cl-hubeau 0.4.0

Hubeau client to collect data from the different APIs

cl-hubeau

Simple hub'eau client for python

This package is currently under active development. Every API on Hub'eau will be covered by this package in due time.

At this stage, the following APIs are covered by cl-hubeau:

• piezometry/piézométrie
• hydrometry/hydrométrie
• drinking water quality/qualité de l'eau potable
• superficial waterbodies quality/qualité physico-chimique des cours d'eau'

For any help on available kwargs for each endpoint, please refer directly to the documentation on hubeau (this will not be covered by the current documentation).

Assume that each function from cl-hubeau will be consistent with it's hub'eau counterpart, with the exception of the size and page or cursor arguments (those will be set automatically by cl-hubeau to crawl allong the results).

Configuration

First of all, you will need API keys from INSEE to use some high level operations, which may loop over cities'official codes. Please refer to pynsee's API subscription Tutorial for help.

Basic examples

Clean cache

from cl_hubeau.utils import clean_all_cache
clean_all_cache

Piezometry

3 high level functions are available (and one class for low level operations).

Get all piezometers (uses a 30 days caching):

from cl_hubeau import piezometry
gdf = piezometry.get_all_stations()

Get chronicles for the first 100 piezometers (uses a 30 days caching):

df = piezometry.get_chronicles(gdf["code_bss"].head(100).tolist())

Get realtime data for the first 100 piezometers:

A small cache is stored to allow for realtime consumption (cache expires after only 15 minutes). Please, adopt a responsible usage with this functionnality !

df = get_realtime_chronicles(gdf["code_bss"].head(100).tolist())

Low level class to perform the same tasks:

Note that :

• the API is forbidding results > 20k rows and you may need inner loops
• the cache handling will be your responsibility, noticely for realtime data

with piezometry.PiezometrySession() as session:
    df = session.get_chronicles(code_bss="07548X0009/F")
    df = session.get_stations(code_departement=['02', '59', '60', '62', '80'], format="geojson")
    df = session.get_chronicles_real_time(code_bss="07548X0009/F")

Hydrometry

4 high level functions are available (and one class for low level operations).

Get all stations (uses a 30 days caching):

from cl_hubeau import hydrometry 
gdf = hydrometry.get_all_stations()

Get all sites (uses a 30 days caching):

gdf = hydrometry.get_all_sites()

Get observations for the first 5 sites (uses a 30 days caching): Note that this will also work with stations (instead of sites).

df = hydrometry.get_observations(gdf["code_site"].head(5).tolist())

Get realtime data for the first 5 sites (no cache stored):

A small cache is stored to allow for realtime consumption (cache expires after only 15 minutes). Please, adopt a responsible usage with this functionnality !

df = hydrometry.get_realtime_observations(gdf["code_site"].head(5).tolist())

Low level class to perform the same tasks:

Note that :

• the API is forbidding results > 20k rows and you may need inner loops
• the cache handling will be your responsibility, noticely for realtime data

with hydrometry.HydrometrySession() as session:
    df = session.get_stations(code_station="K437311001")
    df = session.get_sites(code_departement=['02', '59', '60', '62', '80'], format="geojson")
    df = session.get_realtime_observations(code_entite="K437311001")
    df = session.get_observations(code_entite="K437311001")

Drinking water quality

2 high level functions are available (and one class for low level operations).

Get all water networks (UDI) (uses a 30 days caching):

from cl_hubeau import drinking_water_quality 
df = drinking_water_quality.get_all_water_networks()

Get the sanitary controls's results for nitrates on all networks of Paris, Lyon & Marseille (uses a 30 days caching) for nitrates

networks = drinking_water_quality.get_all_water_networks()
networks = networks[
    networks.nom_commune.isin(["PARIS", "MARSEILLE", "LYON"])
    ]["code_reseau"].unique().tolist()

df = drinking_water_quality.get_control_results(
    codes_reseaux=networks,
    code_parametre="1340"
)

Note that this query is heavy, even if this was already restricted to nitrates. In theory, you could also query the API without specifying the substance you're tracking, but you may hit the 20k threshold and trigger an exception.

You can also call the same function, using official city codes directly:

df = drinking_water_quality.get_control_results(
    codes_communes=['59350'],
    code_parametre="1340"
)

Low level class to perform the same tasks:

Note that :

• the API is forbidding results > 20k rows and you may need inner loops
• the cache handling will be your responsibility

with drinking_water_quality.DrinkingWaterQualitySession() as session:
    df = session.get_cities_networks(nom_commune="LILLE")
    df = session.get_control_results(code_departement='02', code_parametre="1340")

Superficial waterbodies quality

4 high level functions are available (and one class for low level operations).

Get all stations (uses a 30 days caching):

from cl_hubeau import superficial_waterbodies_quality 
df = superficial_waterbodies_quality.get_all_stations()

Get all operations (uses a 30 days caching):

from cl_hubeau import superficial_waterbodies_quality
df = superficial_waterbodies_quality.get_all_operations()

Note that this query is heavy, users should restrict it to a given territory. For instance, you could use :

df = superficial_waterbodies_quality.get_all_operations(code_region="11")

Get all environmental conditions:

from cl_hubeau import superficial_waterbodies_quality
df = superficial_waterbodies_quality.get_all_environmental_conditions()

Note that this query is heavy, users should restrict it to a given territory. For instance, you could use :

df = superficial_waterbodies_quality.get_all_environmental_conditions(code_region="11")

Get all physicochemical analysis:

from cl_hubeau import superficial_waterbodies_quality
df = superficial_waterbodies_quality.get_all_analysis()

Note that this query is heavy, users should restrict it to a given territory and given parameters. For instance, you could use :

df = superficial_waterbodies_quality.get_all_analysis(
    code_departement="59", 
    code_parametre="1313"
    )

Low level class to perform the same tasks:

Note that :

• the API is forbidding results > 20k rows and you may need inner loops
• the cache handling will be your responsibility

with superficial_waterbodies_quality.SuperficialWaterbodiesQualitySession() as session:
    df = session.get_stations(code_commune="59183")
    df = session.get_operations(code_commune="59183")
    df = session.get_environmental_conditions(code_commune="59183")
    df = session.get_analysis(code_commune='59183', code_parametre="1340")
