It 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.
PS: I have my own consultancy and love to work on interesting problems. I have helped several startups and established companies deploy innovative GIS and Data Engineering solutions.
