Open Standards, Free Geodata and 3D

摘要

How can open standards and free geodata contribute to disaster management, even in 3D? Why use open standards in disaster management (DM) at all and, trickier still, why 3D? Others have touched on these questions in this column and I focus here on the reasons for using free geodata for DM, taking as example its usefulness, combination with open standards, and how this applies to 3D-analysis and visualisation.
