General Specifications

In this section, by default, the Layer group name is Soil Survey Data, which can be changed by the user. Click the […] button beside the Shapefile path entry to specify the directory location to which to save the downloaded shapefiles.

Soil Survey Data Boundary Limits

In this section, choose one of the following three options for defining the geographic location:

  • Current screen limits: The software will use the Map View screen display as a boundary limit.
  • User-defined limits: The user can draw a rectangle on the Map View representing user-defined limits for the NRCS soil survey data to be downloaded. Click the [Pick] button to define the soil survey limits. The dialog box will temporarily disappear, and a message will be displayed on the status line. Click and drag a rectangular region to define the limits. After releasing the mouse, the user will be returned to the dialog box. A layer will be created with a rectangular box to represent the user-defined selected region.
  • Model extents: If a project model has been defined, this option will create a bounding rectangular region to the extents of the defined model, plus an additional buffer boundary.
