Analysis of free web mapping libraries

Further development of front-end technologies makes client-side web mapping
applications a promising way of providing (interactive explorable) geodata to the global
community. Which libraries address this topic and how the implementation of essential
web GIS functionalities can be done using LeafLet, MapLibre or OpenLayers are questions
analysed in this document. Therefore, internet research has been done collecting already
existing solutions making use of the respective functionalities of the libraries. As a result,
links to implementation examples, plugins or references in the API documentations have
been gathered in a functionality matrix.
The information gained by this research is used for developing and implementing an
interactive web mapping application as part of the World Heat Flow Database Project.
Beside this, the document offers an overview for people who are new to this topic,
provides code examples for common web GIS features and makes the readers familiar
with topic-specific vocabulary and terms.
