riotiler 6.7.0

rio-tiler

User friendly Rasterio plugin to read raster datasets.

Documentation: https://cogeotiff.github.io/rio-tiler/
Source Code: https://github.com/cogeotiff/rio-tiler

Description
rio-tiler was initially designed to create slippy map
tiles from large raster data
sources and render these tiles dynamically on a web map. Since rio-tiler v2.0, we added many more helper methods to read
data and metadata from any raster source supported by Rasterio/GDAL.
This includes local and remote files via HTTP, AWS S3, Google Cloud Storage,
etc.
At the low level, rio-tiler is just a wrapper around the rasterio and GDAL libraries.
Features

Read any dataset supported by GDAL/Rasterio
from rio_tiler.io import Reader

with Reader("my.tif") as image:
print(image.dataset) # rasterio opened dataset
img = image.read() # similar to rasterio.open("my.tif").read() but returns a rio_tiler.models.ImageData object

User friendly tile, part, feature, point reading methods
from rio_tiler.io import Reader

with Reader("my.tif") as image:
img = image.tile(x, y, z) # read mercator tile z-x-y
img = image.part(bbox) # read the data intersecting a bounding box
img = image.feature(geojson_feature) # read the data intersecting a geojson feature
img = image.point(lon,lat) # get pixel values for a lon/lat coordinates

Enable property assignment (e.g nodata) on data reading
from rio_tiler.io import Reader

with Reader("my.tif") as image:
img = image.tile(x, y, z, nodata=-9999) # read mercator tile z-x-y

STAC support
from rio_tiler.io import STACReader

with STACReader("item.json") as stac:
print(stac.assets) # available asset
img = stac.tile( # read tile for asset1 and indexes 1,2,3
x,
y,
z,
assets="asset1",
indexes=(1, 2, 3), # same as asset_indexes={"asset1": (1, 2, 3)},
)

# Merging data from different assets
img = stac.tile( # create an image from assets 1,2,3 using their first band
x,
y,
z,
assets=("asset1", "asset2", "asset3",),
asset_indexes={"asset1": 1, "asset2": 1, "asset3": 1},
)

Xarray support (>=4.0)
import xarray
from rio_tiler.io import XarrayReader

ds = xarray.open_dataset(
"https://pangeo.blob.core.windows.net/pangeo-public/daymet-rio-tiler/na-wgs84.zarr/",
engine="zarr",
decode_coords="all",
consolidated=True,
)
da = ds["tmax"]
with XarrayReader(da) as dst:
print(dst.info())
img = dst.tile(1, 1, 2)

Note: The XarrayReader needs optional dependencies to be installed pip install rio-tiler["xarray"].

Non-Geo Image support (>=4.0)
from rio_tiler.io import ImageReader

with ImageReader("image.jpeg") as src:
im = src.tile(0, 0, src.maxzoom) # read top-left `tile`
im = src.part((0, 100, 100, 0)) # read top-left 100x100 pixels
pt = src.point(0, 0) # read pixel value

Note: ImageReader is also compatible with proper geo-referenced raster datasets.

Mosaic (merging or stacking)
from rio_tiler.io import Reader
from rio_tiler.mosaic import mosaic_reader

def reader(file, x, y, z, **kwargs):
with Reader(file) as image:
return image.tile(x, y, z, **kwargs)

img, assets = mosaic_reader(["image1.tif", "image2.tif"], reader, x, y, z)

Native support for multiple TileMatrixSet via morecantile
import morecantile
from rio_tiler.io import Reader

# Use EPSG:4326 (WGS84) grid
wgs84_grid = morecantile.tms.get("WorldCRS84Quad")
with Reader("my.tif", tms=wgs84_grid) as src:
img = src.tile(1, 1, 1)

Install
You can install rio-tiler using pip
$ pip install -U pip
$ pip install -U rio-tiler

or install from source:
$ git clone https://github.com/cogeotiff/rio-tiler.git
$ cd rio-tiler
$ pip install -U pip
$ pip install -e .

Plugins
rio-tiler-pds
rio-tiler v1 included several helpers for reading popular public datasets (e.g. Sentinel 2, Sentinel 1, Landsat 8, CBERS) from cloud providers. This functionality is now in a separate plugin, enabling easier access to more public datasets.
rio-tiler-mvt
Create Mapbox Vector Tiles from raster sources
Implementations
titiler: A lightweight Cloud Optimized GeoTIFF dynamic tile server.
cogeo-mosaic: Create mosaics of Cloud Optimized GeoTIFF based on the mosaicJSON specification.
