The measurement techniques for deformation detection usually employed by surveyors are based on the geodetic approach (such as total station and GPS).The data processing is usually consists of three separate modules:least squares estimation,deformation detection and graphical presentation.This paper describes a software system for 3-D deformation detection via geodetic methods,called GPSAD2000,currently being developed at CIMES.The main components of GPSAD2000 are:least squares estimation (LSE)of GPS baseline vectors,3-D deformation detection (via congruency testing)and graphical visualization.All these components are integrated in one environment using Visual Basic.GPSAD2000 runs under Windows operating system,is user friendly and has many on-screen facilities for presenting the results of deformation detection,both numerically and graphically.For graphic presentation,output from GPSAD2000 may be exported to formats such as *.dxf,*.jpg and *.bmp.Test results with known data are also included.
