Surveying and GIS activities on Engineering Planning
•Digital maps for general planning
•Settlement planning, multi criterion GIS analysis
•Effect studies, choosing among plan variants (modeling)
•Digital maps for planning, surveying network, digital terrain models
•3D views of planned object
Planning
•Data gathering from Land Offices, expropriation, occupying agricultural areas, etc.
Building (in process)
•Surveying network for setting out, setting out, geometric control of building
•Map for the completed object
•Change in Land Cadastre Register
•Deformation analysis, settlement analysis
•Operation supported by GIS, expert systems, supervisory system
Operation

Orthophoto
On field surveying activities•Planning and measuring of local surveying network
•Geometric control of building – setting out, in progress control
•Map for the completed object, control after building finished
•Deformation analysis, settlement analysis
Processing surveying observations
Co-ordinate calculation
•Intersection, resection, free station
•Traversing, network adjustment
•Orientation, detailed observations (polar)
Processing methods
•Built in software of total station
•General pupose software (Excel, Maple, Matlab, stb.)
•Special surveying software (GeoEasy, Leica Surveying office, …)
Recorded observations, Electric fieldbooks
RS-232
PCMCIA,SD card
Construction of digital maps
State of art Surveying Instruments
Direct reflex EDM
Laser beam
Electronic two axis level, compensator
Setting out light
360 deegre prism
