NOAA Office for Coastal Management Coastal Inundation Digital Elevation Model: Los Angeles/Oxnard (CA) WFO - Los Angeles and
Ventura Counties
Dataset Identification:
Resource Abstract:
This digital elevation model (DEM) is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration
Office for Coastal Management's Sea Level Rise and Coastal Flooding Impacts Viewer. The DEMs created for this project were
developed using the NOAA National Weather Service's Weather Forecast Office (WFO) boundaries. Because the WFO boundaries can
cover large areas, the WFO DEM was divided into smaller DEMs to ensure more manageable file sizes. The Los Angeles/Oxnard
(CA) WFO DEM was split into two smaller DEMs. They are divided along county lines and are: 1. Los Angeles/Oxnard (CA) WFO
- Los Angeles and Ventura Counties 2. Los Angeles/Oxnard (CA) WFO - Santa Barbara and San Luis Obispo Counties This metadata
record describes the DEM for Los Angeles/Oxnard (CA) WFO - Los Angeles and Ventura Counties. The DEM includes the best available
lidar data known to exist at the time of DEM creation for the coastal areas of Los Angeles and Ventura counties, that met
project specifications. The DEM is derived from LiDAR data collected for the California Coastal Conservancy between 2009 and
2011. Hydrographic breaklines used in the creation of the DEM were obtained from the California Coastal Conservancy. The DEMs
are hydro flattened such that water elevations are less than or equal to 0 meters. The DEM is referenced vertically to the
North American Vertical Datum of 1988 (NAVD88) with vertical units of meters and horizontally to the North American Datum
of 1983 (NAD83). The resolution of the DEM is approximately 5 meters.

purpose:
The NOAA Office for Coastal Management has developed high-resolution digital elevation models (DEMs) for use in the Center's
Sea Level Rise And Coastal Flooding Impacts internet mapping application. These DEMs serve as source datasets used to derive
data to visualize the impacts of inundation resulting from sea level rise along the coastal United States and its territories.

evaluation Method Description
The DEM is derived from the source lidar data. Horizontal accuracy testing is not performed on the DEM. Lidar source data
assumed to meet 1 meter horizontal accuracy.
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description
The DEM is derived from the source lidar data. Vertical accuracy is not tested on the DEM. Project specifications require
all source lidar data used in constructing the DEM to meet FEMA Specifications for Flood Hazard Mapping.
Completeness Commission
evaluation Method Description
A visual qualitative check was performed to ensure data completeness. All available lidar data known at the time of DEM creation
that meets project specifications has been used to develop the DEM. Known data gaps may exist where lidar coverage was incomplete.
