OK, so I got the conversion working, probably a newbie mistake, as the solution was mainly to switch datum, i.e. change the command from<br><br><span style="background: transparent none repeat scroll 0% 0%; -moz-background-clip: border; -moz-background-origin: padding; -moz-background-inline-policy: continuous;">ogr2ogr "KML" LINE.kml LINE.shp</span><br><br>to<br><br>

<br>However, before realising that, I managed to compile and install gdal 1.7. Using gdal 1.7 did not crash reading the file using the initial command line but gave a warning about coordinates exceeding limits, and from this I eventually realised my error! Thus, I am not sure whether gdal 1.5 would still work using the correct conversion (probably).<br><br>The next problem is to display the kml file on a map; there are about 500 polylines ranging from a few to hundreds of points each. Sending this to google maps (by using "My Maps"->"Import") displays the data over several tabs, which is undesirable. Any ideas on how to display all the data simultaneously?<br><br>Thanks,<br><br>Mattias<br><br><br><br><hr id="stopSpelling">Subject: Re: [gdal-dev] ogr2ogr .SHP to .KML conversion problem<br>From: gregcoats@mac.com<br>Date: Tue, 2 Feb 2010 18:06:28 -0500<br>CC: gdal-dev@lists.osgeo.org<br>To: powerphysics@hotmail.com<br><br>
