Abstract

Abstract:

Based on spatial characteristics of forest land data,using the GeoSOT global subdivision grid,the study developed a set of global uniqueness,multi-scale and discreteness of spatial information coding location identification subdivision model to forest land data.Therefore,it solved the problems in multi-source multi-scale spatial data of woodland update management,such as unified regional organization,integrated management,statistical analysis and so on.In this study,we used Microsoft Visual Studio to develop a C/S architecture of forest-land data integration management experiment,to verify the effectiveness of the data based on the partitioned coding model in forest land data management,data transmission,and data applications.Experiment showed that,it can effectively organize and manage woodland data,improve the efficiency of data retrieval and access,and meet the business needs of forest land data management based on GeoSOT global subdivision grid.

Key words: GeoSOT model, forest land, data updating synchronization, integrated approach for organizing and managing multiple
