Re: [mapserver-users] using gdalinfo.exe
Frank, Thank you for the response. Is there some other way to get some of the gdal info with a simple query? I'm not stuck on using gdalinfo... it just seemed like a good idea. What I need is the UTM Zone -- that's already specified (I guess) in the EPSG statement in the mapfile. Can it be extracted from there over the web by way of a URL / query?

Ken, I'm not aware of anyone doing anything quite like this. gdalinfo isn't setup to be used as a cgi, and doesn't return things html encoded or with a content-type header. And MapServer does not have an equivelent functionality. But, in theory, you could write a little gdalinfo script in php/perl/python that would execute gdalinfo on a passed argument filename and then return the result with a proper Content-type: text/plain header.

Ken, There is no stock mechanism for this, but you could write a custom mapscript application to pick this information out of the map file and return it as a web service. I would note though that MapServer does not normally provide access to stuff like file bounds to mapscript so there it is hard to provide very much information using mapscript itself. You could try setting up the dataset as WCS accessable, and then the WCS DescribeCoverage method would provide a variety of information about the file.
