The map provided is dynmaic, i.e. the user may zoom and pan within a small range.
The dynamic FEMA Flood map base url is https://floodmap.nationalflooddata.com/
Endpoint
The dynmaic FEMA Flood map uses the default endpoint:
| endpoint | description |
|---|---|
| dynamic.html | Fema Flood Map |
Parameters (all required)
| value | description |
|---|---|
| key | authentication key |
| lat | latitude |
| lng | longitude |
| zoom | integer parameter between 6 (low zoom) and 17 (high zoom). Default zoom is 15. |
Note: the low zoom is intended only to allow a user to move around the map quickly. Low zoom can load slowly and polygons are simplified. Only high zooms between 14 and 17 should be used to illustrate zones.
