Using Python and OWSLib

OWSLib is a Python package which provides Pythonic access to OGC APIs and web services. Let’s see how easy it is to work with wis2box with standards-based tooling:

from owslib.ogcapi.features import Features

import pandas as pd

def pretty_print(input):
    print(json.dumps(input, indent=2))


api = 'http://localhost:8999/pygeoapi'

Let’s load the wis2box API into OWSLib and inspect some data

oafeat = Features(api)

collections = oafeat.collections()
print(f'This OGC API Features endpoint has {len(collections["collections"])} datasets')

for dataset in collections['collections']:
    print(dataset['title'])

malawi_obs = oafeat.collection_items('data.core.observations-surface-land.mw.FWCL.landFixed')
malawi_obs_df = pd.DataFrame(malawi_obs['features'])

# then filter by station
namitambo_obs = oafeat.collection_items('data.core.observations-surface-land.mw.FWCL.landFixed', wigos_station_identifier='0-454-2-AWSNAMITAMBO')
namitambo_obs_df = pd.DataFrame(namitambo_obs['features'])
print(malawi_obs_df.dtypes)
print(malawi_obs_df.head(3))
