I'm looking for any case study with this information and I'm interested in polygon or raster data. I've already looked for an example from Brazil, Colombia and India but without any success.
Based on this study I would like to compare different techniques of calculations of areas.
I thank you for your help.
DEM: SRTM 90m Digital Elevation Database v4.1
population: Gridded Population of the World (GPW), v3
@ Christian Jolk: Thanks for your hints.
Are there any databases for mass movements (in polygon or raster format)?
DEM from SRTM freely available between ca. 60° south to 60 ° North on all continents in 3 arcsec resolution (in mid-latitudes this is roughly 60x90 m,
From the USGS DEM data from the Aster-Stereo-Satellite are freely available over the whole world in 30 m gridded resolution, sometimes up to 15 m.
No information on any landslide data availability
the italian government offers a WFS service for a catalogue of landslides according to their type and location. i have never used it directly, but here's the link
http://wms.pcn.minambiente.it/ogc?map=/ms_ogc/wfs/Catalogo_Frane.map (spatial resolution 1:25.000)
Also, there is a free SRTM DEM 30 m resolution in the DLR site.

In Colombia, in last years the Servicio Geológico Colombiano (SGC) through service SIMMA has allowed the online consult of mass movements in the country, please visit
http://zafiro.ingeominas.gov.co/simma/
to consult, i think that the databas is still debugging but is the only dataset of this , attachment is another document.
