SNAP for ArcGIS (hereafter referred to as SNAP) is a collection of Visual Basic for Applications (VBA) macros developed to streamline scheduling and transportation planning for timber harvest areas. Using modern optimization techniques, it can schedule timber harvest up to three time periods with consideration of harvesting costs, multiple products, alternative destinations, and transportation systems. SNAP attempts either to maximize net present value (NPV) or minimize discounted costs of harvesting and transportation over the planning horizon while meeting given harvest volume and acreage constraints. Developed using ArcObjects with VBA, SNAP works in the ArcGIS environment and provides an easy-to-use analytical toolfor sophisticated spatial planning of timber harvest.

ArcSNAP is an add-in for ArcGIS developed by Woodam Chung for the Forest Service.
