## Introduction

This is a python module that helps change scales of spatial data sets.

It relies on the [H3](https://h3geo.org) hexagonal grid’s hierarchical

indexing functionalities and aims to add to that the data

transformations that need to be done when navigating between levels of

the hierarchy.

A presentation on the topic can be found

here

### THIS MODULE IS UNDER DEVELOPMENT

The package website introduces the use cases and the different functionalities that are covered so far.

## Main functionalities

### Rastapar

The command line tool allows for efficient, multi core ingestion of rasters into parquet tables. 

### Scalenav modules

A set of modules provides python functions for performing a operations with data sets expressed as H3 cells. Additionaly, a module with the equivalent high performance functions written with ibis and duckdb.
