Dry walls

General info
Scale: 
1/1 500 to 1/250
Spatial resolution: 
0.5 to 0.05m
Required processing: 
Orthorectification and georeferencing of the aerial photographs, application of the detection algorithm.
Data requirements: 

Aerial photographs

Georeferenced polygons or lines delineating the dry walls.

Why using remote sensors?: 

Dry walls can be detected visually or semi-automatically on aerial photographs. When located in areas with evidence of military activity, they are likely to indicate the presence of mines.
