ASTER GDEM v1 to be reworked

I've realised that I used a less than ideal setting for the Level0 setting. I should have used 24 but I used 22. I believe this value relates to the number of bits allocated to addressing points on Level 0 - the level in which the detailed 10m contours reside. 24 bits corresponds to a resolution of 2.4m vs 9.6m for 22 bits. Perhaps this explains why there was a considerable loss in the resolution of the contours after converting it with cgpsmapper.

Will re-compile and upload an updated map soon. Am expecting it to be bigger but with more detail preserved.
