Pegger collage

Pegger is an ESRI Arcview Extension to help foresters and forest engineers with initial road planning and design. Pegger was developed by Luke Rogers of the University of Washington's Forest Engineering Department in pursuit of a masters degree. Pegger was funded by the Rural Technology Initiative to help small forest land owners with forest management.

Pegger is designed to assist the landowner in the intial design of forest roads. Using a contour theme Pegger can "peg in" a road from any point on the landscape at any grade. Pegger allows for quick analysis of alternative road designs in a GIS environment where other analysis tools can assist the planner in making educated decisions about road location. Pegger also assists in the editing of existing road themes by making available merge and spline functions to combine and smooth existing road data.

New functionality added to Pegger!

Version 3.0.2 of Pegger for ArcView 3.x is now available for download. The user interface for Pegger has been completely redesigned with more intuitive controls and features and additional functionality. Pegger can now digitally survey a pegged road for export to the popular forest road engineering software RoadEng®. New features include:

  • Ability to store road name and grade information in the attribute table while pegging
  • New toolbar to enter road name information and change pegging grade
  • New setup dialog with streamlined user interface
  • Dissolve function to combine contiguous segments of road with similar features (like grade)
  • Improved help documentation, fully integrated into ArcView help
  • Improved installation program for easier setup
  • New survey p-line function to "digitally survey" a pegged road for export to RoadEng.
  • Tutorial data is included to help get started with Pegger
