{"title":"3D Buildings in Cologne (LoD2)","description":"<p>Together with a digital terrain model, 3D building models describe the natural terrain shape of the earth's surface, including all buildings and structures, in digital form and enable the representation of cities and towns in virtual worlds. Buildings can be modeled in different levels of detail (Level of Detail, LoD). In the 3D building model LoD2, the modeling of the buildings is done with standardized roof shapes such as a gable or hip roof.</p>\n<p>The data in this API is an extract from the statewide data (rectangle in the city of Cologne with 2 km x 3 km edge length, 10462 buildings).</p>\n<p>The building properties and their values are in German.</p>","links":[{"rel":"alternate","type":"text/html","title":"This document as HTML","href":"https://demo.ldproxy.net/cologne_lod2?f=html"},{"rel":"codelists","title":"Codelists used in the data","href":"https://demo.ldproxy.net/cologne_lod2/codelists"},{"rel":"conformance","title":"OGC API conformance classes implemented by this server","href":"https://demo.ldproxy.net/cologne_lod2/conformance"},{"rel":"data","title":"Access the data (Buildings)","href":"https://demo.ldproxy.net/cologne_lod2/collections"},{"rel":"http://www.opengis.net/def/rel/ogc/0.0/tileset-3dtiles","type":"text/html","title":"Access the data as 3D tiles (Buildings)","href":"https://demo.ldproxy.net/cologne_lod2/collections/building/3dtiles"},{"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/cologne_lod2/conformance"},{"rel":"http://www.opengis.net/def/rel/ogc/1.0/data","title":"Access the data (Buildings)","href":"https://demo.ldproxy.net/cologne_lod2/collections"},{"rel":"http://www.opengis.net/def/rel/ogc/1.0/styles","title":"Styles to render the data in maps","href":"https://demo.ldproxy.net/cologne_lod2/styles"},{"rel":"http://www.opengis.net/def/rel/ogc/1.0/tiling-schemes","title":"List of tile matrix sets implemented by this API","href":"https://demo.ldproxy.net/cologne_lod2/tileMatrixSets"},{"rel":"license","title":"Datenlizenz Deutschland - Zero – Version 2.0","href":"https://www.govdata.de/dl-de/zero-2-0"},{"rel":"self","type":"application/json","title":"This document","href":"https://demo.ldproxy.net/cologne_lod2?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/cologne_lod2/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/cologne_lod2/api?f=yaml"},{"rel":"service-doc","type":"text/html","title":"Documentation of the API","href":"https://demo.ldproxy.net/cologne_lod2/api?f=html"}],"attribution":"Geobasis NRW","extent":{"spatial":{"bbox":[[6.935375871536365,50.92910957124391,86.73813771420757,6.980223178327386,50.94852634901056,159.34124079030755]],"crs":"http://www.opengis.net/def/crs/OGC/0/CRS84h"},"temporal":{"interval":[["2025-11-27T10:00:11Z","2025-11-27T10:01:22Z"]],"trs":"http://www.opengis.net/def/uom/ISO-8601/0/Gregorian"}}}
