Functions

any_raster_to_xr_ds(function)	Allows a function to ingest AnyRasterType and convert it into a xr.DataArray:
aspect(xds, **kwargs)	Compute the aspect of a DEM.
collocate(reference, other[, resampling])	Collocate two georeferenced arrays: forces the other raster to be exactly georeferenced onto the reference raster by reprojection.
crop(xds, shapes[, nodata])	Cropping a dataset: setting nodata outside the given shapes AND cropping the raster to the shapes extent.
from_deg_to_meters(deg[, lat, decimals, ...])	Approximately convert a distance in degrees to a distance in meters.
from_meters_to_deg(meters[, lat, decimals, ...])	Approximately convert a distance in meters to a distance in degrees.
get_data_mask(xds)	Get nodata mask from a xarray.
get_dim_img_path(dim_path[, img_name])	Get the image path from a BEAM-DIMAP data.
get_extent(xds)	Get the extent of a raster as a geopandas.Geodataframe.
get_footprint(xds)	Get real footprint of the product (without nodata, in french == emprise utile)
get_nodata_mask(xds)
get_nodata_value(dtype)
get_nodata_value_from_dtype(dtype)	Get default nodata value from any given dtype.
get_nodata_value_from_xr(xds)	Retrieve the nodata from a xarray structure.
get_nodata_vector(ds[, default_nodata])	Get the nodata vector of a raster as a vector.
get_valid_vector(xds[, default_nodata])	Get the valid data of a raster, returned as a vector.
hillshade(xds[, azimuth, zenith])	Compute the hillshade of a DEM from an azimuth and zenith angle (in degrees).
mask(xds, shapes[, nodata])	Masking a dataset: setting nodata outside the given shapes, but without cropping the raster to the shapes extent.
merge_gtiff(crs_paths, crs_merged_path, **kwargs)	Merge rasters as a GeoTiff.
merge_vrt(crs_paths, crs_merged_path[, abs_path])	Merge rasters as a VRT.
paint(xds, shapes, value[, invert])	Painting a dataset: setting values inside the given shapes.
path_xarr_dst(function)
rasterize(xds, vector[, value_field, ...])	Rasterize a vector into raster format.
read(ds[, resolution, size, window, ...])	Read a raster dataset from a :
read_bit_array(bit_mask, bit_id)	Read bit arrays as a succession of binary masks (sort of read a slice of the bit mask, slice number bit_id)
read_uint8_array(bit_mask, bit_id)	Read 8 bit arrays as a succession of binary masks.
set_metadata(naked_xda, mtd_xda[, new_name])	Set metadata from a xr.DataArray to another (including rioxarray metadata such as encoded_nodata and crs).
set_nodata(xda, nodata_val)	Set nodata to a xarray that have no default nodata value.
sieve(xds, sieve_thresh[, connectivity])	Sieving, overloads rasterio function with raster shaped like an image: (1, h, w).
slope(xds[, in_pct, in_rad])	Compute the slope of a DEM (in degrees).
unpackbits(array, nof_bits)	Function found here
vectorize(xds[, values, keep_values, ...])	Vectorize a xarray to get the class vectors.
where(cond, if_true, if_false[, master_xda, ...])	Overloads xr.where with:
write(xds[, output_path, tags, ...])	Write raster to disk.
