This paper analyzed the investigation technology of county land use updated using quick bird satellite image and the choice of the fine resolution satellite information source ,and discussed the method of the image processing and the interpreting of quick bird satellite image by the practice of Xinjin county land use updating investigation.

Data error of land use change surveying based on SPOT5 remote sensed image was compared with that of detailed land survey in theory.

Design and realization of Suzhou database system for land use change survey;

Compared to aerial survey or the custom method, the high resolution images of SPOT5 make it cost-efficient for remote sensing-based land use change survey at a 1∶10000 scale.

Based on the fuzzy characteristic of the quality assessment of land use renewal investigation,this paper presents using fuzzy math theory to do the assessment.

Using GPS/PDA technique could improve the precision and efficiency of land use renewal investigation.

Based on some experiences about the land use renewal investigation for Anyang city using new technique,this paper points out the advantages of new techniques and the methods of integrating new and old techniques.

The land use right definition and area measure of present land-use renewal investigation must be strictly using administration location of boundary.
