Spatial Nutrient Management Planner 2.1
(SNMP-2.1)

Table of Contents

The Spatial Nutrient Management Planner is a decision support tool that facilitates the collection, analysis and presentation of spatial data related to nutrient management planning.

A new version, SNMP-2.0, was initially released on Oct. 24, 2008. An expanded version, SNMP-2.1, was released on Nov. 12, 2009.
The current release is 2.01.0014 released Nov. 20, 2009.

Attributes of SNMP-2.1 include:

  • Runs using the ESRI product ArcMap (either version 9.2 with service pack 6.0 or version 9.3).  You must have at least the ArcView license level of this software on your computer to run SNMP-2.x.  
  • Retains many of the features of SNMP-1.0 but organized in a completely new way.
  • Single version works in all states.
  • With a click of a mouse, data can be imported and exported from Purdue's Manure Management Planner.
  • Compatibility with NRCS Toolkit 9.x.

This is a beta version of SNMP-2.1.  Please let us know if you encounter problems. See Known Issues below, including prerequisites for installation.

More about SNMP-2.1.

Download SNMP-2.1. Version 2.01.0014 released Nov. 20, 2009.

Note: if you already have a version of SNMP-2.0 installed on your computer, you will need to manually uninstall it before installing version 2.1.

SNMP-2.1 provides more functionality than SNMP-2.0. The maps have been expanded, as well as the Zoom and View functions. Additionally, the Soil Test Data form from SNMP-1.0 has been recreated, allowing a cleaner data entry and importation of Soil Test data.

Please email John Lory if you want to be notified when we release updates of the software.

SNMP-2.0 Tutorials.  Step-by-step tutorials on how to load SNMP-2.0 onto your computer, access needed spatial data, use the program to delineate farm fields and setback features, make farm maps and export data to Purdue's Manure Management Planner.

Note: if you have any issues with SNMP-2.1, you can uninstall it and reinstall SNMP-2.0 if you wish (but please let us know your problems so we can fix them):

Other Key SNMP Links: (top)

Nutrient Management Data Download.  Links to University of Missouri sites that provide spatial data needed by SNMP-2.x.

National Setbacks Database.  SNMP-2.x includes a database of state-specific setback requirements for manure application. This site provides access to the regulatory and NRCS setback requirements in the 34 states we fully support.  It is up to the planner to insure that the setbacks SNMP are correct for the plan they are developing.

SNMP-1.1.  We no longer support SNMP-1.1 (released April 5, 2005) but it can still be downloaded from this site.  To run SNMP-1.1 you must have ArcView 3.x on your computer.

Known Issues: (top)

  • Not CCE certified for NRCS employees.
  • If you install MMP while ArcMap is open and have problems accessing MMP through the SNMP tools, then try closing and re-opening ArcMap.
  • Important: For SNMP-2.x to work you must have:
    1) .NET 2.0 (installing .NET 3.0 and 3.5 should install 2.0 also),
    2) ESRI's ArcGIS 9.2 (and service pack 6) with the ArcView license level or higher of ArcMap, or ArcGIS 9.3 with the ArcView license level or higher of ArcMap, and
    3) .NET support installed with ArcGIS.
  • If you do not uninstall SNMP-2.0 before installing SNMP-2.1 you will get the following message:

    .
  • There are prerequisites for SNMP installation (listed above). Without these, you may see the following (or similar) error:
    If you see this message, look in your ArcGIS installation folder (e.g. c:\program files\arcgis) for a folder called "DotNet". If this folder is not present (or is empty), then .NET support was not installed for ArcGIS on your computer. Follow the instructions here to install .NET support: http://support.esri.com/index.cfm?fa=knowledgebase.techarticles.articleShow&d=34178, then install SNMP.

    If the folder is present, verify that you have .NET 2.0 and ArcGIS 9.2 with at least service pack 6 or ArcGIS 9.3 installed. If you still have problems, contact us. These checks will be made automatically starting with version 2.0.0026.
  • Labeling is rather complicated in ArcMap. SNMP cannot address all scenarios and you may need to adjust the settings for the various layers to achieve your desired results. Be aware that annotation groups are used in the pre-defined maps (access them through the data frame's properties).
  • One-sided setback creation on line features may cause unintended buffers due to the algorithm used, particularly on lines that curve at the ends. You may need to split the feature into two or more features to get what is desired.
  • Since all setback features are stored as polygons, when creating one-sided setbacks on line features, SNMP tries to recreate the line from the polygon (the polygon is very skinny, so it only looks like a line). Occasionally the line is pointed in the wrong direction, and you may need to switch the buffer option from right to left or vice versa. This may also happen when editing the setback shape, so do the option switch last.
  • Please be aware that MS Excel 2007 does not support dbf format which may affect how you use the soil test data importing functions.

Version info (SNMP-2.1): (top)

  • Version 2.01.0014 cleans up some details with data entry and validation on the Field Data form. Ratings maps retain graphics when switching views and units have been added. Estimated CEC values are updated more regularly. Setbacks have been given rounded ends.
  • Version 2.01.0011 provides more functionality than SNMP-2.0. The maps have been expanded, as well as the Zoom and View functions. Additionally, the Soil Test Data form from SNMP-1.0 has been recreated, allowing a cleaner data entry and importation of Soil Test data.

Version info (SNMP-2.0): (top)

  • Version 2.00.0026 provides a more robust prerequisite check and provides information as to what is missing.
  • Version 2.00.0025 removes the automatic resetting of map layout elements when switching to layout view. Resetting all elements is available by re-creating the map using the SNMP menu options.
  • Version 2.00.0024 fixed some installation issues and connectivity issues with MMP.
  • Version 2.00.0023 fixed some issues with the setback tool, one of which caused the program to crash.
