IRS-P6卫星在土地利用动态遥感监测中应用的潜力分析

摘要: 为探索新的数据源, 研究了IRS-P6卫星在土地利用动态遥感监测项目中的应用潜力并进行分析, 就IRS-P6 影像在最大成图比例、最小响应图斑面积、地类可解度、地类解译精度等方面进行试验, 通过试验并根据土地利用动态遥感监测项目的技术要求可知, IRS-P6 卫星影像可以用来制作1∶2. 5 万、1∶5 万等中等比例尺的图件, 更新或者辅助更新1∶2. 5 万、1∶5 万的土地利用现状图, 在土地利用动态遥感监测中有一定的应用潜力。

Potential Analysis on the Application of IRS-P6 to Landuse Dynamic Monitoring

For to search new dataset, we study the application potential of IRS-P6 images in Landuse Dynamic Monitoring project. The resolution of IRS-P6 PAN image is 5. 8m. So it should can be used in this project. This paper tests some factors of IRS-P6, including the scale of cartography, the polygon area of response, the degree of recognising landtype, the precision of detecting information etc.Considering the demand of the project of landuse dynamic monitoring, the result indicates that IRS- P6 can be used to make a map of 1∶25 000 or 1∶50 000 and update or assistantly update 1∶25 000 or 1∶50 000 land use actuality map. In the landuse dynamic monitoring project, IRS-P6 image can be used as another dataset with LANDSAT and SPOT. So it can serve land management more rapidly.
