Main activities WP3.a: Repeated GPS WP3.b: Continuous GPS WP3.c: Systematic interferometry analysis of incoming SAR images WP3.d : Modelling

Summary of geodetic activities (1) Permanent GPS stations renewed Re-observation of 60 GPS points in a 50km radius around Patras Installation of two GPS stations at UPAT (1 with real-time) Kinematic GPS in the Panagopoula landslide PS-InSAR studies Real-time GPS data broadcasted from TRIZ Kinematic GPS levelling

Summary of geodetic activities (2) ERS SAR data acquired in 3 different frame was processed with conventional InSAR and with PS techniques

Deliverables 8: Data base for continuous GPS √ 42: Deformation of the rift from GPS √ 43: Two new continuous GPS stations √ 44: Set of stable pixels for InSAR long term stability √ 45: Elastic models of the observed deformations √ 86: Evaluation of a daily kinematic GPS system on commercial railway traffic on road and landslide only 94: Modem for the new GPS stations √ 105: Web page updated with selection of continuous records and selected events from the GPS arrays √

D8: Data base for continuous GPS Raw data and time series of coordinates available on line

D42: Deformation of the rift from GPS A data base of GPS points was created to contain both the description of the points and the coordinates at all epochs of observations

D43: New stations - 2 new stations at Patras (one standard, one with real-time differential - 5 “old” stations renewed with new receivers Location of the CRL GPS stations and view of the LIDO station

D44: Set of stable pixels Conventional InSAR used ROI-PAC software PS-Insar studies used ROI-PAC post- processing and new algorithms developed at NOA Aigion area Itea area Map of Permanent scatterers (colours indicate quality of PS, low=green, high=red)

D45: Elastics models of the observed deformation

D86: Kinematic GPS 18 points accurately positioned in the Panagopoula landslide. Kinematic profile available for further studies and airphoto registration More kinematic GPS levelling performed by car

D94: Modem for the new GPS stations The two new GPS stations and TRIZ are accessible remotely via internet. - TRIZ broadcasts real-time data - PAT1 receivers real-time data and provides real-time differential coordinates Trizonia GPS receiver and web interface

D105: Web site for Geodesy in the CRL Information about GPS and InSAR work and results of 3HAZ at
