Recent advances in digital airborne sensors and satellite platforms make accurate, high-resolution multispectral imagery readily available. This opens the door to a host of new applications that address and solve old problems. However, traditional classification and application methods are often inadequate to produce useful information products from these new data sources. High-resolution imagery is particularly well suited to urban applications. Previous data sources (such as Landsat TM) did not show the spatial detail necessary to provide many urban planning solutions. One important urban application that is now possible due to the availability of high-resolution data is storm water management. This presentation paper will provide an overview of the new techniques developed to create an accurate map of pervious/impervious surfaces from high-resolution imagery for the City of Scottsdale, Arizona. A key component of developing techniques for new data is determining the level, and requirements of integration with GIS. This paper will review the opportunities and issues involved with integrating these new data sources and analysis techniques with the developing ArcView platform.
