About Spatial Nutrient Management Planner 2.1

What does SNMP-2.1 do?


The Spatial Nutrient Management Planner (SNMP)is a decision support tool that facilitates the collection, analysis and presentation of spatial data related to nutrient management planning.  SNMP-2.1 facilitates and simplifies using the ESRI Geographical Information System (GIS) ArcMap 9.2 in developing a nutrient management plan.

Use SNMP to:

  • View and manage spatial data used in nutrient management planning.
  • Map field boundaries and automatically determine dominant soil type in each field.
  • Map local features such as the location of streams, wells, ponds, property boundaries and neighbors and automatically show state-specific manure application setbacks.
  • Program automatically calculates field size and spreadable acres (acres available for manure application).
  • Program facilitates making required maps including fields with setbacks map and soil type map.
  • Move spatial information from SNMP to Purdue's Manure Management Planner (MMP).

What are the system requirements for SNMP-2.1

  • ESRI ArcGIS 9.2 GIS software at the ArcView level or higher with service pack 6 or ArcGIS 9.3 at the ArcView level or higher.

  • The program runs within the ArcMap component of ArcGIS 9.2 or 9.3.   

  • Approximately 10 MB of hard drive space.  Additional space will be needed for spatial data layers such as digital orthophotoquadrangles (DOQQs). 

  • Screen capable of at least 800X600 pixel resolution.
