Ich versuche, einen vollständigen Satz von FEMA Hochwasserdaten für ein internes Projekt zu erhalten. Gibt es eine Quell-URL, um die FEMA DFIRM als GIS-Daten für die gesamten Vereinigten Staaten herunterzuladen? <\/P>

<\/P>

Vielen Dank.<\/P>

This link does not exist. Is there a new one? It seems that the NFHL GIS data is no longer available to download directly.

National Flood Hazard Layer (NFHL) | FEMA.gov says " Technical GIS users can also utilize a series of dedicated GIS web services that allow the NFHL database to be incorporated into websites and GIS applications." and provides this link:

FEMA: Mapping Information Platform: NOPAGETAB_NFHLWMS

But as far as I can tell, that just send you to a map viewer, and download to an image or pdf. However, buried in the fine print is:

For more information, please call or email a FEMA Map Specialist at 1-877-FEMA-MAP or FEMAMapSpecialist@riskmapcds.com.

OMG THANK YOU!!!! I don't know why every link I was finding was either outdated or didn't have download capabilities. It appears even the WMS links are outdated. Thanks so much !!

This link is no longer available 😅

Not exactly the same dataset but would this work for your purposes? I use it as an input for a classification model.
