UAV #1 Track. Drones for High Accuracy Mapping and 3D Modeling, Photogrammetry, LiDAR and Beyond
AUTHORS: Tayler Engel, GIS Analyst and Drone Pilot, ARE-AirShark

ABSTRACT: Drone technology has advanced rapidly in the past few years allowing for LiDAR and advanced photogrammetry techniques to be readily available for a wide spectrum of projects. This presentation will dive into the world of drones and the various sensors available to create survey grade data. When to use LiDAR over photogrammetry and what benefits you can expect to receive out of both methods will be discussed in detail. A variety of projects will be displayed where multiple sensors were used, from mapping of campuses using photogrammetry to environmental mapping of shorelines with LiDAR. 3D modeling of bridges and buildings using LiDAR and photogrammetry will also be discussed in this presentation.

3D Track. 3D Solar Rating for Cambridge Street Trees
AUTHORS: Katie Grillo, City of Cambridge, MA

ABSTRACT: The City of Cambridge has nearly 30,000 street trees that are maintained by the City's Department of Public Works (DPW). DPW was interested in reviewing their watering plans and also investigating tree mortality in relation to a tree's location. ArcGIS Pro tools and models were used with both LiDAR and 3D multipatch buildings to determine how much sunlight each street tree receives throughout the summer. As a way to make the results of this study more accessible to city staff, the solar rating is incorporated into the street tree data and displayed in a 3D web scene on ArcGIS Online.

3D Track. NYS Elevation Data: Lifecycle on Collecting, Reviewing, and Sharing Elevation Data
AUTHORS: Jeffrey Langella, New York State Information Technology Services - GIS Program Office

ABSTRACT: This presentation will highlight how New York State is working with other County, State, and Federal Agencies on where to collect Elevation Data. A high level overview on how the data is reviewed for quality and accuracy using several different GIS packages. The end of the presentation will focus on all the products we make available free of charge. These products include bare earth DEMs, Hillshade, Contours, and LAS Point Clouds. We will focus on how we make all of this data available to the public via direct download and web services.

3D Track. 3D Nation Elevation Requirements and Benefits Study
AUTHORS: Dan Walters, USGS

ABSTRACT: The National Oceanic and Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS) are gathering information from users across the Nation to improve the availability and consistency of 3D elevation data, including both terrestrial and bathymetric data, for the United States and its territories. The 3D Nation Elevation Requirements and Benefits Study will shape the future of Federal elevation data programs.
A previous and similar study conducted by USGS in 2012, the National Enhanced Elevation Assessment resulted in the formation of the 3D Elevation Program (3DEP). The presentation will review the progress and results of 3DEP; provide detailed information about the information being gathered now; and an overview of how the information will be used to improve 3DEP in the future.

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.

UAV #2 Track. Beyond the Drone

ABSTRACT: Small Unmanned Aerial Systems (sUAS) aka. Drones have been in use for several years and users have found many uses for data that can be produced using these systems. These applications range from basic imagery for marketing or personal use to more advanced applications such as orthophoto rectification or topographic modeling. This presentation will focus on the photogrammetric application know as Structure for Motion (SfM) and how sUAS imagery can be used to create ground surface model and 3D models of other objects such as tanks, towers and piers.
