GIS Technology, 3D Models and Mathematical Models as a Tool for Assessing Development Capabilities of Flood Risk Land to Make Arrangements of Municipal Planning Documents

With regard to the municipal spatial policies, the issue of flood protection, and hence the directions of development of flood-endangered land seem rather significant, given the possible social and economic consequences of a wrong decision. Currently, there is no legal obligation, within the statutory activities of flood protection institutions, to implement guidance documents prior to the works on the municipality development. It is determined by the local government in the planning documents, which are in accordance with the applicable regulations, acts of local law. Space management, through planning development and land use or the landscape protection, requires the access to comprehensive and reliable information. GIS technology, 3D models and mathematical models using neural networks in spatial analysis and monitoring changes in space to protect flood risk land, give the possibility of collecting the information that constitutes the basis of knowledge on the area, which helps to make decisions regarding a purpose and a method of the land use. The data obtained in this way are a valuable source of knowledge on the stage of preparation of planning documents that determine the directions of municipal spatial development. Under the Act of 27 March 2003 on spatial planning and development [spatial planning and development act 2003], these documents are a municipal study of the conditions and directions of the spatial planning and a local zoning plan.
