Method and system for classifying a terrain type in an area

A computer program comprising at least one non-transitory computer-readable storage medium having computer-readable program code for classifying a terrain type in an area embodied therein, the computer-readable program code being configured to execute the steps of:

• obtaining a plurality of overlapping aerial images of the area;
• calculating at least one terrain type index for each part of each of the aerial images, where the at least one terrain type index represents the terrain type;
• determining at least one effective terrain type index for each part of the area based on the calculated at least one terrain type index for each part of each of the aerial images;
• and
• classifying the parts of the area for which at least one pre-determined conditions is met as containing the terrain type, wherein at least one of the at least one predetermined condition relates to a value of the determined at least one effective terrain type index.

A system for classifying a terrain type in an area, the system comprising:

• one or more memory storage areas configured to store a plurality of overlapping aerial images of the area;
• and
• a processing unit configured to:
• calculate at least one terrain type index for each part of each of the aerial images, where the at least one terrain type index represents the terrain type,
• determine at least one effective terrain type index for each part of the area based on the calculated at least one terrain type index for each part of each of the aerial images, and
• classify the parts of the area for which at least one pre-determined conditions is met as containing the terrain type, wherein at least one of the at least one predetermined condition relates to a value of the determined at least one effective terrain type index.
