Abstract:

In order to seek a more convenient, fast, high accuracy map generalization solution, the author used the second development interface of ArcObjects component to come true the fast, effective and high efficiency shortening the map size of land use from 1:10000 to 1:50000 by use ArcMap soft based on county cultivated land resources management system construction project. It refers to two aspects, that is, small polygon aggregation and narrow features broken and merger. The result shows work efficiency increasing and precision improving, and these two aspects herein ensure the higher quality of map generalization of land use as well. It can be recommended as an important reference and good methods to realize the map generalization of land use from 1:10000 to 1:50000.
