CRSTransformer

class CRSTransformer

Bases: ABC

Transforms map points in some CRS into pixel coordinates.

Each transformer is associated with a particular RasterSource.

__init__(transform: Optional[Any] = None, image_crs: Optional[str] = None, map_crs: Optional[str] = None)

Parameters

• transform (Optional[Any]) –

• image_crs (Optional[str]) –

• map_crs (Optional[str]) –

Methods

__init__([transform, image_crs, map_crs])
map_to_pixel()	Transform input from pixel to map coords.
pixel_to_map()	Transform input from pixel to map coords.

__init__(transform: Optional[Any] = None, image_crs: Optional[str] = None, map_crs: Optional[str] = None)

Parameters

• transform (Optional[Any]) –

• image_crs (Optional[str]) –

• map_crs (Optional[str]) –

map_to_pixel(inp: Tuple[float, float]) → Tuple[int, int]

map_to_pixel(inp: Tuple['np.array', 'np.array']) → Tuple['np.array', 'np.array']

map_to_pixel(inp: Box) → Box

map_to_pixel(inp: Window) → Window

map_to_pixel(inp: BaseGeometry) → BaseGeometry

Transform input from pixel to map coords.

Parameters

inp – (x, y) tuple or Box or rasterio Window or shapely geometry in pixel coordinates. If tuple, x and y can be single values or array-like.

Returns

Coordinate-transformed input in the same format.

pixel_to_map(inp: Tuple[float, float]) → Tuple[float, float]

pixel_to_map(inp: Tuple['np.array', 'np.array']) → Tuple['np.array', 'np.array']

pixel_to_map(inp: Box) → Box

pixel_to_map(inp: BaseGeometry) → BaseGeometry

Transform input from pixel to map coords.

Parameters

inp – (x, y) tuple or Box or shapely geometry in pixel coordinates. If tuple, x and y can be single values or array-like.

Returns

Coordinate-transformed input in the same format.
