149 Mitigating Risk and Increasing Resilience large groups of images taken by cameras along the many flights and routes. This set of imagery data works together inside GIS to create a precise 3D model. The resulting immersive basemap forms the foundation of a digital twin. From there, the team can add an inventory of data about physical assets, trees, houses, and infrastructure. Within the digital twin, they use the artificial intelligence (AI) technique called machine learning to automatically extract details from the images, such as building outlines and changes to the shoreline. “The most exciting thing for us is what’s possible with machine learning and desktop computers now,” said Frank Pichel, partner and global field operations lead at PLACE. The aerial imagery was processed to create a positionally accurate true orthoimage of the island. addressing extreme weather, food security, and disasters,” said Stuart Minchin, director-general of SPC. In April 2024, the PLACE team was in the remote nation and collected images of Funafuti, the country’s capital. They used a drone to capture aerial images, and a spherical camera mounted to a truck to capture street-level views. This sensor pod camera with five lenses on the sides and top can also be attached to a backpack for capturing areas that can only be reached on foot. PLACE imagery data is processed to create 2D and 3D data products using ArcGIS Reality, a suite of photogrammetry software products designed to enable reality capture workflows for sites, cities, and countries.
