Publishing raster data to OGC API - Coverages

OGC API - Coverages provides geospatial data access functionality to raster data.

To add raster data to pygeoapi, you can use the dataset example in Configuration as a baseline and modify accordingly.

Providers

pygeoapi core feature providers are listed below, along with a matrix of supported query parameters.

Provider

range-subset

subset

bbox

datetime

rasterio

xarray

Below are specific connection examples based on supported providers.

Connection examples

rasterio

The rasterio provider plugin reads and extracts any data that rasterio is capable of handling.

providers:
    - type: coverage
      name: rasterio
      data: tests/data/CMC_glb_TMP_TGL_2_latlon.15x.15_2020081000_P000.grib2
      options:  # optional creation options
          DATA_ENCODING: COMPLEX_PACKING
      format:
          name: GRIB
          mimetype: application/x-grib2

Note

The rasterio provider format.name directive requires a valid GDAL raster driver short name.

xarray

The xarray provider plugin reads and extracts NetCDF and Zarr data.

providers:
    - type: coverage
      name: xarray
      data: tests/data/coads_sst.nc
      # optionally specify x/y/time fields, else provider will attempt
      # to derive automagically
      x_field: lat
      x_field: lon
      time_field: time
      format:
         name: netcdf
         mimetype: application/x-netcdf

providers:
    - type: coverage
      name: xarray
      data: tests/data/analysed_sst.zarr
      format:
         name: zarr
         mimetype: application/zip

Note

Zarr files are directories with files and subdirectories. Therefore a zip file is returned upon request for said format.
