Line 6: y-coordinate of center of upper left pixel.Line 5: x-coordinate of center of upper left pixel.Line 4: NEGATIVE of y-dimension of a pixel in map units.Line 1: x-dimension of a pixel in map units.A world file is an ASCII text file associated with an image and contains the following lines: GIS software (free or off-shelf) you can import the image and add any overlaying dataset without the distraction of unwanted layers.Įach of the RIDGE radar image has a "world file" associated with it. Each RIDGE radar image is created separately without backgrounds on the image and in a standard geographic projection referenced to North American Datum 1983 (NAD83). ![]() The best feature about the RIDGE enhanced views of NWS Doppler radar images is that each image can be incorporated into GIS software. ![]()
