class polar2grid.core.containers.GridDefinition(*args, **kwargs)[source]¶

Bases: dict

Projected grid defined by a PROJ.4 projection string and other grid parameters.

Required Information:

grid_name: Identifying name for the grid
proj4_definition (string): PROJ.4 projection definition
height: Height of the grid in number of pixels
width: Width of the grid in number of pixels
cell_height: Grid cell height in the projection domain (usually in meters or degrees)
cell_width: Grid cell width in the projection domain (usually in meters or degrees)
origin_x: X-coordinate of the upper-left corner of the grid in the projection domain
origin_y: Y-coordinate of the upper-left corner of the grid in the projection domain
