Information provided documents historical events linked to the places specified.
API methods support queries against the same database accessed by search tools on the CHGIS website. Queries can specify placenames as romanized ASCII strings of UTF-8 encoded Chinese characters (either simplified or complex glyphs). Responses can be limited for particular date ranges, if desired.
CartoDB API: CartoDB is a geospatial database on the cloud. CartoDB allows users to make their data geolocal and map the data, as well as import geospatial datasets to create location-aware applications.
The CartoDB API allows developers to access and integrate the functionality of CartoDB with other applications and to create other applications. CartoDB offers a SQL API, as well as tile maps API. Example API methods include creating maps, performing queries of geospatial data, and rendering maps.
GeoGratis API: GeoGratis is an online platform that holds geospatial data, maps, documents, and other geographic resources from Canada.
