This is the same region (flat desert), using the MicroDEM

by MKSheppard

In 2000 NASA flew the Shuttle Radar Topography Mission (SRTM); which provided elevation data accurate to 3" for the entire world; which means the entire world has been mapped with an accuracy of 90 meters.

Link to FTP where you can obtain the data

Using this data and MicroDEM;

This is a completely flat map near El Alamein (Africa).

Thanks to this display filter, I managed to make visible the 10 meters elevation curves.

In this 14 km x 10 km desert map

Purple is -10 meters,
Cyan is above -10 and below 0 meters,
Blue is 0 meters,
Green is above 0 and below 10 meters,
Yellow is 10 meters,
Red is 20 meters,
