833 A Feature-Based Geographic Information System Model
E. Lynn Usery

A conceptual model including spatial, thematic, and temporal dimensions for structuring features in geographic information systems is presented. 

839 A GIS-Based Statistical Method to Analyze Spatial Change
Joel D. Schlagel and Carlton M. Newton

Each measurement occasion is mapped as a separate GIS coverage; then, using a raster GIS, a non-para-metric test for trend is performed on a per-pixel basis across the collection of coverages. 

845 Using Public Domain Geostatistical and GIS Software for Spatial Interpolation
C. Varekamp, A.K. Skidmore, and P.A.B. Burrough

Public domain software for GIS and geostatistics were obtained from the Internet, linked together, and used to demonstrate the interpolation of soil variables. 

855 A Regional Information System for Environmental Data Analysis
B.H.C. Cheng, R.H. Bourdeau, and B.C. Pijanowski

A prototype software tool that supports access to and understanding of diverse environmental information is described. 

863 Development of a Geographic Information System for Urban Watershed Analysis
R.G. Greene and J.F. Cruise

Basic data layers are digitized into a spatial database, the system topological data structures are used to generate feature attributes and data products necessary for modeling, and coordinate values of features in the watershed are used to directly calculate flow-plane geometry and routing distances of overeland flow paths, gutters, and storm sewer segments.
