Documentation Status

Make GIFs from time-stacked xarray.DataArrays (time, [optional band], y, x), dead-simple.

from geogif import gif, dgif
gif(data_array)
dgif(dask_data_array).compute()

Animation of shoreline moving on the coast of Cape Cod

The "geo" part is a lie, actually. The arrays don't have to be geospatial in nature. But I called it GeoGIF because:

  1. Wanting to animate a time-stack of imagery (like you'd get from stackstac) is a common task in the earth-observation/geospatial world.
  2. I think GeoGIF is a hilarious idea1.

1: To ruin the joke, it sounds like GeoTIFF, a ubiquitous geospatial image format. If you also think this is a funny idea, and believe you'd have a better use for the name than I do, I'd happily cede it to you.

Installation

pip install geogif

Documentation

See https://geogif.readthedocs.io/en/latest/.

Development

GeoGIF is managed by Poetry, so be sure that's installed first. To develop locally, first fork or clone the repo. Then, to set up a virtual environment and install the necessary dependencies:

cd geogif
poetry install -E tests -E docs

Running Tests

GeoGIF has some basic end-to-end tests, written with Hypothesis. To run:

pytest

This will take ~30 seconds (longer the first time), as Hypothesis generates fake data to root out possible errors.

Code style

GeoGIF is formatted with shed, in order to allow for as few opinions as possible.

    please remove python version limit

    hi,

    looks like great tool! I tried to install it using pip, but got error: ERROR: Package 'geogif-0.1.2' requires a different Python: 3.7.6 not in '>=3.8,<4.0'

    could you please remove the strict dependency on python 3.7.6 ?

    thank you

    Loosen version restrictions

    Necessary for https://github.com/gjoseph92/stackstac/issues/51. We have to do a crazy dance because of https://github.com/python-poetry/poetry/issues/697.

    This lockfile is out of date. I've manually overridden pyproject.toml to an unsolveable state in order to bump the xarray version and cut a release. This will be resolved in a future commit.

    CLI Execution

    This is super slick! I love how quick and easy it is. Any interest in an install-able little executable we could just run from the CLI?

    Something like that?
