Building on the foundation of the bestselling first edition, Aerial Mapping: Methods and Applications, Second Edition provides you with a practical understanding of aerial photography, remote sensing, and photogrammetric mapping. The content is deliberately semi-technical and processes are discussed in a manner easily accessible to anyone regardless of their technical or scientific background. This new edition highlights the significant changes in equipment and techniques. High-speed computers, scanners, and remote sensors have changed the way mapping is done. The principles of photogrammetry, image analysis, and remote sensing have become dynamically intertwined. With the solid grounding in basic procedures that Aerial Mapping: Methods and Applications, Second Edition provides you can apply your knowledge to the special conditions of each aerial mapping project.

As the need for geographical data rapidly expands in the 21st century, so too do applications of small-format aerial photography for a wide range of scientific, commercial and governmental purposes. Small-format Aerial Photography (SFAP) presents basic and advanced principles and techniques with an emphasis on digital cameras. Unmanned platforms are described in considerable detail, including kites, helium and hot-air blimps, model airplanes, and paragliders. Several case studies, primarily drawn from the geosciences, are presented to demonstrate how SFAP is actually used in various applications. Many of these integrate SFAP with ground-based investigations as well as conventional large-format aerial photography, satellite imagery, and other kinds of geographic information. - Full-color photographs throughout - Case studies from around the globe - Techniques presented allow for image resolution impossible to match via traditional aerial photography or satellite datasets - Glossary clarifies key terms
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.
This issue of Highway Research Record is dedicated to the field of aerial surveying. Papers cover topics including electrotape measurements, geodimeters, tellurometers, stereotriangulation, aerial photography and photogrammetrics.

Originally published in 1952, this book is intended as an introductory guide to aerial mapping and photogrammetry. The main emphasis is on making maps during wartime, when accuracy is paramount and information may be minimal; Trorey had experience of this while serving with the Canadian Military Survey in WWII. This book will be of value to anyone with an interest in mapmaking.
The use of aerial photogrammetry and other related sensors to some other problems in hydrology are considered. Here it seems that such remote sensing from aircraft offers the hydrologist a feasible means to map some special events where detailed mapping is needed.
