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.

Web Apps #1 Track. Using GIS Tools to Better Manage Staff, Projects and Better Utilize Acquired Data
AUTHORS: John Diaz, Robert Nalewajk – Greenman-Pedersen, Inc.

ABSTRACT: GPI is actively utilizing in-house UAS services for a variety of project related tasks. These can vary from obtaining simple graphics for marketing/presentation purposes to complex, surveys and infrastructure assessments. Keeping track of the flights, in terms of planning, scheduling, assigning pilots and notifying Project Managers of the completion of the flight as well as data processing was becoming more difficult as more and more applications for UAS services grew. One of the biggest issues was communicating with the UAS pilots to assign projects and for them to notify staff of the status (planning, complete, etc.).

Utilizing a variety of ESRI GIS products; including Workforce, Collector, Web Apps, AGOL and Desktop, GPI was able to provide a more direct way for Project Managers to coordinate and schedule UAS flights. Through building a Web App, Managers could submit a flight request and check on the status of the flight. Through integrating the Flight Request with Workforce, the flight could be assigned to the UAS Pilot through the mobile application. Integrating the Collector application with Workforce allowed the UAV Pilot to view all details of the project as well as giving them the opportunity to edit relevant data from the field.

Once the flight was completed, a dashboard was developed to provide a quick update of the flight request status.

The discussion will also include GPI's use of Collector and Survey 123 as tools to more efficiently and effectively collect field data for a variety of applications.

UAV #2 Track. UAS Lidar and Imagery in the NERRS: Evaluating the Effectiveness of UAS Sensors and Platforms for Multi-Purpose Mapping of Marshes and Beaches in the NERRS Sentinel Site Network
AUTHORS: Kirk Waters, NOAA OCM; Sue Bickford, Wells NERR; Jamie Carter*, TBG at NOAA OCM; Nina Garfield, NOAA OCM; Andrea Habeck, Jacques Cousteau NERR; Nate Herold, NOAA OCM; Jared Lewis, San Francisco Bay NERR; Jonathan Pitchford, Grand Bay NERR; Melissa Rosa, TBG at NOAA OCM

ABSTRACT: There is a near universal need within the National Estuarine Research Reserve System (NERRS) and by other natural resource stakeholders for accurate Digital Elevation Models (DEMs) and habitat maps to support a diversity of applications. Applications include supporting sea level rise research and management and flood forecasts; evaluating the impact of specific vegetation management practices on elevation in marsh micro-environments; assessing beaches after storms for damage assessment and restoration purposes; and identifying high priority invasive and sensitive vegetation. Our intent with this project was to evaluate the effectiveness of unmanned aerial system (UAS) platforms to produce multiple mapping data and products for elevation and vegetation mapping in marshes and dune systems. We sought a UAS solution that could fly multi-spectral and lidar elevation instruments sequentially on the same platform. We contracted UAS data collection to the private sector (Quantum Spatial, Inc., and PrecisionHawk) and conducted the ground truth ourselves (NERRS and NOAA staff). We used multiple NERRS sentinel sites as test beds. Data from multiple high-resolution multi-spectral sensors and lidar elevation were acquired for three NERRS sites: Jacques Cousteau, NJ; Grand Bay, MS; and Rush Ranch in San Francisco Bay, CA. The data were evaluated on their ability to meet specifications, primarily positional accuracy and resolution, and their potential to improve habitat mapping.

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.

UAV #2 Track. UAS Management: Integrating Drone Operations in an Enterprise Setting
AUTHORS: Nate Ward, Terracon

ABSTRACT: Managing your Unmanned Aerial System (UAS) fleet, flight crews, authorizations, batteries, and records can be time consuming and tricky. Coordinating drone operations across an organization requires these aspects to be done in a management system. As a case study on choosing a management platform, we will look at the current options on the market and how they can help your organization simplify its UAS management.
