The Possible Use of Ancient Tower Tombs as Watchtowers in Syro-mes...

By: J. Okkonen; M. Törmä; K. Silver; M. Silver; M. Nuñez

Description: Department of Archaeology, Mardin Artuklu University, Mardin, Turkey. Traditionally polygonal tower tombs dating from the Greco-Roman era, especially found in the area of Syro-Mesopotamia, have only been treated as funerary structures without discussion of their other possible purposes. In this paper we wish to inquire whether they had other functions as well. The most famous examples of these types of tombs are situated in Palmyra in Syria. They are built...

By: T. Hakala; O. Nevalainen; S. Kaasalainen; A. Krooks

Description: Department of Photogrammetry and Remote Sensing, Finnish Geodetic Institute, P.O. Box 15, 02431 Masala, Finland. In this article, we have studied the incidence angle effect on Terrestrial Laser Scanning (TLS) intensity. In previous tests, it has been found that the backscattered intensity of an object affects the incidence angle effect. We made additional experiments to investigate the potential mixing of distance and incidence angle effects and the role o...

The Model of Wheat Yield Forecast Based on Modis-ndvi – a Case Stu...

By: G. Zhou; H. Chen; H. Zhang

Description: CMA/ Henan Key Laboratory of Agro-meteorological Safeguard and Applied Technique, Zhengzhou 450003, China. The yield estimation models on a regional scale are generally constrained by the lack of spatially distributed information on major environmental. The utilization of remote sensing data with various spatial and temporal resolutions can settle this problem. The NDVI, which retrieved from satellite remote sensing, was adopted to forecast winter wheat yi...

By: J. Göpfert; F. Rottensteiner; C. Heipke

Description: Institute of Photogrammetry and GeoInformation, Leibniz Universität Hannover, Germany. In order to tackle the problem of consistently integrating 2D vector data and a DTM, we presented an approach for the adaptation of 2D GIS road objects to airborne laser scanning (ALS) data using active contours (snakes) in (Göpfert et al., 2011). In this paper the algorithm is modified for the integration of stereo images as an alternative data source for area-wide heig...

By: I. Hijazi; D. Maes; M. Rezoug; R. El Meouche

Description: Institut de Recherche en Constructibilité-ESTP,Université Paris-Est, Cachan, France. With modern 3D laser scanners we can acquire a large amount of 3D data in only a few minutes. This technology results in a growing number of applications ranging from the digitalization of historical artifacts to facial authentication. The modeling process demands a lot of time and work (Tim Volodine, 2007). In comparison with the other two stages, the acquisition and the ...

By: S. K. Ghosh; S. Bhattacharjee

Description: School of Information Technology, Indian Institute of Technology Kharagpur, West Bengal-721302, India. Spatio-temporal land-use/ land-cover (LULC) change modeling is important to forecast the future LULC distribution, which may facilitate natural resource management, urban planning, etc. The spatio-temporal change in LULC trend often exhibits non-linear behavior, due to various dynamic factors, such as, human intervention (e.g., urbani...

By: P. Polewski; M. Heurich; U. Stilla; P. Krzystek; W. Yao

Description: Dept. of Geoinformatics, Munich University of Applied Sciences, 80333 Munich, Germany. Standing dead trees, known as snags, are an essential factor in maintaining biodiversity in forest ecosystems. Combined with their role as carbon sinks, this makes for a compelling reason to study their spatial distribution. This paper presents an integrated method to detect and delineate individual dead tree crowns from color infrared aerial imagery. Our approach consis...

Description: Centre for Integrated Petroleum Research (UniCIPR), Postboks 7810, 5020 Bergen, Norway. Texture mapping is a common method for combining surface geometry with image data, with the resulting photorealistic 3D models being suitable not only for visualization purposes but also for interpretation and spatiameasurement, in many application fields, such as cultural heritage and the earth sciences. When acquiring images for creation of photorealistic models, it is ...
