I created two raster files in ArcGIS and imported them in to IDRISI. I know they have the same spatial reference but the number of columns and rows differs between them. How do I get these two images into the same raster group file and is that even possible? I guess my question is, how do I go about balancing the columns and rows of my images. Thank you.
Here is my response to a previous post on the same issue:
In IDRISI, you can harmonize the spatial characteristics of your data using the module PROJECT (even if you have them in the same projection) In PROJECT select as input the image that you want to modify. Specify the output name and the output projection (if you need to change only rows and cols, then specify the same projection of your input data) Then go to "output reference information" here you can copy the rows and col and extent parameters from the file that has the correct extent or enter them manually. Run it and the output should have the same extent, rows and cold of the image you copied the parameters from. NEVER change the parameters from the metadata because- although the software will not complain - the output will be garbage as you will be modifying the structure of the raster file.
Thanks FlorS, I tried that,and it worked :)
