Field Boundary Buffer

This tool takes an existing field boundary and physically grows or shrinks it by a distance you choose, producing a new, adjusted boundary.

A recorded boundary often leaves too little room inside it for different machines, because equipment has physical dimensions outside its working area (turning, headlands, trailing implements, obstacles). An adjusted polygon, smaller or larger than the original, lets you plan for that clearance. Interior polygons (obstacles, wetlands, buildings) are handled together with the exterior boundary.

Note: the original boundary's accuracy may not be perfectly preserved by this process. Check any attributes in your file that may indicate the source recording GPS accuracy (for example fix type, HDOP, or differential correction source).

Disclaimer. You are responsible for the accuracy of any output file created with this tool and for verifying that it does not cross any obstacles. Using this tool means you assume all responsibility and liability for its accuracy and for any issues that occur from using the tool and its exported files. The developer assumes and accepts no responsibility or liability.
