Land Use Type Priority Oriented Layers Automated Clipping in GIS System

Along with the increasing information and intellectualized management requirements of land and resources, operations for assigning new attribute values to fields while clipping layers are more frequent in actual business. It is a practical problem that how to deal with the sliver polygon with high efficiency, high quality and sustainability. In this paper, based on the current research on the fusion processing method of sliver polygons, combined with the characteristics of land use data and related constraints, from the point of view of the geographical configuration priority and spatial similarity, design a set of clipping processes about land use layers based on geographical configuration prioritization and spatial similarity. While ensuring the high precision and high quality of the layer clipping, the land configuration priority is incorporated into the spot fusion constraint conditions. Finally, an improved automated clipping method that takes into account the preferential allocation of land types is applied to land use layers. The experiment verifies the practical feasibility and effectiveness of the method.
