How is the best way to manipulate data from specific distance from an axis?
Problem:
I have a road axis;
I want to manipulate 1Km of data from each side of this axis;
Pixel size is 1m X 1m
Axis Length is 2,000 Km
I tryed to use one geotiff or one big geotiff, but the file in memory seams to have rectangular boundary and a huge amount of nodata.
My idea is to cut data into many small geotiff files,
but this does not seem to be the best solution. Any sugestion?
