Dear Ijaz,

The followings are the methods used for landslide susceptibility mapping:

    The widespread use of GIS from the 80s and 90s, was a major impulse to the

environmental and thematic mapping, as it provided tools for data analysis and

modeling, previously very limited. 

 However, the emergence of Spatial Data Infrastructures is which emphasizes

conclusively the importance of environmental data and maps and relates them to basic cartographies.

 SDI allow the availability of the updated data, promote the production of new

sets of information and ensure the presence of metadata to report on the quality of the input data.

In a wider perspective, different geomatics techniques of data acquisition are used

depending on the scale:

 Land techniques for detailed studies:

 Terrestrial laser scanner (TLS),

 Photogrammetry (VNIR and TIR)

 GNSS and Surveying

 Wireless Sensor Networks (WSN)

 Aerial techniques: Photogrammetry and LiDAR for large (UAV) and middle scales

 Space techniques: Remote sensing from satellites for small scales
