The objective of this web service API is to assess the expected value of coastal real estate, given sea level rise. The assessed value will combine data from NOAA's sea level rise estimates and Zillow's real estate estimates. We will have to figure out exactly what the input and output parameters should be, but we will need to calculate the time profile of real estate value under multiple scenarios. Whether that gets surfaced to the end-user of the service is still in question.
Currently the only working feature is the geocoding service, since coastal.noaa.gov is currently down. Plus we should all figure out what we need to do, and how to develop, anyway. A brief video that describes the available data (when the site is live again) is available here.
