Toolbox for 3D geonumerical calculations
NEW: Supports both Python 2.7 and 3.6 from now.
geonum provides functionality for geographical calculations in three dimensions and includes interfaces for accessing and processing of topographic data. Most of the features (e.g. distance retrievals) are based on the two fundamental objects GeoPoint and GeoVector3D which are inherited from the respective 2D base classes of the LatLon23 module and were expanded including the 3rd dimension (altitude). Geonum features online access to topographic data from the SRTM dataset, using the SRTM module. Furthermore, topographic data from the ETOPO1 Dataset is supported.
News / Notifications
- Now also available and tested in Python 3.6
- Changed requirement LatLon -> LatLon23 to support Python 3
- Refactoring of basemap dependency to cartopy
- TopoData should be based on xarray.DataArray
- Support for more topographic datasets, interpolation of gaps in topodata

It is recommended to use Anaconda as Python package manager as it includes many of the required dependencies and makes life easier when it comes to the installation or upgrade of non-straight forward installations of additional requirements such as OpenCV or basemap.
Optional dependencies (to use extra features)
Geonum can be installed from PyPi using:
pip install geonum
or from source by downloading and extracting the latest release. After navigating to the source folder (where the setup.py file is located) call:
python setup.py install
If the installation fails make sure, that all dependencies (see above) are installed correctly. geonum is tested for Python 2.7.
Instructions and code documentation
The code documentation of geonum is hosted on Read The Docs
After installation try running the example scripts in order to test the installation. The scripts are also meant to provide an easy start into the main features of geonum.
Supported ETOPO1 files
In order to use topography data from the ETOPO1 dataset, please download and unzip one of the following files to the package folder geonum/local_topo_data/. Tested and supported are the following two files (grid registered):
The local installation folder can be accessed via:
import geonum print geonum.LOCAL_TOPO_PATH
If a valid data file is stored in this folder, it will be detected automatically. It is also possible to store the topodata at another location (e.g. <data_path>). In this case, the local path to the folder containing the topograph files needs to be provided, e.g.:
import geonum access = geonum.topodata.TopoDataAccess(mode = "etopo1", local_path = <data_path>)
If the path is valid, it will be added to the installation file LOCAL_TOPO_PATHS.txt
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
