RS与GIS技术在土地利用更新调查的应用研究

The Application of RS and GIS to the the Updating Land Use Survey

在土地利用更新调查中,RS与GIS技术相结合具有快速、适时地采集、存储管理、更新、分析、应用数据的能力,为土地利用更新调查提供了坚实的技术支撑。以四川省土地利用更新调查项目为例,阐述RS与GIS技术相互结合在土地利用更新分类中的具体应用。

Taking updating land use survey in Sichuan Province for example, this paper deals with the application of RS （Remote Sensing） and GIS （Geographic Information System） to the updating land use survey. Land utilization and updating investigation is an important means that maintains the present situation of land use survey. Compared with the traditional methods, the application of RS and GIS enhances has the ability of information collection, memory management, data updating and analyzing, providing a solid technical support for land utilization and updating survey.
