[gdal-dev] generate raster "GeoTIFF" for given lat long bounds at particular zoom using GDAL

[nicolas.cadieux at archeotec.ca]

Hi,

If you want a standard x and y, you will need to reproject using a 
projected coordinate systems like (WGS84/UTM Zone 18).  Then, you will 
get a square pixel resolution that is in meters.  If you use WGS84 
Long-Lat, grids or pixels are almost square at the equator but become 
more and more rectangular as you go North or South.

Cheers!
Nicolas
