Topographic map updating using raster based datasets

Aerial images from conventional aerial photogrammetry technique has been used to produce photogrammetric map. Topographic map updating is necessary when there are changes on the ground surface. The Department of Survey and Mapping Malaysia (DSMM) policy states that topographic map scale of 1:50000 a...

Topographic map updating is necessary when there are changes on the ground surface.

The RMSE values for the planimetric coordinates differences between conventional aerial photogrammetry and CP, UAV and CP and WorldView-3 and CP were ±1.112 m, 0.892 m and 1.160 m, respectively.
