geostream 0.0.1

Python tool to interact with OGC APIs with ease.

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)
