environmentaltools.spatiotemporal.raster.obtain_geometry(contour, info)

Convert a contour represented by pixel indices to a real-world geometry.

Maps a sequence of (row, col) pixel indices from a raster contour to real-world coordinates using the x and y coordinate arrays provided in the info dictionary. Returns a LineString geometry representing the contour in spatial coordinates.

Parameters:

• contour (np.ndarray) – Array of shape (N, 2) containing (row, col) pixel indices of the contour.

• info (dict) – Configuration dictionary containing coordinate arrays under info[‘coords’][‘x’] and info[‘coords’][‘y’].

Returns:

geom – LineString geometry representing the contour in real-world coordinates.

Return type:

shapely.geometry.LineString
