Calculate Linearly Interpolated Value dialog

The Calculate Linearly Interpolated Value tool is accessed by double-clicking on "ArcGIS Tool icon.png Calculate Linearly Interpolated Value" under the "ArcGIS Toolset icon.png Tables" toolset under the "ArcGIS Toolset icon.png MODFLOW Analyst" toolset under the "ArcGIS Toolbox icon.png Arc Hydro Groundwater Tools" toolbox.

This dialog calculates values in a target field based on a linear interpolation along a line feature. The tool is based on the Unique ID-SourceID relationship between MODFLOW instances (rows in a MODFLOW table) and line features. Such instances are commonly created using the Lines to MODFLOW tool, which creates instances in a MODFLOW table based on the spatial intersection of line features and Cell2D features, and also populates the SourceID and LinearScale fields of the target table.

The following fields are available. Required fields are marked with a ArcGIS required - green circle icon.png icon. Fields marked with a ArcGIS Error icon.png icon may either not be supported or the table doesn't exist.

  • ArcGIS required - green circle icon.png Input Line Features – Click the ArcGIS Browse button.png button to bring up the Input Line Features dialog in order to specify the input line features.
  • ArcGIS required - green circle icon.png Unique ID Field – Select the Unique ID of the input lines (e.g., HydroID) from the drop-down.
  • ArcGIS required - green circle icon.png Start Value Field – Select the start value to be used in the linear interpolation.
  • ArcGIS required - green circle icon.png End Value Field – Select the end value to be used in the linear interpolation.
  • ArcGIS required - green circle icon.png Target MODFLOW Table – Click the ArcGIS Browse button.png button to bring up the Target MODFLOW Table dialog in order to specify the target MODFLOW table.
  • ArcGIS required - green circle icon.png Target Field – Select the field in the target table where interpolated values will be written.
