pydov is a Python package to query and download data from [Databank Ondergrond Vlaanderen (DOV)](https://www.dov.vlaanderen.be). It is hosted on [GitHub](https://github.com/DOV-Vlaanderen/pydov) 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](https://www.dov.vlaanderen.be/portaal/?module=verkenner#ModulePage), 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](https://www.dov.vlaanderen.be/page/disclaimer) that applies to the other DOV services. Be sure to consult it when using DOV data with pydov.

## Installation

You can install `pydov` stable using pip:

```shell script
pip install pydov
```

Or clone the [git repository](https://github.com/DOV-Vlaanderen/pydov) 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](requirements_dev.txt) file. First, clone the [git repository](https://github.com/DOV-Vlaanderen/pydov).
We advice to use an Python development environment, for example with [conda](https://docs.conda.io/en/latest/miniconda.html) or
[virtualenv](https://virtualenv.pypa.io/en/latest/). Activate the (conda/virtualenv) environment and
install the package in development mode:

```shell script
pip install -e .[devs]
```

## Quick start

Read the [quick start](https://pydov.readthedocs.io/en/stable/quickstart.html) from the docs or jump straight in:

```python
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:
```
