ACPF (Agricultural Conservation Planning Framework)

The ACPF watershed planning toolbox is intended to leverage modern data sources and help local farming communities better address soil and water conservation needs. High-resolution geo-spatial datasets that can improve the information base available for conservation planning have recently become available.

The Agricultural Conservation Planning Framework (ACPF) toolbox can be used within the ArcGIS® (Ver. 10.2 – 10.5) environment to analyze soils, land use, and high-resolution topographic data to identify a broad range of opportunities to install conservation practices in fields and in watersheds. These opportunities can then inform of a non-prescriptive approach to encourage farmers and landowners to become engaged in local watershed improvement. (2018)


ROOTEDGE is a computer program written for MS-DOS machines that measures areas, perimeters, lengths, and widths of objects in binary images. ROOTEDGE uses a new algorithm for perimeter measurement, the Edge Chord Algorithm, which is more accurate than older algorithms, and less affected by the orientation of the objects in the image.
