Hexagonal Data Base Study.
Abstract
This is a final report for a study in the application of hexagonal data structures to handling geographic information. This report presents the results of an experimental software implementation utilizing hexagonal data structures applied to test data base. This report covers work performed during the second year of a study of data representation and processing. It is based on a coordinate system called GBT which addresses hexagonal regions in a plane. During the first year of the study, ISC software which uses the hexagonal scheme was tested on polygonal map data such as land use areas and flood plains. Results of the project are described in Hexagonal Data Base Study (September 1983). Portions of the theoretical discussion given in that report are included Chapter 2 of the current report. In the second year's work on this project we have incorporated raster imagery into the system. Line and point data were integrated with the polygon information. An extended query capability was added to handle these new data forms. The resulting enhanced system was tested on a small data set supplied by the U.S. Army Engineer Topographic Laboratories (ETL).
