土地资源遥感调查中的空间信息多重采样框架设计与GIS实现

我国是一个地域广阔、资源类型多样、土地利用类型和土地利用结构复杂的国家，此外，我国又是一个发展中的国家，正处在工业化的过程中，土地资源的利用类型变化巨大，在进行全国范围的土地资源调查时不仅要考虑较高的空间分辨率，同时也要充分认识到在我国现阶段资源调查...

A Schema of Multi-layer Sampling Framer of Spatial Information in the Resources Remote Sensing Investigation and Application of GIS Techniques

Resources investigation, especially which over large areas, has many difficulties to cope with, and one of those is contradiction between the spatial scale and the time interval of the investigation. The paper focuses on a schema of sampling frame in the resources investigation that will shorten the time interval while keep the spatial scale. The multi-layer sampling of frame can be applied by GIS techniques and give efficient support to the resources investigation.
