In order to enhance the efficacy of rapid extraction and analysis of urban ecological remote sensing indicators,this paper employs the secondary development mode of C#+GDAL open source library+ArcGIS Engine method library+database to devise methodologies and algorithms surrounding the pivotal concerns of remote sensing data processing,parameter extraction and result mapping in the extraction of urban ecological environment indicators.Subsequently,the GDAL open source library is utilized.The processing of raster and vector data is then achieved through the use of the GDAL open source library and database technology,which also facilitates the rapid extraction of NDVI,NDSI,WET,LST and other parameters,as well as the modelling and calculation of related indicators and the statistical analysis of related urban ecological indicators.The software realizes functions such as rapid connection of grid statistical data,construction of analytical models,statistical analysis and result mapping.It shows that the combination of GDAL,ArcGIS Engine,and DB can realize indicator calculation,grid analysis,classified statistics and other methods,thereby realizing grid-based spatial analysis of urban ecological environment,and providing effective technical support for urban ecological environment data management and rapid analysis.
