gbdxtools is a package for ordering imagery and launching workflows on DigitalGlobe's GBDX platform.
In order to use gbdxtools, you need GBDX credentials. Email [email protected] to get these.
Documentation is hosted here: http://gbdxtools.readthedocs.org/en/latest/. Example scripts can be found under the /examples directory of this repo.
Currently, the following Python versions are supported: 2.7, 3.3, 3.4, 3.5
See the license file for license rights and limitations (MIT).
There have been reports of authentication errors while creating a gbdx interface if the file ~/.gbdx-config is already populated with an access token. In this case, delete everything below and including the line [gbdx_token] within ~/.gbdx-config and create a new gbdx interface.
Conda is the recommended way to install gbdxtools:
conda install -c digitalglobe gbdxtools
These are various tips to follow if your installation fails.
Dependencies
As of gbdxtools version 0.11.3 libcurl and GDAL (>=2.1.0) are required. To install these packages use:
# Ubuntu users: sudo add-apt-repository -y ppa:ubuntugis/ubuntugis-unstable sudo apt update sudo apt-get install gdal-bin python-gdal python3-gdal libcurl4-openssl-dev # Mac Users: xcode-select --install # to install libcurl brew install https://raw.githubusercontent.com/OSGeo/homebrew-osgeo4mac/master/Formula/gdal-20.rb
Windows Users
Conda installation should work fine on windows for python version 2.7. If you are using python 3, you can install with pip, first install some dependencies with conda:
conda install -c conda-forge scipy conda install -c conda-forge scikit-image pip install gbdxtools
pip
Make sure you have the latest pip version:
pip install pip --upgrade
Ubuntu users
If you run into trouble with the installation of cryptography, make sure that the following dependencies are installed:
sudo apt-get install build-essential libssl-dev libffi-dev python-dev libcurl4-openssl-dev
Mac OSX Users
If you run into trouble with the installation of cryptography and see a message that <ffi.h> could not be found, you can run:
xcode-select --install
Then run "pip install gbdxtools" again. See stackoverflow for discussion on what is going wrong and why this fixes it (http://stackoverflow.com/questions/27328049/missing-usr-include-after-yosemite-and-xcode-install)
If you are running in a virtualenv and run into issues you may need upgrade pip in the virtualenv:
cd <your_project_folder> . venv/bin/activate pip install --upgrade pip pip install --upgrade gbdxtools # you might also need to remove token from your .gbdx-config file nano -w ~.gbdx-config # then, remove the [gbdx_token] section and json= part
GDAL
Versions of gbdxtools >= 0.11.3 require the GDAL library (>= 2.1.0) to be installed.
conda
If your installation with pip keeps failing, try creating a conda environment and installing gbdxtools within this environment.
For Ubuntu, install conda with the following commands (choose default options at prompt):
wget https://repo.continuum.io/miniconda/Miniconda2-latest-Linux-x86_64.sh bash Miniconda2-latest-Linux-x86_64.sh
For OS X, install conda with the following commands (choose default options at prompt):
wget https://repo.continuum.io/miniconda/Miniconda2-latest-MacOSX-x86_64.sh bash Miniconda2-latest-MacOSX-x86_64.sh
Make sure that conda is in your path. Then create a conda environment:
conda create -n env python ipython
Activate the environment:
source activate env
Upgrade pip (if required):
pip install pip --upgrade
Install gbdxtools:
conda install -c digitalglobe gbdxtools
Clone the repo:
git clone https://github.com/digitalglobe/gbdxtools.git cd gbdxtools
Start a virtual environment:
virtualenv venv . venv/bin/activate
Install the requirements:
pip install -r requirements.txt
Please follow this python style guide: https://google.github.io/styleguide/pyguide.html. 80-90 columns is fine.
Tests
This package uses pytest http://pytest.org/latest/contents.html.
pytest allows for tests to be written using various frameworks, so unittest.TestCase, pytest, and nose style tests will be detected and run.
To run all of the tests:
py.test tests
If you want only the unit or integration tests do either of:
py.test tests/integration py.test tests/unit
Note: you may have to issue the following in your virtualenv for the tests to find gbdxtools properly:
pip install -e .
Create a new version
To create a new version:
bumpversion ( major | minor | patch ) git push --tags
Don't forget to update the changelog and upload to pypi.
Contributing
Please contribute! Please make pull requests directly to master. Before making a pull request, please:
- Ensure that all new functionality is covered by unit tests.
- Verify that all unit tests are passing.
- Ensure that all functionality is properly documented.
- Ensure that all functions/classes have proper docstrings so sphinx can autogenerate documentation.
- Fix all versions in setup.py (and requirements.txt)
