PRODUCTION OF THE CADASTRAL GEODATABASE OF WATERS AND RIVER BASINS

The project involved the implementation of the regional hydrographic network information system. Using 3-D and network modelling, watershed and drainage areas were defined and river courses were classified according to the Strahler methodand according to SIBAPO coding.

The activities implemented are:

• Definition of operational methodology
• Importing existing data and normalising them
• Construction of the hydrographic grid graph
• Coding of river rods
• Construction of basins and sub-basins
• Application of river rod orders according to Strahler
• Classification of auctions using SIBAPO coding
• Quality control (geometry, topology, data control)

In the realisation of the hydrographic network graph, the following were verified/corrected:

• The elevation of the nodes and individual points constituting the geometry of the river courses
• Definition of the direction of water flow
• The coding of grid layers adhering to DBT specifications
