Midgard is a collection of useful Python utilities used by the Geodetic institute at the Norwegian Mapping Authority (Kartverket). Although some of these are geodesy-specific, many are also useful in more general settings.

Note: Midgard is still in pre-alpha status. Its functionality will change, and it should not be depended on in any production-like setting.

Midgard is available at PyPI. You can install it by simply running

python -m pip install midgard

Midgard depends on several other brilliant Python packages, like for instance numpy, scipy, etc. We recommend using the Anaconda distribution to ease the installation of these dependencies.

Go to www.anaconda.com/download, and download Anaconda for Python 3.

If you have not already done so, download the Midgard source code from Github: github.com/kartverket/midgard. Then enter the main midgard directory before running the install command below.

cd midgard

You should now install the necessary dependencies using the environment.yml-file. You can do this either in your current conda environment, or choose to create a new midgard-environment. In order to use midgard in other projects you need to install midgard in the same environment as those projects.

To install midgard in your current environment, do

conda env update -f environment.yml

To install midgard in a new environment named midgard and activate it, do

conda env create -n midgard -f environment.yml
conda activate midgard

To do the actual installation of Midgard, use the flit packaging tool:

python -m flit install --dep production

If you want to develop the Midgard package, install it in editable mode using

python -m flit install -s

On Windows, you can install in editable mode using

python -m flit install --pth-file

Midgard comes organized into different subpackages. To see info about the different subpackages, use the Python help system:

>>> import midgard
>>> help(midgard)

Information about individual subpackages is also available on the Midgard website.
