About the OpenDEM Project

This is an open project for sharing the 3rd dimension of the earths surface.

There are many ways to record the earth´s surface:

- Aerial photography
- Remote sensing
- Barometers
- Microdrones
- Trachymeter

If you have any height data that could be licensed under the Open Database License, please provide the dataset, so it can be used by the public.

Do not provide any data that is protected by copyright laws!

There are many other ways to support the project, so please visit the Roadmap section.

Help is wanted!

Why Open Data is important

The extension and dissemination of human knowledge is one of the most important factors for a sustainable society. In most decisions that affect society, spatial aspects are an important factor. Therefore it is obvious that geoinformation must be freely accessible, without restrictions, for the user to arrive at sustainable and fractually based decisions.

The collective collection of data and knowledge outside the classical hierarchical structures via the internet is a relatively new phenomenon, often called “Commons based Peer Production” or just “Peer Production”. It is more than "just" software or data. If you want to know more about this kind of production and how it could change our society, the Wikipedia article "Commons-based peer production" is a good starting point.
