<table cellspacing="0" cellpadding="0" border="0"><tr><td valign="top" style="font: inherit;"><p>Hi,<br>
I'm using GRASS GIS to help me model the Rouen les Essarts race course.</p>
<p>One of my aims is to take a nice grayscale image to use in deforming mesh topology. The circuit straddles two tiles and the shading is markedly different.</p>
<p>How can I either fix one or re-color both from scratch based on the elevation data?</p>
<p>Should be trying to get tessellations right out of the application?</p>
<p>Thank you</p>
