| Abstract: | This paper did an evaluation of the location accuracy of the Mapping Satellite-1 Three-Line-Array(TLA) image with and without control points. The experiment data involves several test blocks and a lot of fi eld surveyed GPS control points. The result showed that the horizontal accuracy of TLA image can reach 12 m and the height accuracy can reach 10 m without GCPs. When using GCPs, the accuracy can reach eight meters and three meters respectively which can satisfy the accuracy requirement of 1:50000 mapping. |
