I downloaded early today four tiff images (dem) which I think will be suitable for my project. There were from ASTER Global Digital Elevation Model V003. Thanks very much again.

Thank you very much. I am trying to understand the information there in place, and later I will write to them, so to ask for the material for my project.

Hello! Excuse me, where could I download a suitable digital elevation model for the area arround the border between Mexico and Guatemala? I pretend to analize the hidrology, so I first need to determine the characteristics of some particular basins.

Thank you very much.

Hi and thanks. I obtained the images from ALOS PALSAR RTC. I looked for information in the files attached with the image but I couldn't find some usefull notes

excuse me, does anybody know which are the units for height in digital elevation models? I downloaded a tiff image from ALOS PALSAR RTC, and realized that height values were between 0 and 2, in a zone with mountains and plains. maybe kilometers?

Hi. I downloaded some tiff digital elevation models. But then I noticed that the height values were from 0 to 2. The images show mountains and valleys, could the values be in kilometers, or some other unit?
