Application of Spatial Priors in the Maximum Likelihood Classification of Tropical Dry Forest Classes by J. Ronald Eastman and Florencia Sangermano Introduction Over the past four years, the Southern Yucatan Peninsula Region (SYPR) Project has been engaged in an effort to develop a detailed mapping of tropical forest classes in the region of the Calakmul […]

 Environmental Modeling: Analyzing Motion with Trend Surface Analysis

Analyzing Motion with Trend Surface Analysis by J. Ronald Eastman TREND Generally speaking, GIS is not well suited to the analysis of phenomena that move. Analytical operations in GIS tend to focus on vertical relationships between layers. Further, it is sometimes very difficult to detect spatial movements. Figures 1 and 2, for example, illustrate areas […]
