Change Detection Workflows
Tuesday, October 27th
8:00 A.M. - Noon
Location: TCEQ Computer Training Lab
Performing the seemingly simple “change detection” is rarely simple, largely due to a poor understanding of the problem and non-realistic result expectations derived from available geospatial data and the multiple software applications required to process the data. The solution to this problem is to understand the required data inputs, the step-by-step workflow for specific end-users and how to implement a complex analysis in an intuitive process. In this interactive lecture workshop attendees will explore at least three different workflows to identify areas of change. Both image and vector data with will be used in workflows that consist of zonal likelihood, discriminate function and customized spatial modeling. These workflows will be executed using ERDAS IMAGINE remote sensing software.
