Abstract
Integrating GIS Modeling and Remote Sensing Classification Techniques for Mapping Vegetation on U.S. Army BasesTrack: Remote Sensing Imagery
Author(s): Paul Loechl, Chad Hendrix, Wendy Goetz
The U.S. Army Corps of Engineers research laboratories have established guidelines for mapping vegetation on army installations to address land management issues on Army military bases. Pacific Meridian Resources has completed one of the first vegetation mapping efforts to follow these guidelines. A vegetation map of the Fort Hood Military Reservation in Killeen, Texas, was developed using one-meter scanned digital color infrared orthophoto quarter quadrangle (DOQQ) imagery. A series of unsupervised classification and modeling techniques were used to separate 16 land cover classes. A core component of the project was the development of an ArcView model to eliminate tree shadow areas during classification by utilizing the surrounding vegetation patterns. The integration of GIS modeling approaches with techniques for remotely sensing vegetation classification was a key component to the success of the project. A review of techniques, lessons learned, and issues will be presented.
