Highway Interchanges, Transportation And Land Use: An Exploration Of Changes In Transportation Volumes And Land Use Factors Within Interchange Catchments, Matthew Hampton

Geography Masters Research Papers

Highway interchanges provide the interface for and moderate access to the surface street system and help control congestion. Understanding the relationship between land use and transportation near highway interchanges can help to direct resources where they are most needed to maintain the integrity of the adjacent road system. This paper characterizes and ranks highway interchange areas in the Portland, OR Metropolitan Planning Organization (MPO) area with respect to changes in traffic volume and determines what factors are associated with these impacts. This study compares the transportation, population and land use patterns around 78 highways and freeway interchanges over two time …

Methods For Correcting Topographically Induced Radiometric Distortion On Landsat Thematic Mapper Images For Land Cover Classification, David Michael Rosen

Geography Masters Research Papers

Satellite imagery is commonly used to study land-use, land-cover change in mountainous areas. Classification of land-cover types is particularly difficult in this type of terrain because topography affects the spectral response of surface features. Several techniques have been developed to help compensate for this topographic effect and to increase classification accuracy.

The purpose of this study is to compare topographic correction methods to determine which produces the most accurate results. Method 1 does not use any topographic correction, serving as a control. Method 2 is based on the Lambertian model, and uses topographical data as variables in an equation. Method …
