Hello there,
I need to compare elevation of same point between two dates namely before and after 2000.
Can you please tell me where can I find DEM of my city before 2000 or even older ?
https://glovis.usgs.gov/
get the data
You can search on NASA's Earthdata portal at https://earthdata.nasa.gov/ . It is a relatively new portal, but all the data content available from NASA is there.
Is there any way to use Remote Sensing and GIS for mapping of Aquifer for the exploration of Ground water?
