Since 2013.01. Csv file with cell centers. Csv file should contain an "x" and "y" column. The cell centers should be listed from the upper left to the lower right, row by row. For regular grids always try to use a regular grid with a (custom) geodatum. For config example see: 06Grids-ConfigExamples
netcdfFile
Since 2015.02. Reference to a UGRID NetCDF file that contains only grid geometry meta data. This only supports mesh topologies (unstructured grids) with 2D coordinates. This can be 1D network, 2D triangular, 2D flexible or 3D layered mesh topologies. This currently only works for files that are compliant to the UGRID 1.0 conventions.
