GMS:Interpolation Commands
Once a 3D interpolation scheme has been selected and the appropriate parameters for the selected scheme have been input, the dataset of the active scatter point set can be interpolated to another object. During the interpolation process, a new dataset is constructed for the target object containing the interpolated values. A separate interpolation command is provided for interpolating to each of the target objects. The interpolation commands are found in the Interpolation menu. The commands are as follows:
- Interpolate → Active TIN
The Interpolate to Active TIN command interpolates to the vertices of the active TIN.
- Interpolate → 2D Mesh
The Interpolate to 2D Mesh command interpolates to the nodes of the 2D finite element mesh.
- Interpolate → 2D Grid
The Interpolate to 2D Grid command interpolates to the 2D finite difference grid. The interpolation is done either to the grid nodes or to the grid cell centers depending on whether the grid is a mesh-centered or cell-centered grid. (See 2D Grid Types)
- Interpolate → 3D Mesh
The Interpolate to 3D Mesh command interpolates to the nodes of the 3D finite element mesh.
- Interpolate → 3D Grid
The Interpolate to 3D Grid command interpolates to the 3D finite difference grid. The interpolation is done either to the grid nodes or to the grid cell centers depending on whether the grid is a mesh-centered or cell-centered grid. (See 2D Grid Types)
- Interpolate → MODFLOW Layers
The Interpolate to MODFLOW Layers commmand lets you interpolate from 2D scatter data to MODFLOW data: top and bottom layer elevations, LPF array data (HK, VK, etc), recharge.
- Gaussian Simulation Options
Gaussian Sequential Simulation (GSS) is a form of Kriging that can only be used for 2D interpolation and only works when interpolating to 3D cell-centered grids.
- Jackknifing
3D Jacknifing identical to 2D Jacknifing.
When one of the interpolation commands is selected, the Interpolate dialog appears.
