TL;DR: In this article, the authors used repeat photography, dendrochronological analysis, field observations along elevational transects and historical documents to study tree line dynamics in a sub-Arctic model area at different temporal and spatial scales.

TL;DR: In this article, a set of 57 historical photographs taken in Tigray, and clearly displaying gully cross-sections, were precisely repeated from 2006 till 2009, showing that nearly two percent of the gully and river sections increased in cross-sectional area during the studied period, especially after 1975.

TL;DR: This approach addresses some of the major issues in object-based GIS change analysis as it is based on stable object geometry, which is necessary in decision support systems and uncertainty management strategies.

TL;DR: A new region-merging segmentation technique has recently been developed which incorporates the spectral and textural properties of the objects to be detected and also their different size and behaviour at different stages of scale, respectively, which resulted in the development of an automated, standardized classification methodology.

TL;DR: In this paper, the existence of Pleistocene rock art in North Africa is proven through the dating of petroglyph panels displaying aurochs and other animals at Qurta in the Upper Egyptian Nile Valley.
