The query parameter limit=n controls the maximum number of features returned in a response document. there is also a server defined maximum which cannot be exceeded. the query parameter offset=n specifies the offset in the actual query result at which the response feature set starts. when used together, these two parameters allow paging through. In the system configuration directory, at etc pg featureserv.toml; relative to the directory from which the program is run, . config pg featureserv.toml; in a root volume at config pg featureserv.toml; to specify a configuration file directly use the config commandline parameter. in this case configuration files in other locations are ignored.

Retrieving data from web feature service (wfs) #. contents: introduce ogc wfs. use owslib to get capabilities of wfs api. retrieve data to geopandas. import geopandas as gpd import requests import geojson from pyproj import crs from owslib.wfs import webfeatureservice # specify the url for the backend. # here we are using data from statistics. The path functions {funid} items is the basic query to execute a function and return the set of features or data it produces. the response from a spatial function is a geojson feature collection contain ing the result. the response from a non spatial function is a json dataset containing the result.
