  2. Yusheng, groundwater levels are usually determined by depth to water in bores/wells. The depth of the water table is calculated by subtracting the depth to water from the surface elevation of the well. The values are then gridded/contours and water table surface layer can be created. It can even be shown as a layer within a 3D block diagram. Remote Sensing as in satellite imagery and aerial photography can be a good tool in determining locations to drill for groundwater, but would give no indication of depth of water table. Identifying surface water bodies using remote sensing can assist in regional groundwater studies and determination. Geophysics like ground magnetics and gravity surveys can help determine likely localities where one would find groundwater but one needs to drill a well to find the water. Let me know what type of data you have and I will give some pointers on how to use the data.

  3. Andrew can you give me idea how to graph the ground water using remote sensing and how exact it is. We are supposed to do a project with GIS mapping of ground water table. We have a team of GIS expert but i really want to know how exact they can map the ground water. Can you help.
