{"title":"CShapes Dataset of Historical Country Boundaries","description":"The CShapes 2.0 dataset maps the borders and capitals of independent states and dependent territories from 1886 to 2019. There are two versions of the dataset, which are based on the Gleditsch and Ward (1999) or the Correlates of War coding of independent states. Border changes were coded based on the Territorial Change Dataset by Tir et al (1998), the Encyclopedia of International Boundaries by Biger (1995) and the Encyclopedia of African Boundaries by Brownlie (1979).","links":[{"rel":"alternate","type":"text/html","title":"This document as HTML","href":"https://demo.ldproxy.net/cshapes?f=html"},{"rel":"conformance","title":"OGC API conformance classes implemented by this server","href":"https://demo.ldproxy.net/cshapes/conformance"},{"rel":"data","title":"Access the data (Historical Country Boundaries)","href":"https://demo.ldproxy.net/cshapes/collections"},{"rel":"http://www.opengis.net/def/rel/ogc/1.0/conformance","title":"OGC API conformance classes implemented by this server","href":"https://demo.ldproxy.net/cshapes/conformance"},{"rel":"http://www.opengis.net/def/rel/ogc/1.0/data","title":"Access the data (Historical Country Boundaries)","href":"https://demo.ldproxy.net/cshapes/collections"},{"rel":"http://www.opengis.net/def/rel/ogc/1.0/functions","title":"Additional CQL2 functions","href":"https://demo.ldproxy.net/cshapes/functions"},{"rel":"license","title":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","href":"https://creativecommons.org/licenses/by-nc-sa/4.0/"},{"rel":"search","title":"Stored queries for this API","href":"https://demo.ldproxy.net/cshapes/search"},{"rel":"self","type":"application/json","title":"This document","href":"https://demo.ldproxy.net/cshapes?f=json"},{"rel":"service-desc","type":"application/vnd.oai.openapi+json;version=3.0","title":"Definition of the API in OpenAPI 3.0","href":"https://demo.ldproxy.net/cshapes/api?f=json"},{"rel":"service-desc","type":"application/vnd.oai.openapi;version=3.0","title":"Definition of the API in OpenAPI 3.0","href":"https://demo.ldproxy.net/cshapes/api?f=yaml"},{"rel":"service-doc","type":"text/html","title":"Documentation of the API","href":"https://demo.ldproxy.net/cshapes/api?f=html"}],"extent":{"spatial":{"bbox":[[-180.0,-55.902227,180.0,83.113873]],"crs":"http://www.opengis.net/def/crs/OGC/1.3/CRS84"},"temporal":{"interval":[["1886-01-01T00:00:00Z","2019-12-31T00:00:00Z"]],"trs":"http://www.opengis.net/def/uom/ISO-8601/0/Gregorian"}},"attribution":"Schvitz, Guy, Seraina Rüegger, Luc Girardin, Lars-Erik Cederman, Nils Weidmann, and Kristian Skrede Gleditsch. 2022. <a href=\"https://icr.ethz.ch/publications/cshapes-2/\" target=\"_blank\">Mapping The International System, 1886-2017: The CShapes 2.0 Dataset</a>.
