Subjective Judgment and Context

We have already touched on this in looking at natural variation. While some methods of data collection may appear highly objective (e.g., laboratory measurement of soil pH values from field sampling), the interpretation of what […]

Environmental Modeling within GIS

Once again we need to make the distinction between linking GIS with established environmental simulation models and being able to carry out some forms of environmental modeling within GIS using cartographic processing and/or map algebra-type […]

Initial Conceptualizations GIS

In broad terms, GIS have provided environmental modelers with an ideal platform for spatial data integration, parameter estimation, and cartographic visualization, while environmental modeling has allowed GIS profession als to move beyond simple inventory and […]

Environmental Modeling

Cluster Detection

This ex post approach is structured quite differently from the previous ones. The initial phase is predominantly exploratory of spatial patterns either by statistical or geocomputational techniques and, once an abnormal concentration of some effect […]

Coastal Oil Spill Modeling

Coastal oil spills are serious environmental disasters often leading to significant long-term impacts. From 1978 to 1995, there were in excess of 4,100 major oil spills of 10,000 gallons or more (Etkin and Welch, 1997). […]
