# Digital Twin of Naval Support Activity Annapolis (NSAA), U.S. Naval Academy (USNA)
The following video was briefed at ACM SIGGRAPH 2021 conference in
*Summary*
. Versar, CEG, and a small dynamic team of partners provide NSA Annapolis(NSAA)
U.S. Naval Academy (USNA) NAVFAC and Commander of Naval Installation Command (CNIC)
with the 3D Virtual Environment (3DVE) technologies, tools, data and
visualization platform to better understand and communicate specific Courses of Actions (COAs)
that the installation might need to implement in order to be more resilient for
climate and coastal change.

This video was briefed at ACM SIGGRAPH 2021 conference in
Cartographic Birds of a Feather (BOF) session on Monday 9 August 2021.
Note that the video was recorded from a Web browser, all models and metadata
are following the open international data standard X3D.

## Overview
This effort resulted in the first simple digital twin of a Navy and Marine Corps installation.
This simple mode of both natural and built environments in 3DVE will assist with improving the
pace of technical, geospatial-based collaboration, and decision support for this and
future planning efforts on the installation.
Naval Support Activity Annapolis (NSAA), home of the United States Naval Academy (USNA),
is located at the confluence of the Severn River and Chesapeake Bay.
The campus is vulnerable to storm surge associated with major weather events as well as
localized, nuisance flooding that is primarily the result of high tides and
sustained easterly or southerly winds. Since 1929, the relative sea level in Annapolis
has risen approximately 1.06 ft, which has significantly increased the occurrences
of nuisance flooding from 2-3 times per year to 30-40 times per year and
left USNA more vulnerable to major storms such as Hurricane Isabel in 2003.
Impacts from storm surges and nuisance flooding affect daily operations through
closures of flooded roads, sidewalks and building entry points.
With greater frequency and increased amounts of water, the negative impacts
are being increasingly felt throughout USNA operations. Long-term impact,
without future action, places many of USNA’s buildings and monuments as well as the
effective execution of the mission of the Academy at risk.
## Project Team
Swift River Versar JV is assisting NSAA meet these challenges by reviewing
NSAA/USNA past studies, reports and data collection efforts and providing
planning guidance that will address sea level rise, coastal flooding, storm surge
and stormwater planning and mitigation efforts. The goal is to create a comprehensive plan,
project portfolio and year-by-year execution strategy to cohesively address these natural hazards.
## Project Implications
Climate change, sea level rise, changing weather patterns and continued subsidence
of the Mid-Atlantic land mass will continue to contribute to an increase in the
number and magnitude of coastal flooding events in the near- and long-term future
of the Annapolis region.
These conditions will continue to impact land and infrastructure and pose
significant challenges to the successful execution of the Naval Academy mission.
Protective measures at the Lower and Upper Yard as well as North Severn zone
will be necessary to reduce damage from these events and facilitate effective mission execution.
Given the imminent threat of extreme coastal and precipitation-based storm events
as well as probable permanent inundation of some land areas over time,
what adaptation and resilience measures can be taken to address present-day and
likely 2035, 2065 and 2100 impacts in order to protect Mission-Essential infrastructure and facilities
to ensure the successful execution of mission critical and base support activities at the U.S. Naval Academy?
*Technical Details*
. TODO, describe:
*
UAV lidar scanning from campus flyovers,
*
UUV sonar scanning of shoreline,
*
Handheld LIDAR scanning in utility tunnels,
*
Geometry decimation and distillation,
*
Model publication on Web using Extensible 3D (X3D) Graphics International Standard.
