pydov is a Python package to query and download data from Databank Ondergrond Vlaanderen (DOV). It is hosted on GitHub and development is coordinated by Databank Ondergrond Vlaanderen (DOV). DOV aggregates data about soil, subsoil and groundwater of Flanders and makes them publicly available. Interactive and human-readable extraction and querying of the data is provided by a web application, whereas the focus of this package is to support machine-based extraction and conversion of the data.
To get started, see the documentation at https://pydov.readthedocs.io.
Please note that downloading DOV data with pydov is governed by the same disclaimer that applies to the other DOV services. Be sure to consult it when using DOV data with pydov.
You can install pydov
stable using pip:
pip install pydov
Or clone the git repository and install with python setup.py install
to get the latest snapshot from the master branch.
To contribute to the code, make sure to install the package and all of the development dependencies enlisted in the requirements_dev.txt file. First, clone the git repository. We advice to use an Python development environment, for example with conda or virtualenv. Activate the (conda/virtualenv) environment and install the package in development mode:
pip install -e .[devs]

Read the quick start from the docs or jump straight in:
from pydov.search.boring import BoringSearch
from pydov.util.location import Within, Box
from owslib.fes2 import PropertyIsGreaterThan
boringsearch = BoringSearch()
dataframe = boringsearch.search(
query=PropertyIsGreaterThan(propertyname='diepte_tot_m', literal='550'),
location=Within(Box(107500, 202000, 108500, 203000))
)
The resulting dataframe contains the information on boreholes (boringen) within the provided bounding box (as defined by the location
argument)
with a depth larger than 550m:
