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.
