I’m using IDL program. But I have a question how to convert different row and column number (row/col) to the same size of column and row number of 36 time series NDVI images. These images grouped into three different column and row numbers. When I do the subset I used the same shapefile and Geographic Lat/long (WGS 84) projection for all of them. So I’d like to ask why col/row numbers of these images is different. Second how to correct their size into the same size (col/row number)?
Thanks for your help
