HyperMap: a geographical information system for imagery and text storage and retrieval

摘要

aphical information system for storing and retrieving imagery and text data is described. The system provides a flexible means for attributing geographical features using full- text indexing and retrieval techniques. It integrates content- based and spatial data access methods into a single environment. The system is easy to use and involves no programming on the part of the user. All data is stored in standard Macintosh PICT and ASCII file formats. The system represents a low cost means of storing and accessing imagery and text data for remote sensing and GIS applications on a standard color Macintosh with hard drive.
