Abstract
Impermeable Surface Analysis Using IKONOS Satellite Image
Track: Remote Sensing Imagery
Author(s): David Yun
In preparation of National Pollutant Discharge Elimination System (NPDES), the City of San Luis Obispo, California performed impermeable surface analysis with IKONOS multi-spectral satellite image using ERDAS IMAGINE, ArcGIS 8.1, and ArcView 3.2a. Vegetated areas are delineated using NDVI modeling. Combination of supervised and unsupervised classifications determined impermeable areas. City limit area is divided into various land use types, and they are overlaid with impermeable data. Percent impermeable areas are calculated for each land use types. Results are field checked.
