RockWorks | ModOps | Solid | Extract Grids | Depth to Target
Given a ground surface grid model and a solid model, this program will create and display a grid that represents the depth to either the solid node value greater than a specified minimum, or the depth to the shallowest node with a G value within a specified range.
Applications for the Depth to Target program include mining (e.g. depth to shallowest sand), geotechnical (depth to competent rock), petroleum (depth to hydrocarbon), hydrology (depth to water), and environmental (depth to contaminated water).
! This program requires that the solid model (.RwMod file) to be analyzed already exists, as well as a grid model (.RwGrd file) that represents the ground surface elevations.
Feature Level: RockWorks Basic and higher

Step-by-Step Summary
- Rules & Filters
Use these tabs at the top of the window to apply spatial filters or time/date filters to data being displayed in your map layers. (More info)
- Target
- Ground Surface Grid Model (Input): Browse for the grid model (.RwGrd file) that represents the ground surface elevations. This grid model can be generated using borehole tops in the Borehole Operations | Maps | Borehole Map (Surface Contours), from XYZ data in the datasheet (ModOps | Grid | Create | XYZ -> Grid), by importing an elevation model (Grid | Import), etc.
- Solid Model File (Input): Browse for the solid model (.RwMod file) that contains the Grade values to be processed.
! The grid and solid models must have the same X and Y extents and node spacing.
- Depth Grid Model File (Output): Click to the right to type in the name to assign to the output grid model (.RwGrd file), which will represent depth to target.
- Compute Depth to Largest Node Value >: Choose this option if the output grid is to represent depth to the first occurrence of a node value greater than a specified value. Enter that value into the prompt.
- Compute Depth to Highest Elevation Node Value ≥ __________ and ≤ _________: Choose this option if the output grid is to represent depth to shallowest node whose value is within the defined range.
- Create 2-Dimensional Grid Diagram: Insert a check here to create a 2D map of the output grid model. Click on this tab to set up the 2D map layers (bitmap, symbols, labels, line contours, color-filled contours, labeled cells, etc.).
! Don't request map symbols or labels if you don't have any data loaded into the RockWorks datasheet at this time.
- Output Options: Use these settings to define whether the output graphic is to be saved (or displayed as "untitled"), how the file should be named, and whether it is to be displayed after it is created. It also offers export options. (More info)
- 3D Grid Diagram: Insert a check here to create a 3-dimensional image of the output grid model. Click on this tab to set up the 3D map layers (surface style, colors, perimeter, reference cage, etc.).
- Output Options: Use these settings to define whether the output scene is to be saved (or displayed as "untitled"), how the file should be named, and whether it is to be displayed after it is created. It also offers export options. (More info)
- Select the ModOps | Solid | Extract Grids | Depth to Target menu option.
- Enter the requested menu item, described above.
- Click the Continue button to proceed.
RockWorks will read the input solid model and scan each vertical column of nodes. It will calculate the depth to the first occurrence of the node value greater than the specified minimum OR determine the shallowest node whose values are in the defined range. The resulting depths will be stored under the define output file name.
The requested diagram(s) will be displayed in a RockPlot2D tab and/or RockPlot3D tab in the Options window.
- You can adjust any of the settings via the main Options tab to the left, and then click the Continue button again to regenerate the grid and diagram(s).
- View / save / manipulate / export / print the diagram(s) in the RockPlot2D or RockPlot3D windows.
