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.

UAV #1 Track. UAS Applications and ArcPro 2.1: The Waugh Arboretum’s Evolving Process of Tree Inventorying and Management
AUTHORS: Daniel J. Myers, GIS Technician, Physical Plant Grounds and Facilities; Christopher A. Copeland, GIS Technician, Physical Plant Landscape Management – University of Massachusetts, Amherst

ABSTRACT: Urban landscapes are dynamic systems inundated by physical, chemical, and biological inputs. As UMass Amherst continues its campaign for campus development, there are inherent conflicts with its urban forest. Trees are assets to any community, each with varying degrees of worth and functionality. A tree inventory is a method to monitor changes to each individual tree and detect patterns to the collective tree population. It serves as a guide to prioritize tree maintenance, preserve valuable specimens, and communicate forest functions to stakeholders. Campus arborists currently update the tree inventory using tablets equipped with ArcPad 10.2 and TreeWorks 2015. With the implementation of UAS technology and ArcPro, campus arborists can more accurately and efficiently measure trees and observe their environment. One centimeter pixel resolution RGB imagery can aid campus arborists in efficiently calculating dendrometric variables and through time series analysis. In our presentation, we will explore the benefits of ESRI Drone2Map and ArcGIS Pro 2.1 Image Analyst extension. These applications are used to create an accurately georeferenced orthomosaic and to conduct an object-oriented classification to identify tree canopy coverage and tree genus at a forty acre study area. As GIS technology evolves, our comprehensive GIS databases functionality can increase as a tool for organizing, analysis, and reporting with ancillary data collected by UAS.

UAV #1 Track. So You Built a Multi-million Bathhouse: Assessing the Past, Present, & Future of a Beloved New England Beach Using Drones
AUTHORS: Tracy Tien, Spatial Fellow, Spatial Analysis Lab, Smith College
Jon Caris, Director, Spatial Analysis Lab, Smith College
Robert Newton, Professor of Geoscience, Smith College

ABSTRACT: Popham Beach, Maine experiences extreme shoreline and dune changes that pose potential threats to park facilities and private properties. For many years, students from Smith College make a spring trip to Popham to assess the dynamic beach processes and learn a field data collection methods. Professor Robert Newton’s geomorphology class conducts recurring ground-based surveys each year to discern the how, why, and what if’s of the sedimentation process at the beach. The Spatial Analysis Lab recently introduced aerial surveying with drones that complements the research with large-scale, high-resolution orthomosaics to offer analysis on beach erosion and restoration overtime. Analysis of drone imagery with ArcGIS confirms drone mapping is suitable for accurate shoreline monitoring. The UAV data collected also enhances the work by addressing the resiliency and adaptability of the state park to sea-level rise.
