The Improvement Of Digital Image Classification Over An Urban Area: A Probabilistic Relaxation Approach, Yafei Lu Dec 1989

The Improvement Of Digital Image Classification Over An Urban Area: A Probabilistic Relaxation Approach, Yafei Lu

Student Work

Digital image classification is a technique to extract land cover information from imagery using certain classification schemes. Additional information, either in a map, digital or verbal format, from multi-sources other than satellite imagery can be integrated into a classification scheme to improve its performance. The research in this field is essential because data interpretation has long been a weak link between the functions of two powerful systems: data acquisition by the remote sensing system and data storage, renewal and retrieval by the geographic information system - that has been more and more involved in the geographical research with the development …


An Improved Method Of Assigning Spatial Characteristics In A Raster Environment, Richard A. Benack Apr 1989

An Improved Method Of Assigning Spatial Characteristics In A Raster Environment, Richard A. Benack

Student Work

This thesis will attempt to develop an improved method of handling spatial characteristics in a raster GIS environment. The possibility of assigning multiple variables to a single location in a raster map will be explored. This will be done by developing a non-traditional Geographic Information System (GIS) called the Advanced Raster Analysis Subsystem (ARASS). ARASS will constitute one stop in the continuing evolution of GIS.
