</div>I use mainly Roadtrip and all is scripted without install. If I absolutely need Mapsource then Mapset toolkit is sufficient and not much more complicated than starting an installer. I think mkgmap has also an option to create a a control file for a Mapsource installer with some 3rd party package tool. But once you mess up Mapsource Mapset Toolkit is a must have to clean broken registry.<br>

</div>have used this combination for a compromise of speed/size/precision. as said srtm data isn't that good and 10m seemed overkill. with NED data it's a different story<br>
25m minor<br>
100m medium<br>
200m major<br></blockquote><div><br>In canada we have access to Natural resources canada contour data that is available as 20m contours.<br>Its the same contours that ibycus topo made.<br><a href="http://www.ibycus.com/ibycustopo/">http://www.ibycus.com/ibycustopo/</a><br>
<br>So its really relative... if you hiking then 10m contours is great... and same if mountain biking. .. but if your road biking, then it might be a little much.<br><br>So i can make a separate map for the 25 meter contours<br>

what did you use for medium and major contours?<br>

<br>Im fine with the quality of the SRTM contours (since there isnt anything else (that i know how to work with) that is better. :)<br> <br>Cheers,<br>Sam<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
