Canton Ticino landslides map
The catalogue of instability phenomena is registered in a database which stores all the phenomena of slope instability recognized in the territory and memorized according to its specific type (eg: landslides, debris flows, collapse). The interpretation of these phenomena is based on photo-interpretation (stereoscopic aerial photographs and orthophotos), through the analysis of the digital elevation model (DEM) with a resolution of 2 m by field surveys.
By 2010, the Institute has acquired a new stereoscopic digital station called ArcGDS, which allows to create 3D vector data working with high digital resolution image strips, displayed in stereoscopy directly into GIS environment.
Currently, with the mandate received from the Federal Office for the environment (UFAM), the activity "landslides photo-interpretation" is continuing with the analysis of the western and northen areas of Canton Ticino (Vallemaggia, Centovalli, Val Bedretto), for which it has been also compiled a cadastre of periglacial mountain shapes (such as rock glacier moraines and glaciers).

Osogna and Grono quaternary geological sheet
In 2011 the Federal Office of Topography (swisstopo) engaged the IST in the framework of the GeoCover project, which seeks to acquire and integrate geological vector data of Switzerland. This project aims to create a database capable to carry out activities related to natural hazards, the environment and research.
Specifically, the geology sector has been taking care of the realization of the vector data regarding 1293/Osogna and 1294/Grono quaternary sheets through the analysis of aerial photos and orthophotos, DEM analysis with a resolution of 2m and soil survey to characterize existing forms and deposits in the areas assessed.
Beyond the pure geological quaternary mapping, the data acquired within this project will serve as a platform for research activities carried out within the institute, such as the characterization of the development of periglacial forms, evaluation of sedimentary transfers that take place on the slopes of the sudalpine valleys and the study of areas exposed to natural hazards.

Mendrisio geological sheet
Within the Switzerland geological Atlas in 1:25 000 scale, the Federal Office of Topography (swisstopo), has commissioned the institute the realization of the 1373/Mendrisio sheet under scientific coordination of Prof. Daniel Bernoulli. The activities include the geological detail survey on bedrock and quaternary formations, the elaboration of explanatory notes and geological profiles as well as the computerization of data and drafting of the final paper in vector format. The data acquired within this project will be used for the elaboration of a research project on the assessment of the geothermal potential of Mendrisio (Linda Soma Doctoral thesis) and for the definition of the stages of glacial retreat in the south of the Swiss Alps.
