The Image Interpreter Tool was designed to allow users to easily identify point locations overlaid on high resolution imagery into general vegetation or ground cover types in a repeatable fashion. This tool mimics field sampling methods (i.e., line point intercept) using remotely sensed data and “virtual” points along transects.
Image Interpreter has two main components: a calibration procedure (including training and testing modes) and a data interpretation procedure. Both components utilize a simple to use and intuitive interface for users familiar with ArcMap 9.3.
The training mode is designed to teach the user to correctly identify each ground cover type and provide training on the basic mechanics of tool. Testing mode evaluates how well a user can identify cover types by comparing individual results to a training dataset. Individual users ability to identify ground cover can be calibrated using these procedures to ensure repeatability among many users or project trials.
