Ground Model

InfoWorks ICM supports the use of a ground model to represent the ground surface in the area covered by your hydraulic model. The ground model can take one of two forms:

  • a triangular irregular network (TIN), with the surface represented by triangles with known elevations at the triangle vertices.
  • a series of blocks of gridded ground model (Grid) data. The blocks are divided into cells of a particular resolution. The resolution must be uniform across a block, although different blocks can have different resolutions.
