<p><b>Daniel Tal, ASLA</b> is a registered landscape architect with over 22 years of experience. Daniel is the visualization and drone manager for DHM Design. He is the author of <b><i>SketchUp for Site Design, Second Edition</i></b> and <b><i>Rendering in SketchUp</i></b>. Daniel designs and operates 3D modeling software apps including www.suplacemaker.com and www.SketchUrbanPaint.com. He has a tutorial website at www.danieltal.com. Daniel speaks nationally on technology, provides lectures to universities and publishes blogs and articles. <p><b>Jon Altschuld, RLA</b> is a licensed landscape architect with over 12 years' experience and is the founder and principal at Chinook Landscape Architecture (www.chinookLA.com) in Denver, CO. He is also an FAA registered remote pilot, and a board member of the Professional TrailBuilders Association (PTBA). In his career he has focused on using emerging technologies such as drone data collection and 3D visualization to approach complex design issues, often in environmentally sensitive areas. He has worked on projects ranging from major transportation corridors, to non-motorized trails master plans, to floodplain and habitat restorations. Jon also teaches workshops and gives professional training on SketchUp, Vue, CAD, Lumion, and Adobe Graphics programs within the AEC community.

<p><b>A start-to-finish roadmap on incorporating drone technology into your AEC firm workflow</b> <p><i>Drone Technology in Architecture, Engineering and Construction: A Strategic Guide to Unmanned Aerial Vehicle Operation and Implementation</i> is the only process-driven, step-by-step handbook to implement drone technology in AEC workflows. It provides a comprehensive and practical roadmap for architecture, engineering, and construction firms to incorporate drones into their design and construction processes. <p>The book offers extensive information on drone data processing, and includes guidance on how to acquire, manipulate and use the various data types produced from drone flights. The creation of three-dimensional data and visualizations are covered in-depth. <i>Drone Technology</i> reviews how to select and fly drones based on data needs and initial costs, and how to collect and maintain required flight logs, licenses, and permits. <i>Drone Technology</i> uses several real-world project examples that demonstrate and explain how drones can be used to collect: <ul> <li>Full-color orthorectified imagery</li> <li>Accurate 3D point cloud and mesh models</li> <li>Topographic contours</li> <li>Digital Elevation Models (DEMs)</li> </ul> <p><i>Drone Technology in Architecture, Engineering and Construction</i> is an essential guide for a wide variety of professionals, from civil engineers to landscape architects. It provides information on professional use of drones for those just considering the technology, to those already flying drones professionally. It is an invaluable guide for anyone working in the design or construction of buildings and landscapes.
