stilt.config.Grid

class stilt.config.Grid(*, xmin: float, xmax: float, ymin: float, ymax: float, xres: float, yres: float, projection: str = '+proj=longlat') → None

Footprint grid: longitude/latitude bounds, cell size, and projection.

The bounds are always longitude/latitude. With a projected projection, the grid covers the bounds’ extent in that projection and xres and yres are in its units.

Parameters

Parameter	Description	Default
xmin	Western edge, in degrees longitude.	Required
xmax	Eastern edge, in degrees longitude.	Required
ymin	Southern edge, in degrees latitude.	Required
ymax	Northern edge, in degrees latitude.	Required
xres	Cell width in projection units (degrees for longlat, meters for UTM).	Required
yres	Cell height in projection units (degrees for longlat, meters for UTM).	Required
projection	Projection of the footprint grid, as a PROJ string. Particles and bounds are projected to it before gridding.	'+proj=longlat'

Methods

from_geometries(geometries, **kwargs)	Return one grid that resolves several geometries.
from_geometry(geometry, *[, ...])	Return a grid fine enough to resolve the cells of a geometry.
to_xarray()	Return the grid as a CF-1.8 dataset of cell centers.
