Landuse status investigation and analysis by multi-information technology for the development area

In this paper, QuickBird high resolution satellite image data, combined with the prior landuse maps, the landuse major planning map and other basic datum was adopted to extract landuse information of Nanchang Hi-Tech Industrial Development Area through the human-computer interaction approach, and the results were verified by plot in field to do meta-analysis. The results show that the multi-information method can objectively and accurately reflect the landuse types, structure and the degree of utilization in development area, and provide timely, accurate and detailed basic information for analysis of intensive landuse situation of national development area for the national macro-control.
