InterFlood is the fastest, easiest way to get a flood map.  All you have to do is type an address to get a map.  If you have WinTOTAL, we even give you one-click integration. Plus it's inexpensive and nationwide.

Okay, on to some boring stuff.   Many of us are skeptical in nature and we have those technical questions buzzing in our minds.   Well, here's the top frequently asked questions.

Feel free to contact us if you have additional questions.

	In which areas does InterFlood have flood map coverage?
	We have 99.96% up-to-date coverage of the entire US, its territories and protectorates.  Unlike Q3 flood maps, which cover only 1,293 counties, InterFlood flood maps cover each of the 3,141 counties in the U.S. That's over 114,000 flood maps online.  If FEMA has a map for your area, then we have it.

	How often are InterFlood flood maps updated?
	InterFlood flood maps are updated at a minimum once each month, averaging about 275 updates per month.
	Why does InterFlood show more than one map for my property location?
	This happens when FEMA produces flood maps that overlap or when a property is close to the boundary of a flood map.  Properties near the boundary of a flood map may actually be on an adjoining flood map due to inaccuracies in the geocoding methods used to determine property locations. You can view each of the maps and decide which one you want to use.  Your InterFlood map account is only decremented for a single map view.
	Why is my property placed in the wrong place on the location map?
	Geocoding software can sometimes produce property geocoordinates (latitude and longitude) that are inaccurate to a distance of 500ft.  This inaccuracy is actually very small when you consider the irregularity of property shapes, street placement, block numbering, etc.  InterFlood shows you the geocoded property placement on a location map so you can verify that the property was properly geocoded.  If your property is in the wrong location, simply click the map to adjust the property placement.
	Why doesn't InterFlood find a flood map for my property?
	Some communities do not participate in the FEMA flood mapping program.  InterFlood automatically logs any property locations for which no flood maps were found.  These logs are then sent to our data provider, FloodSource, for resolution of any problems which may have prevented InterFlood from providing a flood map.

	Why does InterFlood keep prompting me to login?
	InterFlood uses several security features of your Internet browser to prevent unscrupulous users from generating flood maps without a valid contract.  Two of these features are referer strings, and cookies.  Some firewalls block referer strings and cookies.  To use InterFlood you will need to configure your firewall to allow referer strings and cookies for InterFlood.com and alamode.com.  Be sure to make these configuration settings for the domain part of the Internet address only (i.e. use InterFlood.com instead of www.InterFlood.com)
	How do I save or print a flood map?
	To save a flood map, simply right click the map, select Save Picture As, and type in the file name. To print a flood map, simply right click the map and select Print Picture. Then click the Print button in the Print dialog.
	Can I get InterFlood on CD?
	No.  We do not offer InterFlood on CD because Internet mapping is more convenient in several ways.  Internet mapping is much more up to date than CD mapping.  FEMA flood maps change constantly.  In turn, CDs may be out of date the day they are shipped, where as InterFlood always has the most current maps made available.  CDs don't geocode your property and automatically place your subject on the correct map. InterFlood does.  Another drawback to offering CDs is that with CDs there are usually fees per state or per county.  Those additional fees aren't necessary with online mapping.
	Other than the actual flood map, what other information does InterFlood provide?
	With any InterFlood purchase, you will receive the Census Tract, Map Number, Map Panel Number, Map Effective Date, Flood Zone, Standardized USPS address, county name and community number for the properties for which you would like to retrieve a flood map.
	What are the different flood hazard zone designations and what do they mean?
	To learn more about what the different flood zone designations mean, please visit FEMA's website for a complete explanation.
	What's the source of InterFlood flood maps?
	InterFlood flood maps are scanned from official FEMA paper flood maps at 400 dpi and digitally enhanced for computer use.
	What is an Exact Match or Zip Code Fallback geocode result?
	An Exact Match means that InterFlood found exact geocoordinates (latitude and longitude) for the property address you entered.  A Zip Code Fallback means that InterFlood was unable to find the geocoordinates for the property address you entered but did find geocoordinates for the property zip code.  When this happens, InterFlood marks the center of the zip code area on the location map.  You can then simply click the correct location on the map to place your property exactly.
	What is Q3 data?
	“Q3” is digital flood data from FEMA for about 1300 counties nationwide (out of more than 3100 total). FEMA’s own web site makes it clear that Q3 data is not for individual property determinations — it was designed for community level analysis only, and was taken from their large overview maps. Yet, even though FEMA gives this clear warning, many CD and online flood map companies use Q3 data as their primary source of flood maps.
