5 Managing of landslide monitoring system and permanent GPS network ione della rete di Controllo dei Movimenti Franosi e della rete di stazioni GPS perman Novalesa, Rocciamelone landslide, 2010

6 Using remote sensing data for comprension of geological processing Sampeyre, Novalesa, Puy Rocciamelone landslide, 2009 landslide, 2010

7 What kind of data we manage Complex geographic data (vector) CARG (geological maps) SIFRAP (landslide inventroy) SICON (alluvial fan inventory) MZS (Microseismic Zonation)

8 Complex Symbology

9 Complex Geometry

10 What kind of data we manage Simple geographic component with lots of numerical data RERCOMF (Landslide Monitoring System); Geotechical inventory; PsinSAR data.

11 RERCOMF (Landslide Monitoring System)

12 A lot of sites with few instruments and manual reading Few sites with more instruments and automatic reading

13 RERCOMF (Landslide Monitoring System) 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'

14 S1-ERS2 (period ) out 2.2 milions of Permanent Scatterers PSinSAR DARSAT (period ) out 1.8 milioni of Permanent Scatterers SMO-SKYMED (period ) er 17 milions of Permanent Scatterers Over 200 millions of TS data Arpa La Piemonte microzonazione sismica in Regione Piemonte con strumenti Open Source GFOSS - Ancona 6-7 novembre 2014

15 Remote Sensing Permanent scatterer data

16 The main solution GEODATABASE! Cuneo R STAND-BY Torino RW MASTER Biella R DELAYED STAND-BY FTP/WEB Server Monitoring

17 The main solution GEODATABASE! Monitoring instruments ASCII format FTP Server Torino RW MASTER

18 Multiuser editing TORINO Real time data updating

19 Data interconnection 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

20 The main solution GEODATABASE! We try to automatise as much as as possible all repeating After geometry digitalization postgres derive the main sta PsinSAR movement data; Intersection with human artifacts that can interfer with landslide Other data such as borehole, moniitoring system, landuse, rain data ec

21 The main solution GEODATABASE! Pro Cons GIS multiediting; Flexibility; Easy to use; Power spatial analysis; Multiple installation; Replica; Well documented Raster management
