Finding the Best Locations Using Suitability Modeling
Suitability modeling is one of the most common types of modeling performed in GIS. Suitability models are used to answer questions such as where to site a housing development, which locations are most preferred by deer, or identify areas most at risk during a fire. This session will guide you through how to create a suitability model using a variety of approaches while focusing on the weighted overlay technique, explore how preferences and weights are assigned, and discuss problems commonly encountered.

Suitability Modeling and Cost Distance Analysis Integrated Workflows
In this demonstration we will develop a management plan for bobcat. We will use suitability modeling to identify the best habitat patches for bobcats. Then, we will use cost distance analysis to connect these patches with the optimum network of wildlife corridors.

Wed, July 12 4:30pm – 5:15pm Demo Demo Theater 07

Distance Analysis

Identifying the Best Paths with Cost Distance Analysis
Cost distance analysis can be used to create corridors between a series of wildlife habitat patches, locate a road to a new development, or determine the best way to reach an injured hiker. This session will guide you through the basics of creating a raster cost surface, how to produce least-cost paths between sources, and we will introduce a new tool that connects a series of sources with the optimum network of paths.
