Abstract:
The photogrammetric mapping process at the first stage requires planning of aerial photography. Aerial photographs quality depends on the successfull photographic mission specified by requirements that meet not only Lithuanian needs, but also the requirements of the European Union. For such a purpose the detailed specifications for aerial photographic mission for mapping urban territories at a large scale are investigated. The aerial photography parameters and requirements for flight planning, photographic strips, overlaps, aerial camera and film are outlined. The scale of photography, flying

During the development of water resources the characteristics of excitement, direction, and flow velocity, depth, points of bottom, temperature and chemical composition of water is to be taken into account. Some of these indicators are determined through the results of measuring single aerial photographs and their stereoscopic pairs. Making aerial photography (APS) of water surface on technology for topographic land survey enables obtaining only single overlapping aerial photographs, as the water surface is in constant motion.

Therefore, there is concern that an increase in the number of images taken affects the quality and process of inspections. Among the defects qualitatively detected in visual inspections, blurring is a serious one, despite its low rate of appearance. However, the blurry images detected in the visual inspections can only be solved by the take another photograph. For this reason, it is not acceptable for any blurry images to be missed in the visual

This study demonstrates the value of historical aerial photographs as a source for monitoring long-term landslide evolution, which can be unlocked by using appropriate photogrammetric methods. The understanding of landslide mechanisms requires extensive data records; a literature review identified quantitative data on surface movements as a key element for their analysis. It is generally acknowledged that, owing to the flexibility and high degree of automation of modern digital photogrammetric techniques, it is possible to derive detailed quantitative data from aerial photographs.

For a given level of precision within a particular stand, Bayesian methods reduced the required field sample size up to 50% using all or half of the prior information available.

Changes in land use were determined and correlated with accessibility, appropriate low technology methods being used to make it easy to extend the investigation to other areas without incurring great expense. A test area of 750 sq km was chosen located in Kaduna State of Nigeria. The geography of the area is summarised together with the local knowledge which is essential for accurate photo interpretation.

Abstract:
Since 2014, a team of scientists from the Raincoast Conservation Foundation (2022-2024), Ocean Wise Conservation Association (2014-2022), NOAA (2014-2017) and SR3 (2017) have collected aerial photographs of Northern Resident killer whales (NRKW) in the waters around northeastern Vancouver Island annually (August-September) in order to monitor body condition. In 2019, 2022, 2023 and 2024, additional field work was conducted on the Central Coast of British Columbia in June and/or July. Body condition was assessed from aerial photographs by calculating ‘eye patch ratios’ (Fearnbach et al. 2019),

Abstract:
The Cache Valley region in northern Utah and southern Idaho contains and is surrounded by several large, hazardous faults which pose significant earthquake risk. The 40-mile-long (65 km) East Cache fault zone (ECFZ) and the 35-mile-long (56 km) West Cache fault zone (WCFZ) bound the Cache Valley graben and both show evidence of large surface-faulting earthquakes in the late Quaternary. Other hazardous faults in the Cache Valley region include the intrabasin Dayton-Oxford fault, the Mantua area faults within the Wellsville Mountains, and the James Peak fault at the very southern end of the ECFZ
