<DIV> </DIV>
<DIV>I'm sorry you cannot have the view in EPSG:32610 and see the coordinates in EPSG:4326.</DIV>
<DIV> </DIV>
<DIV>As you say, the only exception to that is that the coordinates of waypoints are stored in lat/lon. We do this because the conversion to another projection is usually subject to a small error, o we prefer to store the coordinates exactly as delivered by the GPS.</DIV>
<DIV> </DIV>
<DIV>If you wish to see the cordinates in lat/lon you might reproject your ECW image to EPSG:4326 (in this case there's no error in the conversion, by the way). You can do this with FWTools <A href="http://fwtools.maptools.org">http://fwtools.maptools.org</A>. You only need to type these two commands in the DOS-like window (Windows) or terminal (Linux):</DIV>

<P><FONT size=2>Hi,<BR>using gvsig mobile 0.3<BR>loaded an ecw map EPSG: 32610<BR>bluetooth gps connected, icon shows on ecw map properly( i.e. displays where I<BR>know I am physically)<BR><BR>BUT, the GPS coordinates display in units that are not the coordinates I want to<BR>see. I want to view lat/long decimal degrees.<BR><BR>How to I configure gvsig mobile to do this.<BR>I thought is was under project applications, but it doesn't work.<BR><BR> GPS<BR>Display GPS coordinates in real-time<BR>The Display Coordinates tool (1) displays the real-time coordinates of<BR>the GPS position in the toolbar<BR><BR>I don't know how to change it so it displays in lat/long degrees. When I save a<BR>waypoint, it shows the coordinates as lat/long degrees.<BR><BR>I go into Project applications/view tab and there is the EPSG, which I put to<BR>32610(wgs84 utm 10N). But the extents show as meters or something( 529970.91489,<BR>530784.70880: 5032559.6379, 5033468.3745) and I change them to 122.50, etc, but<BR>they change back when restarting the project.<BR><BR>thanks,<BR>Tom<BR><BR>_______________________________________________<BR>Gvsig_internacional mailing list<BR>Gvsig_internacional@listserv.gva.es<BR><A href="http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional">http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_internacional</A><BR></FONT></P></DIV></BODY></HTML>
