    dct:description """Riverine Depth Grids generated by FEMA from 5m DEM obtained by USGS and Stream/River Gauges.  Includes both Modeled Preliminary Observations and Modeled Forecast.Modeled
Preliminary Observations: 

o   Based on
observed Water Levels at stream gauges interpolated along rivers, down-sampled
to 5m resolution DEM

o   Depth grids
updated with new observed peak crest as they become available

o   Will include
High Water Mark information as it becomes available

o   Extents
validated with remote sensing

o   Use for
determining damage levels on specific structuresModeled
Forecast: 

o   Based on AHPS
Full Period Maximum Forecast Water Levels at stream gauges interpolated at 500m
spacing along rivers, down-sampled to 30m resolution DEM

o   Depth grids are
a snapshot each day of the peaks of available forecast data

o   Extents
validated with remote sensing

o   Use for
situational awareness, structures exposed, and population exposed to flooding
eventsDetailed Methodology documentation can be found here:  https://geoplatform.maps.arcgis.com/sharing/rest/content/items/aed98ac13fa14d68abdd959443bdfd13/data""" ;
