IdentityCRSTransformer

class IdentityCRSTransformer

Bases: CRSTransformer

Transformer for when map coordinates are already in pixel coordinates.

This is useful for non-georeferenced imagery.

__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(inp)	Transform input from pixel to map coords.
pixel_to_map(inp)	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)

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)

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.
