pydsstools.core.gridinfo.v6.structures

DSS Version 6 grid metadata ctypes structures.

This module contains the C-compatible structures used for DSS v6 grid I/O. These structures are used for binary serialization and interaction with the HEC-DSS C library.

Grid Type Codes

400/401: Undefined grid
410/411: HRAP grid
420/421: Albers grid
430/431: Specified grid

The even codes (400, 410, 420, 430) indicate time-varying grids. The odd codes (401, 411, 421, 431) indicate static grids.
