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.
