摘要
以宁波市规划区高分二号卫星影像为数据源,在明确数据正射—融合预处理和大气校正预处理流程的基础上,对研究区内影像进行了批量预处理,并对结果进行了分析评价。结果表明,批量预处理后的结果能满足1∶10 000正射影像生产要求和获取较为准确的地表反射率信息,可为后续宁波市遥感应用提供基础数据。
In this study, taking GF-2 satellite images in the planning area of Ningbo City as data resource, based on the preprocessing flows of orthorectification-fusion and atmospheric correction, we realized the batch preprocessing in the study area. The results indicate that the batch preprocessing results can meet the needs of 1∶10 000 orthoimage production and obtain typical object reflectivity information, which can provide a basis for remote sensing applications in Ningbo City.
