Fortgeschrittene Web-Map Techniken rund um OpenLayers (fossgis2026)

from Chaos Computer Club - recent audio-only feed · host Andreas Hocevar

Dieser Beitrag zeigt, wie man mit OpenLayers, proj4js, geotiff.js und PMTiles Kartenapplikationen erstellen kann, die über die bekannte "Basiskarte mit thematischen Punktsymbolen drauf" hinausgehen. Die Verarbeitung von Geodaten kennt inzwischen auch im Web-Browser kaum mehr Grenzen. Es gibt leistungsstarke Web Map Libraries wie OpenLayers, Pendants zu essenziellen C-Bibliotheken wie Proj4js, die Unterstützung gängiger Formate wie (Geo)Tiff, oder Tools zur Erstellung und Nutzung effizienter, cloud-basierter Speicher- und Transferformate wie PMTiles. All das eröffnet Möglichkeiten, die denen von Desktop- und Server-Software kaum nachstehen. Dieser Beitrag zeigt anhand konkreter Beispiele, angereichert mit Einblicken in Programmcode, wie sich die genannten Technologien kombinieren lassen, um Geodaten aus verschiedenen Quellen direkt im Browser zu hochwertigen räumliche Information zu verarbeiten. Somit lassen sich ohne Installation von Software auf benutzerfreundliche Weise Inhalte transportieren, die noch vor wenigen Jahren Desktop-GIS Systemen und Fachpersonal vorbehalten waren.
