rastertodataframe.tiling module

Utils for reading a GDAL Dataset in small tiles.

rastertodataframe.tiling.tiles(ras, size=256)

Generator return a raster array in tiles.

Parameters:

• ras (gdal.Dataset) – Input raster.
• size (int) – Size of window in pixels. One value required which is used for both the x and y size. E.g 256 means a 256x256 window.

Yields:

np.ndarray – Raster array in form [band][y][x].

rastertodataframe.tiling.windows(ras, size=256)

Generator for raster window size/offsets.

Parameters:

• ras (gdal.Dataset) – Input raster.
• size (int) – Size of window in pixels. One value required which is used for both the x and y size. E.g 256 means a 256x256 window.

Yields:

tuple[int] – 4 element tuple containing the x size, y size, x offset and y offset of the window.
