Abstract

A digital image analysis system has been developed at the Remote Sensing Research Program, Space Sciences Laboratory, University of California, Berkeley. The system is based upon high speed random access semiconductor memory used in an interactive video display configuration. The primary use of the system is for remote sensing applications and, as such, has been designed for multi-sensor and multi-temporal data display. Control of all variables allows the system configuration to be tailored to meet almost any user's needs. The video memory is modular, allowing two different intensity resolutions. Individual mapping tables allow functions to be applied to data without changing original data values. A selected portion of a memory module may be scrolled and viewed alongside another module. Simultaneously, a pseudo-color representation of a third or fourth module could be displayed and used in the image analysis process. Two types of cursors aid in object delineation and can be used to direct a module to module feedback operation for "quick look" manipulation of data. These system capabilities will be described and an example using Landsat data presented.
