Abstract:

There often exist contradictories between different sea uses at adjacent sea areas. So it is needed to carry out an automatic method to detect the sea use change based on the marine functional area classification and marine environmental protection requirement in China. According to the sea water quality standards of the marine functional zones, this automatic detection method firstly computes the different values of distance and time between any two classifications of the above water quality standards, then establishes the buffer detection algorithm and the historical sea use detection algorithm between them respectively. The buffer detection algorithm could detect two different types of sea use in the same time but the different spatial places, then judging whether there are contradictories between these two types. The historical sea use detection algorithm could detect two different types of sea use in the same spatial place but the different times, then judging whether there are contradictories between these two types. Based on the above two detection algorithms, Microsoft Visual C# and the geographic information system development component ESRI ArcGIS Engine, the automatic detection function of new marine parcel adding and original marine parcel changing has been built. At last, we took Shanghai marine function zoning data as a case, and proved that as one of the core functions of marine cadastral spatial information management system, this method can realize automatic detection function of sea use.
