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
