Lidar/3D Track. Topo and Bathymetric Lidar Capture for the City of New York
AUTHORS: Kristen Grady*, NYC DoITT; Jarlath ONeil-Dunne, UVM Spatial Analysis La; Drew Meren, Quantum Spatial; Michele Giorgianni, AppGeo

ABSTRACT: The City of New York has realized the importance of developing accurate and current elevation and land cover data in support of resiliency and green infrastructure initiatives. In 2010, the City acquired high accuracy, bare-earth processed Topographic LiDAR data for the full extent of New York City. This data was used to support a variety of projects such as coastal storm and sea level rise inundation, flood risk assessment, and mitigation, green infrastructure and tree canopy planning.

In 2017, the City began to collect new Bathymetric and updated Topographic LiDAR data. This new data will support City operations with data analysis, policymaking, resiliency and environmental planning. In addition, the use of the 2010 and 2017 data will be used to analyze how Hurricane Sandy and human interventions have recently altered the City’s landscape. Since 2010 the evolution of Aerial Bathymetric LiDAR (TopoBathy) has allowed for elevation data below certain depth of water in and around the City. In the Spring and Summer two aerial missions were set out onto the City to collect both the Topographic and TopoBathy LiDAR data. Collection was captured from 2 different planes. Coordination with the City, FAA, media, the weather and contractors required well organized procedures and systems between all involved. This abstract will look into these tasks during the scope development, coordination and acquisition stages.

Direct and derived products - land cover, tree canopy change, and Digital Elevation Models - will provide an unprecedented opportunity to analyze change and to support future resiliency planning.

Lidar/3D Track. Expanding Vermont Spatial Data Infrastructure with Statewide QL2 Lidar
AUTHORS: Mike Brouillette, Lidar Program Manager, Vermont Center for Geographic Information

ABSTRACT: Vermont has achieved statewide Quality Level 2 (QL2) lidar coverage in 2018, positioning the state to pursue robust Vermont Spatial Data Infrastructure (VSDI) goals previously out of reach. Primary among these goals is a statewide, 17-class land cover layer at 0.5m resolution with an overall accuracy of 90% or better. The geometric information in lidar along with the spectral information in various statewide imagery supports Automated Feature Extraction using an Object Based Image Analysis framework to produce this data. Increased data accuracy, reduced acquisition costs, and advancing technologies are increasingly enabling those responsible for finding innovative solutions to an array of Vermont’s challenges. A pre-release of the land cover data will be shown along with other current efforts (Statewide Property Parcel Mapping Program), as well as a brief overview of the lidar program and lidar-based services.

Lidar/3D Track. Vegetation Analysis in 3D
AUTHORS: Andrew Flynn, Vermont Electric Power Company

ABSTRACT: LiDAR data can be a powerful tool to support decision making at an organization, but simply viewing the data can be a cumbersome process that limits its usage to a handful of individuals. Vermont Electric Power Company (VELCO) has deployed tools in ArcGIS Online to empower users across the company by providing on demand access to LiDAR deliverables in a high performance 3D environment.
