Abstract: With the emergence of low-cost, high-performance graphics workstations, and database technologies, it is envisioned that Geographical Information Systems (GIS) will evolve from the simple vectorized map display/query systems to a system which provides a seamless integration of several functions. These include graphics, imaging, and analysis of multi- dimensional data, along with data handling schemes capable of accessing spatial and attribute data. In this report we focus on the imaging needs for such a GIS system. A class of imaging functions specific to GIS was implemented on HP workstations. This work is intended to serve as a basis for deriving a set of functional specifications for image/graphics processing in workstation-based GIS systems.
