A rio-tiler plugin to read from publicly-available datasets.
Important This is the new module for rio-tiler missions specific (ref: cogeotiff/rio-tiler#195)

Adding more dataset:
If you know of another publicly-available dataset that can easily be described with a "scene id", please feel free to open an issue.
On AWS, sentinel2, sentinel1, cbers and modis (in astraea-opendata) datasets are stored in requester
pays
buckets. This means that the cost of GET and LIST requests and egress fees for
downloading files outside the AWS region will be charged to the accessing
users, not the organization hosting the bucket. For rio-tiler and
rio-tiler-pds to work with such buckets, you'll need to set
AWS_REQUEST_PAYER="requester" in your shell environment.
When reading data, rio-tiler-pds performs partial reads when possible. Hence
performance will be best on data stored as Cloud Optimized GeoTIFF
(COG). It's important to note that Sentinel-2 scenes hosted
on AWS are not in Cloud Optimized format but in JPEG2000. Partial reads from
JPEG2000 files are inefficient, and GDAL (the library underlying rio-tiler-pds
and rasterio) will need to make many GET requests and transfer a lot of
data. This will be both slow and expensive, since AWS's JPEG2000 collection of
Sentinel 2 data is stored in a requester pays bucket.

Each dataset has its own submodule (e.g sentinel2: rio_tiler_pds.sentinel.aws)
from rio_tiler_pds.landsat.aws import LandsatC2Reader
from rio_tiler_pds.sentinel.aws import S1L1CReader
from rio_tiler_pds.sentinel.aws import (
S2JP2Reader, # JPEG2000
S2COGReader, # COG
)
from rio_tiler_pds.cbers.aws import CBERSReader
from rio_tiler_pds.modis.aws import MODISPDSReader, MODISASTRAEAReader
from rio_tiler_pds.copernicus.aws import Dem30Reader, Dem90ReaderAll Readers are subclass of rio_tiler.io.BaseReader and inherit its properties/methods.
- bounds: Scene bounding box
- crs: CRS of the bounding box
- geographic_bounds: bounding box in geographic projection (e.g WGS84)
- minzoom: WebMercator MinZoom (e.g 7 for Landsat 8)
- maxzoom: WebMercator MaxZoom (e.g 12 for Landsat 8)
- info: Returns band's simple info (e.g nodata, band_descriptions, ....)
- statistics: Returns band's statistics (percentile, histogram, ...)
- tile: Read web mercator map tile from bands
- part: Extract part of bands
- preview: Returns a low resolution preview from bands
- point: Returns band's pixel value for a given lon,lat
- feature: Extract part of bands
- bands (property): List of available bands for each dataset
All readers take scene id as main input. The scene id is used internaly by the reader to derive the full path of the data.
e.g: Landsat on AWS
Because the Landsat AWS PDS follows a regular schema to store the data (s3://{bucket}/c1/L8/{path}/{row}/{scene}/{scene}_{band}.TIF"), we can easily reconstruct the full band's path by parsing the scene id.
