| Abstract | The Earth Resources Observation Systems (EROS) Data Center has developed a prototype Remote Image Processing System (RIPS) which utilizes off-the-shelf microprocessor technology and a color raster refresh display. Although it was designed primarily for low cost interactive image analysis, the system is being evaluated for use in cartographic analysis and display tasks. Similarities and differences between RIPS-type raster refresh display systems, and minicomputer-driven graphics terminals which are commonly used to display cartographic data were investigated. It was determined that many traditional differences have been eliminated because (a) new cartographic analysis systems are often configured with raster refresh displays, and (b) image analysis systems have been programmed to accept and display cartographic data. In order to evaluate the applicability of RIPS for cartographic analysis tasks, representative spatial analysis algorithms were performed on RIPS and compared to a minicomputer with a graphics display. Tests included routines for point-in-polygon matching, line drawing or rasterization, spatial filtering, and image classification. Results indicate that many functions that have traditionally been relegated to larger machines can now be efficiently performed by microprocessor systems. Based on the results of these tests, optional RIPS configurations were defined for increasing spatial resolution (at the expense of spectral resolution), and for substituting faster Winchester type disk drives for lower cost floppy disks. Future versions of RIPS may also incorporate a coordinate digitizer and an electrostatic plotter. |
