Hello everybody,
i need to create an higher resolution image: i would like to display
the tematic content of a Landsat7 (bands 3 - 4 - 5) on the resolution
of greyscale SPOT5.
both images are georeferenced and clipped on a specific ROI.
Landsat has 28.5m res on ground while SPOT5 is 10. it seems reasonable
to me to performe such operation: i could try also to blow it up to
2.5m (wich is the original spot5 pan output res) but seems to much of a
computing and a too hazardous operation.
i am trying to read the land changes on a small area from 1991
(Landsat) to 2003 (Spot) and i would like to have a common pixel size
for the images to be compaared.do it sound reasonable? i am currently
using erdas but open to any suggestions...
