## Welcome

Welcome to gdptools, a python package for grid- or polyon-to-polygon area-weighted interpolation statistics.

![Welcome figure](./docs/assets/Welcom_fig.png)

<figcaption>Example grid-to-polygon interpolation.  A) Huc12 basins for Delaware River Watershed. B) Gridded monthly water evaporation amount (mm) from TerraClimate dataset. C) Area-weighted-average interpolation of gridded TerraClimate data to Huc12 polygons.</figcaption>

## Documentation

[gdptools documentation](https://gdptools.readthedocs.io/en/latest/)

## Features

- Grid-to-polygon interpolation of area-weighted statistics.
- Use [Mike Johnson's OPeNDAP catalog][1] to access over 1700 unique datasets.
- Use any gridded dataset that can be read by xarray.
- Uses spatial index methods for improving the efficiency of areal-wieght calculation detailed by [Geoff Boeing][2]

## Data Requirements

### Data - xarray (gridded data) and Geopandas (Polygon data)

- [Xarray](https://docs.xarray.dev/en/stable/)

  - Any endpoint that can be read by xarray and contains projected coordinates.
    - The endpoint can be supplied by the OPeNDAP catalog or from a user-supplied end-point.
  - Projection: any projection that can be read by proj.CRS (similar to Geopandas)

- [Geopandas](https://geopandas.org/en/stable/)
  - Any file that can be read by Geopandas
  - Projection: any projection that can be read by proj.CRS
