tea.xyz Spam Plagues npm and RubyGems Package Registries
Tea.xyz, a crypto project aimed at rewarding open source contributions, is once again facing backlash due to an influx of spam packages flooding public package registries.
Readme
This tool provides a tool to create continuous rasters of global publicly available tiles such as Pekel Occurence and ESA 10 m land cover. This is a simpler cousin of dem-stitcher
without the need for basic post-processing (e.g. fractional pixel translation and vertical datum transformations).
The API can be summarized as
from tile_mate import get_raster_from_tiles
bounds = [-120.55, 34.85, -120.25, 35.15]
X, p = get_raster_from_tiles(bounds, tile_shortname='esa_world_cover_2021')
# X is an c x m x n numpy array, where c is the number of channels specified by `count`
# p is a dictionary (or a rasterio profile) including relevant GIS metadata; CRS is epsg:4326
The rasters are returned in the global lat/lon projection epsg:4326
and the API assumes that bounds are supplied in this format.
import rasterio
with rasterio.open('esa_world_cover_2021_subset.tif', 'w', **p) as ds:
ds.write(X)
In order to easily manage dependencies, we recommend using dedicated project environments via Anaconda/Miniconda or Python virtual environments.
You can install the package with conda
/mamba
using:
mamba install tile_mate
or
pip install tile-mate
Alternatively, you can clone the repository and manage the environment using the environment.yml
file provided.
mamba env update -f environment.yml
conda activate tile-mate
pip
via pip install tile-mate
.For development, use pip
with -e
(editable) mode:
python -m pip install -e .
Python 3.10+ is supported.
We have notebooks to demonstrate common usage:

We welcome contributions to this open-source package. To do so:
We use flake8
and associated linting packages to ensure some basic code quality (see the environment.yml
). These will be checked for each commit in a PR. Try to write tests wherever possible.
This tool was developed to support OPERA.
