All Hazards Portals/Websites

Recommended Posts

I am doing some research on All Hazards Portals across the US. These are sites which gather GIS data on local, regional, or state levels of flood, landslide, sinkhole, tornado, hurricane, wild fire, ice and snow storms, etc. I have found a few, but they seem to be buried within other websites. Although I am focusing primarily on flooding, I would like to know where the best sites and portals for this information are located. Any help would be greatly appreciated. Thanks

I'm in GIS - as well as another forummer, Spartan - but besides FEMA flood zone data I am not familiar at all with meteorological or geological data. That is quite an extensive project you are working on - perhaps NOAA has some county level data recording instances of such events?

This project will be pretty extensive, but during the preliminary phase I am just trying to locate portals and sites which make GIS data available and how the site brings the data together, what kind of permissions are given for users, what kind of map tools are available like zoom, info etc. A good example of sites I am looking for would be:

For Charlotte NC - FEMA data is available, you could search for 'FEMA GIS data' or via a state gis data repository site. As for Charlotte Co FL, I don't know where they obtain the wind hazard data, perhaps NOAA or maybe even locally produced.

Alot of what you mentioned will be hard to find.

Something you didn't metion, but might be interested in is avalanches. They keep track of this data out west, but I undertand it to be very hard to get a hold of. Might be worth looking into though.

For FEMA flood data you can use this site, but i think you have to pay: http://www.esri.com/data/download/fema/index.html

Most local governments have FEMA Flood data if they have GIS, even if it isn't on their IMS site.

The Universtiy of SC has a pretty good hazards research lab, which you can find here: http://www.cas.sc.edu/geog/hrl/scemdmain.htm -- You might contact them regarding some of your info requests.

In SC you can use the SC Emergency Mnagement Division They seem to have alot of information, and some of it may include GIS data.

I can't guarantee any of these places will give you data for free, but its a start.
