Who can tell me the difference between remote sensing and aerial survey?

Aerial survey refers to aerial photogrammetry, which is mainly used for surveying and mapping, such as various topographic maps and engineering drawings.

Remote sensing mainly studies remote sensing geology and its related fields, such as remote sensing geological mapping, environmental disaster investigation and geological disaster assessment.

The data used is different. Aerial photography is used in aerial survey, and radar, SPOT, TM and other data sources can be selected for remote sensing.

Aerial survey requires accuracy, while the accuracy of remote sensing is generally lower than aerial survey, but it requires more accurate classification accuracy.
