[ka-Map-users] RE: how to calculate extent in mapfile

Tue Apr 10 09:17:31 EDT 2007

You can also use the ogrinfo.exe command-line utility which is in the tools/gdal-ogr directory. In Windows, I had to move it to the apache/cgi-bin directory to make it work. Also Quantum GIS will automatically put in the extent when it saves to a map file...that was phenomenally good information about Quantum in Sunday's post from PJE (name?) ... that should really be in  the wiki ... I downloaded it that day and really made a lot of progress (though I also had to get python 2.5 to make the save to mapfile work in Windows), I've been spending too much time trying to figure out why adding things in the wrong place breaks the map, what all the ENDs actually end, etc., and Quantum GIS really automates it so I feel like I've got half a chance to figure it all out now...

	Dear Shar,
	You can add your data (shapefiles) to your GIS software and draw simply a
	box around your data, and from the graphic box properties you can get the
	lower left coords, and the upper right coords.
	You can simply add these coords to your extent settings in the mapfile.
	with the following order minx miny maxx maxy.

	You can find attached a sample map file which will work for Jordan. you may
	need to adjust the extent slightly as needed.
	(See attached file: sample_en.map)
