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 memorandum describes the computer program used operationally at the National Environmental Satellite Center (NESC) to determine the attitude of a TIROS operational Satellite (TOS)). It includes background information of historical interest, specific details of the problem and its solution, and thoughts about future approaches. It is intended as a description of this part of the NESC operation and as an introduction to the more esoteric program documentation

Sponsored by the Committee on Advanced Data Collection and Management Systems of ASCE. This casebook offers examples of civil engineering practices in the acquisition and use of data obtained with advanced aerial and ground-based remote collection systems. The first section deals with remote sensing imagery and data utilization and applications to water resources site and route selection, environmental inventory, land use, and facilities. Specific applications include photobathymetry, landsat imagery, and energy-loss surveys using thermalØinfrared technology. Noncontact and contact data collection and data relay systems are reviewed, along with surface temperature mapping, photogeodesy and hydrologic telemetry from remote areas. The final section presents discussions on data processing and its applications to both data organization and information extension.
