# Webassembly: Wo wir sind und wo es hingehen könnte (DE)

Lightning Talk @ **[FOSSGIS 2021](https://www.fossgis-konferenz.de/2021/)** (English: "**_Webassembly: Where we are and where we are heading_**").

> **Video**: https://media.ccc.de/v/fossgis2021-9601-webassembly-wo-wir-sind-und-wo-es-hingehen-knnte

> **Slides**: https://boardend.github.io/fossgis-2021-webassembly/

> **Session**: https://www.fossgis-konferenz.de/2021/sessions/ZVFZQQ.php

## Description (DE)

Webassemblys Potential ist insbesondere für die Verarbeitung und Visualisierung von Geo-Daten noch nicht ausgeschöpft. In diesem Talk möchte ich Ihnen die aktuelle Adaption in FOSSGIS-Projekten, die technische Weiterentwicklung sowie mögliche Zukunftsszenarien von Webassembly aufzeigen.

## Scritps

- [`./scripts/gdal.html`](https://boardend.github.io/fossgis-2021-webassembly/scripts/gdal.html)

  - in-browser GDAL example, uses [gdal3.js](https://github.com/trylab-net/gdal3.js)

- [`./scripts/frames2mp4.html`](https://boardend.github.io/fossgis-2021-webassembly/scripts/frames2mp4.html)

  - stiches, fades and renders frames from [Google Earth Studio](https://www.google.com/intl/de/earth/studio/) with [ffmpeg.wasm](https://github.com/ffmpegwasm/ffmpeg.wasm) to a .mp4 video
