Density map for image coverage

Discussion created by JannK on Feb 22, 2012

I have a large set of satellite images and I would like to create an overview map indicating how often certain areas are covered. I.e. I could imagine s.th. like a fishnet over the entire study area where coverages are indicated per cell (e.g. as different colours or so). Is there any way to create an 'overlay-density-plot', e.g. from the calculated footprints of the images?

I'd be thankful for any hint!
