Abstract
An ArcView GIS Extension for Interpreting and Delineating Features in Georeferenced ImageryTrack: Application Development
Author(s): Ken Buja, Matt Kendall
NOAA's Biogeography Team has developed an ArcView extension to simplify the task of delineating features from georeferenced imagery with heads up digitizing. It allows a user to define a new classification scheme, load a previously saved scheme, or make modifications to an existing scheme. The extension creates a shapefile containing the necessary fields for the classification scheme attributes with the click of a button. The extension contains tools to add, append, and split polygons, which are attributed with a classification type selected with dialogs. Additional tools set a minimum polygon size and scale restriction for digitizing.
