A great feature of the hexagonal shape of H3 is how naturally it can delineate LineStrings such as roads, rivers in a connected and visually pleasing way. It would thus...
A common use-case is to generate all hexagons that intersect with a given polygon. That's not straightforward to do using H3. One approximate solution is to first generate a finer...
[h3-py](https://github.com/uber/h3-py) provides vectorized functions using Cython. They are still labelled experimental, but given their performance improvements, they should be utilized in H3-Pandas, if possible. ### Relevant links https://github.com/uber/h3-py/issues/141 https://github.com/uber/h3-py/pull/147 https://github.com/uber/h3-py/pull/166...
H3-Pandas has no implementation of [`h3_to_children`](https://h3geo.org/docs/api/hierarchy#h3tochildren). It should be straightforward to implement it using essentially the same logic as other collection-creating methods, such as [`k_ring`](https://github.com/DahnJ/H3-Pandas/blob/bf72ca97f1402b2a96d67c1cfd037f1cd1c28b8b/h3pandas/h3pandas.py#L213). Similarly to other methods, it...
[h3-py](https://github.com/uber/h3-py) has [multiple index APIs](https://github.com/uber/h3-py#apis). Currently, H3-Pandas is based on the `basic_str` API. For performance, it would make the most sense to work with the `numpy_int` or `memview_int` APIs. I...
Currently, `polyfill_resample` simple leaves any numeric values untouched. This makes sense for "relative" values, e.g. a percentage of unemployed, but makes less sense for absolute values, e.g. total population. For...

# What this PR does Addresses #2777 : Adds the option `metadata` to `DataFrame.to_file` that supports writing metadata in `dict[str, str]` format into GeoPackage files (fiona only). ### Details The...
Attempts to address https://github.com/zarr-developers/zarr-python/issues/1593 There are still two unsolved issues around the nonexistant `Store.from_path` in `core.py`. TODO: * [ ] Add unit tests and/or doctests in docstrings * [ ]...
