Geostream
Geostream is a Python tool to interact with OGC APIs with ease and download geospatial data to Geopandas GeoDataFrames.
Status: Currently only works with WFS API and is very experimental by nature. Use at own risk.
Installation
geostream is available via PyPi and can be installed with:
pip install geostream
Basic usage
from geostream import WFS
# Endpoint for WFS API of the City of Helsinki
endpoint = "https://kartta.hel.fi/ws/geoserver/avoindata/wfs"
# Initialize WFS reader
# Note: API version can vary between data providers (by default 1.0.0 is used)
wfs = WFS(endpoint, version="2.0.0")
# See all available layers
wfs.get_layers()
# Store the id of the first layer
first_layer = wfs.get_layers()[0]
# Find info for specific layer
wfs.get_layer_info(first_layer)
# Download a GeoDataFrame with Helsinki as the extent
helsinki_gdf = wfs.get_gdf_from_place("Helsinki")
# Download the data into GeoDataFrame from the Helsinki Region
data = wfs.load_wfs(layer_id=first_layer, bounding_box=helsinki_gdf)
