN MapServer and I want to increase the performance by eliminating the drawing of the interior grids.<br><br>Thanks,<br><br>John Mitchell<br clear="all"><br>-- <br>John J. Mitchell<br>
