Forest edges and clearings

General info
Scale: 
1/100 000 to 1/25 000
Spatial resolution: 
30 to 10m
Required processing: 
Pre-processing: orthorectification and georeferencing, Pixel-based classification of the forest, Vectorisation of the edges.
Data requirements: 
Archived High spatial resolution satellite images (e.g. LANDSAT MSS or TM, TERRA-ASTER, SPOT)

Georeferenced polygons of forest edges and clearings.

Why using remote sensors?: 

In some conflicts, the forests are used to hide the troops making temporary clearings and/or modifying their boundaries.
To improve the SHA delineation, the forest edges at the time of the conflict can be mapped from free archived images covering large areas since the 70's.
