sertit.rasters_rio.get_valid_vector¶
- get_valid_vector(dst: Union[str, tuple, rasterio.io.DatasetReader], default_nodata: int = 0) geopandas.geodataframe.GeoDataFrame [source]¶
Get the valid data of a raster as a vector.
Pay attention that every nodata pixel will appear too. If you want only the footprint of the raster, please use get_footprint.
>>> raster_path = "path\to\raster.tif" # Classified raster, with no data set to 255 >>> nodata1 = get_nodata_vec(raster_path) >>> # or >>> with rasterio.open(raster_path) as dst: >>> nodata2 = get_nodata_vec(dst) >>> nodata1 == nodata2 True
- Parameters
dst (PATH_ARR_DS) – Path to the raster, its dataset, its xarray or a tuple containing its array and metadata
default_nodata (int) – Default values for nodata in case of non existing in file
- Returns
Nodata Vector
- Return type
