I am wondering if anyone can shed some light on the subject of pixel size values in raster images. We have come across a raster tif with a tfw that contains different x and y pixel size values. They are actually quite close in value but nonetheless different but in any event, we would like to know why and how such values would exist. Considering that a pixel size represents the relationship between the resolution of the image and the amount of ground each pixel covers, under what circumstance would different x and y values be necessary? Is this a function of a particular projection or what? If a pixel is a square and a map's scale is omni-directional one would think that a pixel represents the same ground distance in both directions. But then again, I am just a dumb guy looking for help. Any help you can provide would be appreciated.
