Additionally, existing thematic data **embedded** within the visualization datasets is also supported.\n\nSee [release announcements](RELEASES.md) and [change logs](CHANGES.md) for the complete list of changes made in this version, as well as in previous ones.\n\nIntroduction\n-------\nThe **3DCityDB-Web-Map-Client** is a web-based front-end for high-performance 3D visualization and interactive exploration of **arbitrarily large semantic 3D city models** and other geospatial data. The web client utilizes the [Cesium Virtual Globe](https://cesium.com/) as its 3D geo-visualization engine based on HTML5 and Web Graphics Library (WebGL) to provide hardware acceleration and cross-platform functionalities like displaying 3D graphic contents on web browsers without the needs of additional plugins.\n\nThe key features and functionalities of the 3DCityDB-Web-Map-Client is summarized as follows: \n\n* Support for efficient displaying, caching, prefetching, dynamic loading and unloading of large pre-styled 3D visualization models in the form of **tiled KML/glTF datasets exported from the 3DCityDB** using the Importer/Exporter\n* Intuitive user interface for adding and removing **arbitrary number of data layers** for 3D visualization (KML/glTF, GeoJSON, Cesium 3D Tiles, I3S), together with WMS/WMTS imagery layer, and Cesium digital terrain model\n* Support for linking the 3D visualization models (KML/glTF, GeoJSON, Cesium 3D Tiles, I3S) with **external thematic data sources**, such as **Google Spreadsheets** and **PostgreSQL/PostgREST**, allowing for querying the thematic data of every 3D object\n* Support for displaying the existing **thematic data embedded** within the visualization datasets, such as KML, GeoJSON, Cesium 3D Tiles and I3S\n* Support for rich interaction with 3D visualization models, for example, **highlighting** of 3D objects on mouseover and mouseclick as well as **hiding** and **showing** of multiple selected 3D objects\n* Support for exploring a 3D object of interest from **different view perspectives** using third-party mapping services like **Microsoft Bing Maps** with oblique view, **Google Streetview**, and a combined version (**DualMaps**) \n* Support for on-the-fly activating and deactivating **shadow visualization** of 3D objects and Cesium digital terrain models\n* Support for collaborative creation and sharing of the workspace of the 3DCityDB-Web-Map-Client by means of **generating a scene link** including information about the current camera perspective, activation status of the shadow visualization, parameters of the current loaded data layers, etc. This link can be easily shared or bookmarked, and can be reopened in a browser on different machines\n* Support for **mobile devices** (smartphones, tablets, etc.) with live tracking of geolocation and orientation\n* Packaged as a [**Docker image**](https://hub.docker.com/r/tumgis/3dcitydb-web-map/tags?page=1\u0026ordering=last_updated) for fast and convenient deployment\n\nArchitecture\n-------\n\u003cp align=\"center\"\u003e\n\u003cimg src=\"theme/img/3dcitydb-web-map-client-architecture.jpg\" width=\"800\" /\u003e\n\u003c/p\u003e\n\nLicense\n-------\nThe 3DCityDb-Web-Map-Client is licensed under the [Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0).

Therefore, make sure the client is called from an HTTPS page or your own localhost. \n\nAdditional important notes:\n\n* Test the client on devices equipped with GPS.\n* If the Geolocation API asks for permission to retrieve your current location, select \"Allow\".\n\nMore information\n----------------\n\nThe 3DCityDB-Web-Map-Client is a part of the [3DCityDB Software Suite](https://www.3dcitydb.org) for managing and working with large semantic 3D city models in CityGML. However, the web client can also be used as a separate stand-alone component.\n\n[OGC CityGML](https://www.opengeospatial.org/standards/citygml) is an open data model and XML-based format for the storage and exchange of semantic 3D city models. It is an application schema for the [Geography Markup Language version 3 (GML3)](https://www.opengeospatial.org/standards/gml), the extendible international standard for spatial data exchange issued by the Open Geospatial Consortium (OGC) and the ISO TC211. The aim of the development of CityGML is to reach a common definition of the basic entities, attributes, and relations of a 3D city model. CityGML is an international OGC standard and can be used free of charge.\n\n## Acknowledgement\n\nThe development of these methods and implementations were supported \nand partially funded by the company [CADFEM](https://www.cadfem.net) \nwithin a dedicated collaboration project in the context of the \n[Leonhard Obermeyer Center (LOC)](https://www.ed.tum.de/loc) \nat the [Technical University of Munich (TUM)](https://www.tum.de).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F3dcitydb%2F3dcitydb-web-map","html_url":"https://awesome.ecosyste.ms/projects/github.com%2F3dcitydb%2F3dcitydb-web-map","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2F3dcitydb%2F3dcitydb-web-map/lists"}
