Engineering geologists generally are trained as geologists, and they commonly have a background focused on the geologic and environmental factors that affect engineering design and construction. Their expertise also requires knowledge in soil and rock mechanics, groundwater, and surface water hydrology. The role of an engineering geologist is to understand the complexities of natural phenomena and geologic materials, and to describe them in a way that is readily usable in an engineering project (Juang et al., 2016). When an engineering geologist tries to understand the natural environment and the response of the natural environment to engineering activities, he/she needs to employ a variety of tools. Photogrammetry and Remote Sensing are amongst the most frequently used tools used by engineering geologists because these techniques readily provide low-cost and time dependent data for large and inaccessible areas. In recent years, the availability and importance of these techniques have increased due to rapid technological developments.

Photogrammetry and Remote Sensing is the art, science, and technology of obtaining reliable information from noncontact imaging and other sensor systems about the Earth and its environment, through recording, measuring, analyzing and visualisation (www.isprs.org). The imaging platforms in photogrammetry include terrestrial (close-range photogrammetry), unmanned aerial vehicles (UAVs), aeroplanes and satellites. With recent developments in electro-optical technologies, the sensors range from low cost optical devices (for example, smartphone cameras) to satellite pushbroom cameras, Synthetic Aperture Radar (SAR), aerial (LiDAR) and terrestrial (TLS) laser scanners, thermal and hyperspectral cameras. This diversity in data collection methods and platforms, together with advancements in data processing and analysis algorithms, have broadened the application fields of photogrammetry by providing higher data density and resolution, and better modelling and visualisation methods. In addition, availability of low cost and easy-to-use software has made it possible for many non-experts (non-photogrammetrists) to use the technology efficiently in their engineering and research projects such as optimum route and site selection, tunnel and dam construction, or mining processes.

A collection of papers regarding current tools and methods, and state-of-the-art approaches for the use of photogrammetric techniques in engineering geology and geotechnical engineering would give insights to allow researchers to better appreciate and analyse the opportunities in this field. Papers on topics related to the main theme, “Photogrammetry in Engineering Geology: Tools, Methods and Applications,” such as those listed below (not an all-inclusive list), are welcome.
