Abstract: This report presents results of the 29 th consecutive year of fall aerial emperor goose surveys in southwest Alaska. All bird and marine mammal species were counted with emphasis on emperor geese, Pacific brant, Canada geese, and Steller’s eiders. Population estimates for emperor geese

The National Marine Fisheries Service (NMFS) conducted an aerial survey of the beluga population in Cook Inlet, Alaska, during 4-11 June 2002. The 45 hr survey was flown in a twin-engine, high-wing aircraft at an altitude of 244 m (800 ft) and speed of 185 km/hr (100 kt), consistent with NMFS

This paper aims to present a review of recent as well as classic image registration methods. Image registration is the process of overlaying images (two or more) of the same scene taken at different times, from different viewpoints, and/or by different sensors. The registration geometrically align two images (the reference and sensed images). The reviewed approaches are classified according to their nature (areabased and feature-based) and according to four basic steps of image registration procedure: feature detection, feature matching, mapping function design, and image transformation and resampling. Main contributions, advantages, and drawbacks of the methods are mentioned in the paper. Problematic issues of image registration and outlook for the future research are discussed too. The major goal of the paper is to provide a comprehensive reference source for the researchers involved in image registration, regardless of particular application areas.

Following preliminary ground surveys, microlight aircraft were used to conduct an aerial survey of African white-backed vulture (AWbV; Gyps africanus) breeding colonies in the Kimberley area, South Africa. Six colonies ranging from five to 135 km2 in area (covering a total area of 506 km2) were

-sensing technology can reduce these costs. Here, we used high-spatial-resolution aerial photographs (0.5–1.0 cm per pixel) taken from an unmanned aerial vehicle (UAV) to survey fallen trees in a deciduous broadleaved forest in eastern Japan. In nine sub-plots we found a total of 44 fallen trees by ground survey
