The paper focuses on the automatic geometric corrections module of the STORM automatic optical satellite image processing chain and its adaptation to very high resolution (VHR) multispectral images. In the automatic ground control points (GCPs) extraction sub-module a two-step algorithm that utilizes vector roads as a reference layer and delivers GCPs for high resolution images with near pixel accuracy was initially implemented. Super-fine positioning of individual GCPs onto an aerial orthophoto was introduced for VHR images. The enhanced algorithm is capable of achieving positional accuracy of approximately 1.5 pixels on WorldView-2 data. In the case of RapidEye images, the accuracies of the physical sensor model reach sub-pixel values at independent check points. When compared to the reference national aerial orthophoto, the accuracies of WorldView-2 orthoimages automatically produced with the rational function model reach near-pixel values. On a heterogeneous set of 41 RapidEye images the rate of automatic processing reached 97.6%.

This chapter is part of the edited volume entitled Moving Places, co-edited by N. Gregorič Bon and Jaka Repič and published by Berghahn Books. The book focuses on physical movements of people, places, things and ideas with their spatial and temporal implications. It explores interrelatedness between practices and politics of place-making and movement as a mode of mobility and immobility. The contributions ethnographically explore the specificities of a given region, address issues of place-making, the topographic and social positioning of its inhabitants, the production of centrality and marginality, and discuss the returning as either conceptual, physical or symbolic movement, with the attendant notions of roots, rootedness and locality. The chapter Rooting Routes focuses on various modes of movement and non-movement of migrants who claim to originate from one of the villages of the bilingual (Albanian and Greek speaking) area in Southern Albania. It explains how migrants, through their continuous movements, generate their sense of rootedness and belonging to their natal village. Their feelings of belonging are paradoxically based on their sense of rootedness in a particular locale, as well as on their continuous movements and migrations.

A fully automated procedure for orthorectification of optical satellite images, acquired by linear scanners, is presented. The paper describes the whole automatic orthorectification process, which comprises four basic modules: a module for extracting and preparing the metadata, a module for automatic extraction of ground control points (GCPs), a module for the calculation of the geometric model parameters, and a module for orthorectification. Experiments and results on a test set of RapidEye images are also presented. The experiments evaluate the procedure for automatic extraction of GCPs, the geometric model, the elimination of gross errors, and the positional accuracy of the orthoimages. The results indicate that the automated procedure produces orthoimages with a positional accuracy of about one pixel or better, even if several gross errors are present among the automatically extracted GCPs.

Clock-time differentiates and systematizes in a way rarely endorsed by small-scale societies, where the tendency is to reject systematization and hierarchy based on the measurement of time. Taking the lead from the Ambonwari, Papua New Guinea, the author introduces the concept of egalitarian temporality produced by never ending competition between different individuals and groups, and their temporalities. The villagers are themselves responsible for exchanging periods and ways of being in both their environment and society, and they actively participate in dramatic episodes intended to cut into their existent ways of life. These ‘cuts’ then exchange one period for another and are then perceived as changes in mode of existence. The author argues that time in the Sepik and egalitarian small-scale societies in general is very much agentive and thus possessed, held and seen by individuals and groups, with periods defined by and organized around future oriented projects.

Systematic archaeoastronomical research conducted in several regions of Mesoamerica has revealed the existence of architectural orientations corresponding to major and minor extremes of the Moon (also known as standstill positions) on the horizon. Particularly indicative are the results of quantitative analyses of alignment data from the Maya Lowlands, disclosing a prominent group of orientations that can be convincingly related to the major lunar extremes. The astronomically-motivated intentionality of these alignments is additionally supported by contextual evidence, particularly significant being the fact that most of them are concentrated along the northeast coast of the Yucatán peninsula, where the lunar cult is known to have been important. Since the lunar orientations are regularly associated with those corresponding to the solstitial positions of the Sun, it is very likely that particular attention was paid to the full Moon extremes. This contribution also presents some independent evidence that sheds light on the cultural significance of lunar orientations.
