The book focuses on the techniques for UAV-based 3D mapping and its applications in varying fields since the explosive development of UAV-based photogrammetric 3D mapping and their wide applications from traditional surveying and mapping to other related fields have been witnessed in photogrammetry and remote sensing. In the last decade, unmanned aerial vehicle (UAV) images have become one of the most important remote sensing data sources for photogrammetric 3D mapping. Besides, the rapid development of recent techniques, e.g., SfM (Structure from Motion) for off-line image orientation, SLAM (Simultaneous Localization and Mapping) for on-line UAV navigation, and the deep learning (DL) embedded 3D reconstruction pipeline, has promoted UAV-based 3D mapping towards the direction of automation and intelligence. It is really worthy to collecting the cutting-edge techniques and reporting their promising applications.

The concept of remote sensing as a way of capturing information from an object without making contact with it has, until recently, been exclusively focused on the use of Earth observation satellites. The emergence of unmanned aerial vehicles (UAV) with Global Navigation Satellite System (GNSS) controlled navigation and sensor-carrying capabilities has increased the number of publications related to new remote sensing from much closer distances. Previous knowledge about the behavior of the Earth's surface under the incidence different wavelengths of energy has been successfully applied to a large amount of data recorded from UAVs, thereby increasing the special and temporal resolution of the products obtained. More specifically, the ability of UAVs to be positioned in the air at pre-programmed coordinate points; to track flight paths; and in any case, to record the coordinates of the sensor position at the time of the shot and at the pitch, yaw, and roll angles have opened an interesting field of applications for low-altitude aerial photogrammetry, known as UAV photogrammetry. In addition, photogrammetric data processing has been improved thanks to the combination of new algorithms, e.g., structure from motion (SfM), which solves the collinearity equations without the need for any control point, producing a cloud of points referenced to an arbitrary coordinate system and a full camera calibration, and the multi-view stereopsis (MVS) algorithm, which applies an expanding procedure of sparse set of matched keypoints in order to obtain a dense point cloud. The set of technical advances described above allows for geometric modeling of terrain surfaces with high accuracy, minimizing the need for topographic campaigns for georeferencing of such products. This Special Issue aims to compile some applications realized thanks to the synergies established between new remote sensing from close distances and UAV photogrammetry.

Advances in high spatial resolution mapping capabilities and the new rules established by the Federal Aviation Administration in the United States for the operation of Small Unmanned Aircraft Systems (sUAS) have provided new opportunities to acquire aerial data at a lower cost and more safely versus other methods. A similar opening of the skies for sUAS applications is being allowed in countries across the world. Also, sUAS can access hazardous or inaccessible areas during disaster events and provide rapid response when needed. Applications of Small Unmanned Aircraft systems: Best Practices and Case Studies is the first book that brings together the best practices of sUAS applied to a broad range of issues in high spatial resolution mapping projects. Very few sUAS pilots have the knowledge of how the collected imagery is processed into value added mapping products that have commercial and/or academic import. Since the field of sUAS applications is just a few years old, this book covers the need for a compendium of case studies to guide the planning, data collection, and most importantly data processing and map error issues, with the range of sensors available to the user community. Written by experienced academics and professionals, this book serves as a guide on how to formulate sUAS based projects, from choice of a sUAS, flight planning for a particular application, sensors and data acquisition, data processing software, mapping software and use of the high spatial resolution maps produced for particular types of geospatial modeling. Features: Focus on sUAS based data acquisition and processing into map products Broad range of case studies by highly experienced academics Practical guidance on sUAS hardware, sensors, and software utilized Compilation of workflow insights from expert professors and professionals Relevant to academia, government, and industry Positional and thematic map accuracy, UAS curriculum development and workflow replicability issues This book would be an excellent text for upper-level undergraduate to graduate level sUAS mapping application courses. It is also invaluable as a reference for educators designing sUAS based curriculum as well as for potential sUAS users to assess the scope of mapping projects that can be done with this technology.

"Photogrammetry with unmanned aerial vehicles (UAVs or drones) is a rapidlymaturing technology. Being versatile and inexpensive, it has the potentialto offer solutions in a wide range of applications, such as forestry inventory, precision agriculture, flood hazard assessment, pollution monitoring, land survey, and integrity assessment of industrial facilities. Written in the form of a fieldguide, this book explains, in easy-to-understand language, basic concepts ofphotogrammetry and spatial data, and techniques for mosaicking drone photos.The book is not intended as a complete "do-it-yourself" guide, but after reading it, you get a good sense about what hardware and software parts you will need toassemble a drone system on your own. Or if you have the funds, simply purchasea commercial product and follow the steps laid out in the book to design yourapplication. Towards that end, you will find the survey of industrial leaders ofenvironmental drone applications particularly useful.The author of the book, Kike Calvo, is an experienced National GeographicCreative photographer. The explanation of technical jargons is based on his ownexperience and interviews with his colleagues. Some of the questions and answersare included in the book. These are questions you probably would have and Calvohas already got expert answers for you. I find this style of writing quite effective, injecting liveness into what otherwise could be dry reading.UAV photogrammetry is not just about obtaining pretty pictures. To realize itspotential you must "georeference" the pictures, produce an "orthomosaic," andmake "3D point clouds." Read the book to find out what all these mean, and muchmore."Foreword by Xuhui Lee.

This book discusses about a generic approach of the use of digital camera and light weight unmanned aerial vehicle (UAV) as photogrammetry tool for speeding up the process of acquiring aerial data. There were three experiments has been carried out in this study. All UAV images were processed using photogrammetry technique. There were two main photogrammetric results has been produced in this research such as digital elevation model and digital orthophoto. The results of this study also showed that the differences of DEM and digital orthophoto between both methods are not significant. We also investigate contour line behavior of landslide area and perform calculation of area and volume at the landslide area. The results of the study showed that the integration between digital camera and UAV are capable of producing digital orthophoto and capable of determining the excavated volume of the simulated model. Based on the results, UAV is useful for are many applications such as urban planning, data infrastructure of landslide risk area, forestry mapping, river surveillance and flood surveillance.

Since the early 1990s, unmanned aircraft systems (UAS) have operated on a limited basis in the National Airspace System (NAS). Until recently, UAS mainly supported public operations, such as military and border security operations. The list of potential uses is now rapidly expanding to encompass a broad range of other activities, including aerial photography, surveying land and crops, communications and broadcast, monitoring forest fires and environmental conditions, and protecting critical infrastructures. UAS provide new ways for commercial enterprises (civil operations) and public operators to enhance some of our nation's aviation operations through increased operational efficiency and decreased costs, while maintaining the safety of the NAS.
