Paris in 3D with QGIS and three.js

Some time ago, I saw this article about using the Qgis2threejs plugin to export a QGIS map as a 3D visualisation in the browser, thanks to three.js and WebGL. When I recently tried to follow the post to reproduce the results, I had some problem sourcing the data (related to Vienna, Austria) so instead I searched for data related to Paris to create a similar scene. Here is the result corresponding to the screenshot above and another one with aerial photos, both showing the Montmartre area of Paris.

HAZUS-MASAS

HAZUS-MASAS is not a magic incantation used by GIS wizards, just the name of an interesting project I was involved with (on the data engineering side of things) when I worked at Galdos Systems, back in Vancouver. I just saw CEO Ron Lake has written an article about it on the company’s blog. In short, the goal of the project was to enable the distribution of HAZUS files (created with a FEMA-provided ArcGIS plugin for the estimation of potential losses from natural disasters, like earthquakes or floods) through the Canadian Multi-Agency Situational Awareness System (MASAS), used by emergency managers. Some of the UI was done with the ArcGIS Viewer for Flex (screenshot above): In the backend, it connected with INdicio (a CSW-ebRIM implementation), which provided metadata about indicators extracted from HAZUS files, as well as the contents of the indicators themselves, stored as KML documents.
