User friendly Rasterio plugin to read raster datasets.
Project description
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,pointreading methodsfrom 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:
ImageReaderis 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
