The Prioritize Target Measure Application (PTMApp) is a geospatial watershed model that uses land use data, lidar derived hydro conditioned elevation models, soils, and travel time grids to develop source assessments of the fate and transport of sediment, phosphorus, and nitrogen across agriculture watersheds. This model also predicts appropriate geospatial locations for the placement of agricultural best management practices (BMPs) based on United State Department of Agriculture Natural Resource Conservation Service (USDA-NRCS) practice types as outlined in the <a href=https://www.nrcs.usda.gov/resources/guides-and-instructions/field-office-technical-guides target=_blank>Field Office Technical Guide (FOTG)</a>. The model also applies economic information to the practices to determine the overall cost effectiveness of implementing specific BMPs. The model is a toolbar add in that utilizes the ESRI Arc 10.X and Arc Pro software platforms and can be downloaded <a href=https://ptmapp.bwsr.state.mn.us/User/PTMAppDesktop target=_blank>HERE</a>. The data outputs from this model can be used at multiple scales and has been used for <a href=https://bwsr.state.mn.us/one-watershed-one-plan target=_blank>Comprehensive Watershed Management Plans</a> at the major watershed scale down to individual practice effectiveness at the field scale. Modeled geospatial data has been made available to the public through the deployment of the PTMApp web application, which is hosted by MnGEO at <a href=https://ptmapp.bwsr.state.mn.us/ target=_blank>THIS SITE</a>. In addition, technical documentation and training materials for PTMApp can be found at the Minnesota Board of Water and Soil Resources (BWSR) website <a href=https://bwsr.state.mn.us/ptmapp target=_blank>HERE</a>, along with a Story Map that provides an descriptive overview.
