A Study on the Application of the ZY3-03 Satellite for Mid-Scale Basic Geographic Information Updates
To explore the application potential of Resource Three No.03 Satellite in the update of basic geographic information data,this paper selected a city in Guangdong Province as the test area.By using the original stereoscopic survey image data and ground control data pro-vided by Resource Three No.03 Satellite,and applying photogrammetric techniques,different combinations of stereoscopic image pair models were constructed.Based on this,the accuracy of basic geographic information products such as digital orthophoto images,digital elevation mod-els,and digital line drawing maps generated by Resource Three No.03 Satellite was evaluated.The test results show that Resource Three No.03 Satellite can provide high-resolution,wide-coverage data,effectively meeting the accuracy requirements of medium-scale geographic information data products at scales of 1:25000 or 1:50000.
