This would intensify the already-intensifying impact of storm surges generated by hurricanes and other weather-related events. With more extreme weather due to climate change, NOAA expects increases in coastal flooding and shoreline erosion, as well as changes in local wildlife abundance and migration patterns.\r\n\r\nLocated on the Chesapeake Bay\u2019s eastern shore and with an average elevation of only about three feet (0.9 meters) above sea level, the city of Crisfield, Maryland, has high flooding risk. In 2012, a storm surge from Hurricane Sandy flooded most of the city, highlighting issues that are being tracked by Chesapeake Bay Program partners such as the US Geological Survey and NOAA. Using ArcGIS Pro, ArcGIS Online, and 3D landscape visualization, Chesapeake Bay Program partners created a digital twin of Crisfield to help the flood mitigation team develop a flood adaptation assessment to enhance community resilience."},{"acf_fc_layout":"image","image":678832,"image_position":"left","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"<h2>Digital Twin Shows Flooding Scenarios<\/h2>\r\nThe Chesapeake Bay Program team used 3D Basemaps to create the digital twin and employed ArcGIS Pro to generate the 3D terrain, buildings, and vegetation from lidar data and digital building footprints. Dr. Andr\u00e9 de Souza de Lima and his colleagues at George Mason University\u2019s Flood Hazards Research Lab developed flood scenarios based on NOAA\u2019s coastal high-tide flooding mapping methodology.\r\n\r\n\u201cCrisfield\u2019s digital twin enables users to see the extent of flooding under different hazard and adaptation scenarios,\u201d said John Wolf, a US Geological Survey geographer and the GIS team leader for the Chesapeake Bay Program. Wolf\u2019s team oversees landscape monitoring and modeling while leading the development of related data communication and visualization products.\r\n\r\nTo help show potential flooding impacts to buildings and other important local assets in the digital twin, the team downloaded building footprints and lidar data from the <a href=\"https:\/\/imap.maryland.gov\/\">MD iMAP Portal<\/a>, Maryland\u2019s enterprise GIS resource. The team also used property data from iMAP to add parcel-scale valuation data to the basemap."},{"acf_fc_layout":"image","image":678852,"image_position":"right","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"\u201cThe building footprints were enhanced with additional attributes originating from parcel data through spatial joins,\u201d Wolf said. \u201cAs a result, we were able to approximate the total assessed value of buildings that could be impacted under various flooding scenarios.\u201d"},{"acf_fc_layout":"content","content":"<h2>Optimizing 3D Visualizations<\/h2>\r\nThe team published 3D visualizations to ArcGIS Online, with animated water and atmospheric effects added in Scene Viewer. Because the team members also wished to show historical context for the city, which was incorporated in 1872, they used maps from 1897 that had been created for the fire insurance industry to exhibit streets, buildings, and other details.\r\n\r\nTo help with community resilience planning, the City of Crisfield flood mitigation team and others can use several interactive 3D visualizations that Wolf\u2019s team developed based on insight from scientists from The Nature Conservancy, the University of Maryland Environmental Finance Center, George Mason University, and the US Environmental Protection Agency. As examples, one visualization shows the extent of flooding and impacted buildings from a 1.5-foot (0.46-meter) water-level hazard while another illustrates the effects that would be expected if the city faced a storm comparable to Hurricane Isabel, which flooded large sections of Maryland\u2019s eastern shore in 2003."},{"acf_fc_layout":"image","image":678862,"image_position":"left","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"Using ArcGIS Pro and Site Scan for ArcGIS, the Chesapeake Bay Program team is also collaborating with the Chesapeake Conservancy to develop an integrated mesh dataset to further improve realism. \u201cThe current version of the Crisfield scenes uses 3D building and vegetation models that approximate the vertical landscape structure,\u201d said Wolf. \u201cBut an imagery-based integrated mesh version will present a more authentic depiction of the city.\u201d\r\n\r\nWhile this digital twin approach to studying coastal flooding is relatively new, it could be applied to communities all around the bay and its tributaries\u2014an area that represents 11,684 miles (18,804 kilometers) of shoreline and 4,480 square miles (7,210 square kilometers) of surface area. In fact, a similar project is underway in Norfolk, Virginia.\r\n\r\n\u201cI hope these examples will serve as prototypes for other communities along the Chesapeake Bay coastline at risk of sea level rise,\u201d said Wolf."},{"acf_fc_layout":"sidebar","layout":"standard","image_reference":null,"image_reference_figure":"","spotlight_image":null,"section_title":"","spotlight_name":"","position":"Center","content":"See an ArcGIS StoryMaps <a href=\"https:\/\/gis.chesapeakebay.net\/viz\/crisfield\/\">story about Crisfield\u2019s digital twin<\/a>.","snippet":""}],"references":null},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v25.9 (Yoast SEO v25.9) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Digital Twin Shows Climate Vulnerability in Chesapeake Bay City | Summer 2024 | ArcNews<\/title>\n<meta name=\"description\" content=\"Crisfield, Maryland, has high flooding risk.
