# BPNSdata
bpnsdata is a package to add environmental data to a geopandas DataFrame. There is no support for multiindex columns,
so one level has to be selected or dropped out before using it.
Right now only Belgian Part of the North Sea data is available for all the classes. However, some classes are not
restricted to the bpns and can be used to add environmental data to other parts of the world.
## Install
Use the package manager [pip](https://pip.pypa.io/en/stable/) to install
the dependencies.
```bash
pip install -r requirements.txt
```
If you are working on Windows, it can be tricky to install geopandas.
We recommend to install FIRST the following packages (in this order) by downloading the wheels of:
* GDAL
* rasterio
* Fiona
You can follow this tutorial if you're not familiar with wheels and/or pip:
https://geoffboeing.com/2014/09/using-geopandas-windows/
Build the project
```bash
python setup.py install
```
## Environmental data
Environmental data can be added by specifying it in the env_vars variable when calling the main class SeaDataManager.
To do so, it is necessary to have gps information, which can be stored in a .gpx file, in the "waypoints" or
"track_points" layer. It can also be loaded as a csv or a shp file.
Then the algorithm finds the point which is closest in time for row of the dataframe.
The available data sources are:
* csv: Static geo data in a csv file. Files to be provided by the user
* time: Information about the moment of the day and the moon
* moon cycle
* day moment
* emodnet: wcs data from EMODnet
* shipping density
* bathymetry
* raster: raster data (tiff images)
* seabed habitats
* habitat suitability
* griddap: RBINS data from the erddap server
* sea surface
* wave information
* wrakken_bank: shipwreck information
* meetnet_vlaamse_banken: read weather data from the buoys of the meetnet vlaamse banken
For easier running of the classes, there is a main class called SeaDataManager, which allows to run all the
desired environmental variables in one line of code.
### EMODnet
Entry point to download map data from EMODnet using WCS. Coverage to be checked in EMODnet, but larger than BPNS.
The implemented classes so far are:
##### Shipping
Shipping activity from https://www.emodnet-humanactivities.eu/
Adds the route density or the shipping intensity from the month of the deployment to the dataset, considering the
location, the year and the month.
It adds the columns:
* route_density
* ship_density
(depending on the layer type selected)
##### Bathymetry
Adds the mean bathymetry (https://www.emodnet-bathymetry.eu/) layer considering location (no time considered)
The output column is:
* bathymetry
### Raster Data
Raster Data represents geographical data. Only BPNS available
The two outputs are:
##### Seabed habitats
Adds the sea habitat (https://www.emodnet-seabedhabitats.eu/).
The output columns are:
* seabed_habitat
* substrate
##### Benthic habitats
Habitat suitability map from the publication ([1]V. Van Lancker, G. Moerkerke, I. Du Four, E. Verfaillie, M. Rabaut,
and S. Degraer, “Fine-scale Geomorphological Mapping of Sandbank Environments for the Prediction of Macrobenthic
Occurences, Belgian Part of the North Sea,” Seafloor Geomorphology as Benthic Habitat,
pp. 251–260, 2012, doi: 10.1016/B978-0-12-385140-6.00014-1.).
The closest point from the maps is added to the each point of the dataset. The output column is:
* benthic_habitat
### ERDDAP RBINS Data
Sea State Data from RBINS (https://erddap.naturalsciences.be/erddap/index.html).
Coverage to be checked in the RBINS erddap website, but restricted to North Sea.
In this version only the tables BCZ_HydroState_V1 and WAM_ECMWF are implemented.
##### Sea Surface
The data is added from the table: BCZ_HydroState_V1.
* surface_baroclinic_eastward_sea_water_velocity
* surface_baroclinic_northward_sea_water_velocity
* sea_surface_height_above_sea_level
* sea_surface_salinity
* sea_surface_temperature
* surface_baroclinic_sea_water_velocity
##### Wave Data
The data is added from the table: WAM_ECMWF
Output columns:
* hs: wave height in cm
* tm_1: wave period
### Time Data
Data Related to time series. It adds the time of the day (day, night, twilight dawn...) and the moon phase.
The calculation is done using skyfield (https://rhodesmill.org/skyfield/).
Coverage in all the world.
The output columns are:
* moment_day (twilight, dawn, day, night)
* moon_phase (in radians)
### Csv Data
Static data that is stored in a csv, with a lat and a lon columns (names to be given).
It returns the closest point of all the csv, the distance to it, the coordinates and also other columns selected by the
user with the specified suffix.
### Wrakken Bank
Will add information about the closest shipwreck. The data is extracted from https://wrakkendatabank.afdelingkust.be/.
Following information will be added:
* shipwreck_distance: Distance to closest shipwreck
* shipwreck_lat
* shipwreck_lon
* shipwreck_name
### Meetnet Vlaamse Banken
Read the available speed at the closest buoy from https://api.meetnetvlaamsebanken.be/V2-help/.
Attention! To be able to use this feature you need to have a user registered at Meet Net Vlaamse Banken. You can do
it for free from their webpage. Then you need the username and the password. You can pass it directly to the created
objects, but if you want to use them in the SeaDataManager you will have to add the username and the password as
environmental variables (username_bank and password_bank).
So far, rainfall (NSI) and average wind speed at 10 m (WVC) are implemented.
It adds to the DataFrame a column with the value of the data, the id of the specified buoy and the distance to the buoy.
The id of the buoy is represented by the sum of the location id + the data id. i.e., in the buoy OMP, the id for
precipitation is OMP+NSI=OMPNSI
## Usage
Possible ways of loading the data
```python
import bpnsdata
import pandas as pd
import numpy as np
# When the desired df is already on a gpx or a csv with coordinates (in this case, imagine the gpx itself
# contains the rows to analyze
geofile = 'data/VG.gpx'
geodf = bpnsdata.SurveyLocation(geofile).geotrackpoints
# Could also be done directly using geopandas:
geodf = geopandas.read_file(geofile)
gedf = geodf.set_index(pd.to_datetime(geodf['time']))
# Could be that we have a df (here a random one) and we want to add a geolocation to it
# Create a random dataframe to work with
time_index = pd.date_range(start='2020-10-12 11:35', end='2020-10-12 12:00', freq='m', tz='UTC')
random_data = np.random.randint(5, 30, size=10)
df = pd.DataFrame(random_data, index=time_index)
```
Use of the SeaDataManager
```python
import bpnsdata
# Define the seadatamanager
env_vars = ['shipping', 'time', 'wrakken_bank', 'habitat_suitability', 'bathymetry'
'seabed_habitat', 'sea_surface', 'sea_wave', 'rain', 'wind']
manager = bpnsdata.SeaDataManager(env_vars)
# If the data is without geometry, then:
geodf = manager.add_geodata(df, gpx_file)
# Once the data has geometry:
df_env = manager(geodf)
```
Use without the SeaDataManager**
```python
import bpnsdata
# For example, for shipping:
shipping = bpnsdata.ShippingData(layer_name='rd', boat_type='All')
df_env = shipping(geodf)
```
