stilt.config.Grid.from_geometry#

classmethod Grid.from_geometry(geometry, *, cells_per_target=4.0, projection=None, max_cells=50000000)[source]#

Return a grid fine enough to resolve the cells of a geometry.

The bounds are the geometry’s extent, rounded outward to whole cells. The cell size is the smallest geometry cell width divided by cells_per_target, rounded down to one significant figure.

Parameters:

  • geometry (Mesh, Zones, or Grid) – Geometry to resolve. Any object with bounds, min_cell_width, crs or projection, and is_longlat.

  • cells_per_target (float) – Grid cells across the smallest geometry cell.

  • projection (str | None) – Projection of the grid. Defaults to the geometry’s CRS; the geometry is reprojected when they differ.

  • max_cells (int) – Warn when the grid would have more cells than this.

Returns:

The derived grid, with longitude/latitude bounds.

Return type:
