GISWorks Advanced Editing Extension
an extension developed initially for assessment professionals, enhances the editing capabilities for any ArcGIS user desiring advanced ArcInfo editing functionality in an ArcView environment. Users with "survey accurate" data in their GIS can also benefit from the included Lot Builder and Traverse tools. The Lot Builder splits blocks (4-sided polygons) into lots based upon front and back widths. The Traverse tool allows users to create features based on survey data or using the advanced curve and deflection methods of editing.
