3D Tiles is an OGC community standard for streaming and rendering massive 3D geospatial data. This talk shows workflows to convert 3D formats like CityGML to 3D Tiles and compares software tools like py3dtiles, mago 3DTiler and PLATEAU GIS Converter.

With QGIS Web Client (QWC) you can publish your maps on the Internet with the same rendering as QGIS Desktop thanks to QGIS Server. The environment consists of a modern responsive frontend written in JavaScript based on ReactJS and OpenLayers.

Most of today's web maps are using the [Web Mercator projection](https://en.wikipedia.org/wiki/WebMercatorprojection). A major issue of Web Mercator is the distortion of area sizes far from the equator.

Vector tiles are an efficient way to serve maps with a high volume of live data. IoT applications or maps with weather, traffic or other live data require a compact format for transmitting updated data.

[Shortbread](https://shortbread-tiles.org/) is an open schema for OSM vector tiles. It is intended to be a basic, lean, general-purpose vector tile schema for OpenStreetMap data.

[BBOX](https://github.com/sourcepole/bbox) is a new OGC API Open Source implementation, with support for established OGC services driven by MapServer or QGIS Server. BBOX is implemented in Rust, with a built-in high-performance web server.

Privacy aware Content Managment System (CMS) operators don't let their viewers accept cookies from an external map provider. But creating a map used to require specialized GIS knowledge and hosting a map server is not everyone's cup of tea.

"3D Tiles Next" is a major update of the "3D Tiles" OGC Community Standard 1.0. 3D Tiles are designed by Cesium GS, Inc. for streaming massive heterogeneous 3D geospatial datasets.

Workflow engines like Apache Airflow are commonly used in data engineering nowadays. They provide an infrastructure for setting up, executing and monitoring a defined sequence of tasks, arranged as a workflow application.
