Satellite imagery of the shorelines of ancient Lake Megachad reveal that the lake has existed under two distinctive wind regimes, one northeasterly and southwesterly.
Satellite imagery has been used to identify thermal bars using their thermal characteristics as well as the concentration of suspended materials on their shoreward side, typically due to surface runoff to the lake.

As part of this project, geodetic measurements of the citadel were taken and these were combined with satellite imagery, regular photographic imagery and aerial photographs to create a map and digital 3D model of the citadel mound and the houses on top of it.
The authority provides a wide range of hard copy and digital products such as Certificates of Title, Property Sales Reports, Survey Plans, aerial photography, satellite imagery, maps and data, and are responsible for valuing the State's land and property for government interest.
Digital orthophoto quadrangle - type of aerial photography or satellite imagery
The feature was noted in U.S. satellite imagery of 1973, and in aerial photographs obtained subsequently, by William R. MacDonald of the United States Geological Survey, who originally described it to William A. Cassidy as "a possible nunatak having an outline similar to an elephant."
Satellite imagery (e.g., Google Earth) of the island shows three X-shaped figures and one Y-shaped figure in its northern half, built out of metal shipping containers.
There are also side-roads, like Jalan Sungei Poyan, Lim Chu Kang Road Track 11/13 and Jalan Bahtera, and including roads that are not listed on Street Directory but on Google Earth satellite imagery (due to MINDEF secrecy, such as the old Kampong Berih Road).
Google Earth satellite imagery suggests that the original runway length was 2000 meters.
Some remains of runways and taxiways can be seen on Google Earth satellite imagery.
