摘要
对于国家新推出的地理国情普查项目,卫星遥感数据作为其基础数据有着至关重要的作用,直接影响着目视解译的结果。本文主要对WorldView-2影像进行分析,并对其整个预处理的流程进行分析整理。最终表明,WorldView-2影像可采取辐射校正-几何校正-影像融合-数据正射纠正的技术路线对整个影像进行预处理,为地理国情普查项目中的影像数据预处理提供了参考及依据,为后续的目视解译过程奠定良好的基础。
For the country＇s new geographic conditions survey projects , satellite remote sensing data as its basic data have a vital role , directly affects the visual interpretation of the results .In this paper, we analyze the WorldView -2 images, and analyzes the process of pretreatment .Finally suggests for WorldView -2 radiation correction , geometric correction , image fusion images taken -data is correct technical route of the whole process of image preprocessing , the image data in geographic conditions survey project provides reference and basis of pretreatment and lay a good foundation for subsequent visual interpretation process .
