Research Project

3D-MAPP: 3D-MicroMapping of Big 3D Geo-Datasets in the Web

Objective

The research project 3D-MAPP develops a web-based methodology to obtain digital geodata via the combination of data analysis by human and machine. Through a quick and easy-to-use 3D Web visualization users are able – in a few seconds – to solve 3D micro mapping tasks, which can hardly or even not be solved by automatic algorithms. Based on an extensive user study the idea of 3D-MAPP shall be evaluated empirically.

News

Within the project we implemented two crowdsourcing tasks. Both applications can be tested here:

• Citizen science project 3D vegetation

Further project-related news can be found in our GIScience News Blog.

Teaching and 3D-geodata

We developed a course to teach the basics of 3D-data at schools.
