Comment: Good article - I enjoyed seeing this topic covered in an international disaster response organization publication. However, one thing. In reference to the first sentence of the third paragraph, I'd like to offer a correction. When talking about the creation of Crisis Mappers, Dr. Meier states the concept of remote disaster mapping by volunteers was invented by what is now the Crisis Mapping organization when he states (emphasis added): "That’s because it had never been done before and it wasn’t even started by humanitarian organizations." Ah, not so fast. I know we are out here in the sticks, but a little old organization by the name of the MnGeo EPC beat Crisis Mappers to the core concept by almost a year when EPC volunteers reacted to record flooding in the Red River Valley of the North during March of 2009. In that instance, an extensive series of continuously updated 1KM and 10KM U.S. National Grid maps showing flood extent and location of critical infrastructure was produced for the entire valley north from Fargo-Moorhead to the Canadian Border. Furthermore, that system employed its own online viewer which allowed responders to search and download available maps by location. All implemented remotely, all implemented by volunteers.
