Using Remotely Sensed Imagery to Determine Impervious Surface in Sioux Falls, South Dakota - (PPT)

摘要

Initial results demonstrated that by merging the spectrally detailed IKONOS image with the higher spatial resolution aerial photography creates an outstanding image to utilize for visual and programmatic classification. City Engineers commented on the impervious designations that they could make by analyzing the merged image manually or by utilizing it within other software. In addition, after classification, the image became even more useful. The advancements in high resolution satellite imagery and client technology provide local governments with a cost-effective solution to determine impervious and pervious surfaces as input to storm drainage fee calculations.
