Task has covered the survey of damages and the co-ordination of civil engineering. The time has been tight so fast and effected work being needed. A full GIS technology has been applied. First the damaged properties have been recorded on digital maps. Than a digital terrain model is generated and the flood level being indicated, too. As a coverage the map of settlement has been overlaid. The subsurface water level has been detected and put on the DTM coverage. Finally multi parametered maps have been printed and the planner could work on them easily.
