[GIS] Elevation info for multiple lat long coordinates

elevationgoogle earthlatitude longitude

I have a list of 100 lat long pairings that I wish to get the elevation data for.

I am familiar with Google Earth and I can plot each of these points but when I check the properties there is no elevation info other than the info at the bottom tool bar which would require me to manually write the elevation down.

Is there another way that I can query all 100 coordinates to get the elevation data?

Best Answer

You can use Point sampling tool plugin for Qgis.

Hope your coordinates pair are in excel or text delimited format.

Open it in Qgis and convert to Shapefile.

Download DEM of your area of interest (from Earth Explorer or somewhere else). If number of DEM is more than one then convert them to VRT.

Load the shapefile and the VRT/DEM and run point sempling tool, select the columns you want in result along with elevation value and save it.

You are done.
