<DIV> </DIV>
<DIV>"95% less than" means "20 times less than", actually.</DIV>
<DIV> </DIV>
<DIV>Do you mean "5% less than"? (you expected 100 and got 95)</DIV>
<DIV> </DIV>
<DIV>I have made a test with the attached shapefile and:</DIV>
<DIV> </DIV>
<DIV>
<DIV>gvSIG says it's length is 50.12 m
<DIV>Google Earth says it's length is 50.06 m</DIV>
<DIV> </DIV>
<DIV>The difference is about 0.12 %.</DIV>
<DIV> </DIV>
<DIV>Can you send your example?</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Regards,</DIV></DIV></DIV>

<DIV><FONT face=Arial size=2>Dear All,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have recently digitised linear features in Google earth that I have converted from kml format to shape files. I wanted to tabulate the total distances of these lines in gvSIG so I used the available facility in vector line tools in Sextante. However, the distances were on average 95% less than the distances noted in the features' properties in Google Earth. I then used gvSig's own facility for determining lengths of polylines and these were the same as those determined in Sextante. I'm working in WGS84 - so what could be causing the differences? And which system is correct, Google Earth or gvSIG? </FONT></DIV>
