VAMLIS GeoCon 2024

Abstract:
Challenge: Using lidar to derive the built environment presents many challenges, including lack of definition, imperfect methods to determine roof points, and levels of accuracy and precision.

Solution: Our Connecticut Statewide Lidar and Orthoimagery project demonstrates how creating complete 2D and 3D building data overcame these challenges to support a holistic approach to urban planning, infrastructure development, historic planning, and disaster management. Discussion will include the integration of manual and automated processes to confirm accuracy and completeness of building footprints.

Results: The presentation will demonstrate:
• How the incorporation of diverse data sources, including lidar point clouds and orthoimagery, enriches the dataset and enhances its utility across various applications including emergency response, urban planning, viewing shed analysis, and reducing the need for site visits.
• Through careful review and attribution, the data becomes a valuable resource for understanding the spatial distribution and characteristics of buildings.
• Through quality assurance measures including spot checks on complex buildings to verifying classification consistency, data becomes reliable and actionable.
• Additionally, the presentation will provide an example of a downstream client use in the realm of historic preservation.
