The NatureServe ERT.tbx (toolbox) should be used to package data for submission to NatureServe for use with the Environmental Review Tool. The purpose of the tool is to facilitate the process as well as provide the data in a standard and consistent way to the Development Team. 

The zip file contains the instructions, the toolbox, and a csv file which is required by the toolbox. The files generated by the toolbox will be created in the folder where the NatureServe_ERT.zip file is unzipped.

Following is a description of what the tool does:

  • Prompts for program. If your state is not listed in the tool selection dropdown, please provide us details about your native projection.

  •  Prompts for new and/or updated layers to be used for visualization and/or spatial calculation purposes.

  • Creates SpatialCalculations.gdb and VisualizationLayers.gdb, as appropriate, to contain the spatial and tabular data sets.

    • Projects spatial calculation layers to the projection identified within the ERT_Program_Projections.csv (ert_table), as provided in the NatureServe_ERT.zip file.

    • Projects visualization layers to WGS 1984 Web Mercator (auxiliary sphere)’ (WKID = 3857).

    • Creates frequency tables for use with the Feature Search tool, as indicated; the tables are added to the VisualizationLayers.gdb. Feature Search layers must be among the Visualization Layers as they are required to be included in the Map for Feature Search to work 

  • Requires each new Visualization layer to be included in an attached map (or map document - .mxd), which should be configured with appropriate symbology, field aliases, and visible fields.
  • Requires the layers within attached map documents be among the new layers.
  • Generates notes file indicating if layers are new/updated, for display/calculation purposes, and whether the layer should be restricted. An Additional Information area is left empty for each layer within the notes file to be manually populated as necessary.

  • Creates a zip file containing the resulting geodatabase(s), map document(s), and notes file.
