Using remote sensing data for comprension
of geological processing
Complex geographic data (vector)
●CARG (geological maps)
●SIFRAP (landslide inventroy)
●SICON (alluvial fan inventory)
●MZS (Microseismic Zonation)
What kind of data we manage
Complex Symbology
Complex Geometry
Simple geographic component
with lots of numerical data
●RERCOMF (Landslide Monitoring System); Geotechical inventory;
●PsinSAR data.
What kind of data we manage
RERCOMF (Landslide Monitoring System)
A lot of sites with few instruments and manual readingFew sites with more instruments and automatic reading
Type number frequency
Manual instruments (Inclinometer, piezometers gps, ecc)
1'000 2 x year
Automatic inclinometers 50 1 every 8 hours
Automatic landslide GPS 6 1 every 30'
Atomatic geodetics GPS (quakenet) 6 1 every 30'

Real time data updating
TORINO
Multiuser editing
e.g. landslide studing needs to analyze a lots of different kind of data:
● Monitoring data
● Borehole and geotechnical data
● Hystorical and archive data
● Field survey infromation
Data interconnection
We try to automatise as much as as possible all repeating spatial analysis.
After geometry digitalization postgres derive the main statistics, eg:
●PsinSAR movement data;
●Intersection with human artifacts that can interfer with landslide
●Other data such as borehole, moniitoring system, landuse, rain data ecc..)
The main solution GEODATABASE !
Pro Cons
●GIS multiediting;●Flexibility;●Easy to use;●Power spatial analysis;●Multiple installation;●Replica;●Well documented
●Raster management

Spatialite
We need to interact with users that can't connect to our network
spatialite allow to share data with all power of a geodb:
●trigger,
●automated spatial analysis,
●wide data format,
●ecc...
Pro Cons
●Easy to use●Full integration with PG/PGIS●Advanced styling●Atlante●Powerful form editor●Python●Sharing instruments with external users
●Stability●Processing●Poor integration with spatialite
