By: H. Müller; S. Hornung; S. Boos

Description: Mainz University of Applied Sciences, Institute for Spatial Information and Surveying Technology (i3mainz), Lucy-Hillebrand-Str. 2, D-55128 Mainz, Germany. Most archaeological predictive models lack significance because fuzziness of data and uncertainty in knowledge about human behaviour and natural processes are hardly ever considered. One possibility to cope with such uncertainties is utilization of probability based approaches like Bayes Theorem or Demp...

By: M. Pahl; J. Ostermann; C. Becker

Description: Leibniz Universit¨at Hannover Institut f¨ur Informationsverarbeitung Appelstr. 9a, 30167 Hannover, Germany. Data in Geo Information Systems (GIS) is used for map services and various applications. Thus, quality assessment on a regular basis is required to keep the data up-to-date. In this paper we focus on one key reasons for updates: incorrect object borders. State of the art systems semi-automatically analyse up-to-date satellite image data to narrow dow...

By: G. M. Foody; A. Comber; D. Rocchini; M. Neteler; Q. Groom; A. M. Barbosa; C. X. Garzon-lopez; M. Marcantonio; C. Da Costa Fonte

Description: Department of Biodiversity and Molecular Ecology, Research and Innovation Centre, Fondazione Edmund Mach, Via E. Mach 1, 38010 S Michele allAdige, TN, Italy. Species distribution models represent an important approach to map the spread of plant and animal species over space (and time). As all the statistical modelling techniques related to data from the field, they are prone to uncertainty. In this study we explicitly dealt with uncertainty deriving from f...

By: P. L. N. Raju; R. K. Singh; Y. V. N. Krishnamurthy; M. Kumar

Description: Indian Institute of Remote Sensing , Dehradun, India. High Resolution satellite Imagery is an important source for road network extraction for urban road database creation, refinement and updating. However due to complexity of the scene in an urban environment, automated extraction of such features using various line and edge detection algorithms is limited. In this paper we present an integrated approach to extract road network from high resolution space...

By: A. Bienert; D. Schneider

Description: Technische Universität Dresden, Institute of Photogrammetry and Remote Sensing, 01062 Dresden, Germany. To make a tree-wise analysis inside a forest stand, the trees have to be identified. An interactive segmentation is often labourintensive and time-consuming. Therefore, an automatic detection process will aspired using a range image. This paper presents a method for the segmentation of range images extracted from terrestrial laser scanner point clouds of...

An Accurate Heading Solution Using Mems-based Gyroscope and Magnet...

By: M. El-diasty

Description: Hydrographic Surveying Department, Faculty of Maritime Studies, King Abdulaziz University, Saudi Arabia. An accurate heading solution is required for many applications and it can be achieved by high grade (high cost) gyroscopes (gyros) which may not be suitable for such applications. Micro-Electro Mechanical Systems-based (MEMS) is an emerging technology, which has the potential of providing heading solution using a low cost MEMS-based gyro. However, MEMS-...

Description: Department of Geodesy, Cartography and Cadastre, Faculty of Geography, National University of Uzbekistan, Tashkent, Uzbekistan. Automated generalization, rooted from conventional cartography, has become an increasing concern in both geographic information system (GIS) and mapping fields. All geographic phenomenon and the processes are bound to the scale, as it is impossible for human being to observe the Earth and the processes in it without decreasing its...

Description: School of Remote Sensing and Information Engineering, Wuhan University, No.129, LuoYu Road, WuHan, China. While a lot of approaches have been reported for change detection using high resolution images, few approaches which are used for different scale images have been developed. This paper proposes a change detection approach which can be used to detect the change in images with different scales. In this study, image objects have been extracted from images...

By: M. De Kramer; S. Senecal; M. Flores Gutirrez; C. M. Coughenour; D. Fritsch; V. M. Lopez-menchero Bendicho; M. Ioannides; M. L. Vincent

Description: Institute for Photogrammetry, University of Stuttgart, Geschwister-Scholl-Str. 24D, 70174 Stuttgart, Germany. At present, where 3D modeling and visualisation in cultural heritage are concerned, an object’s documentation lacks its interconnected memory provided by multidisciplinary examination and linked data. As the layers of paint, wood, and brick recount a structure’s physical properties, the intangible, such as the forms of worship through song, dance, ...

Roof Reconstruction from Point Clouds Using Importance Sampling : ...

By: H. Mayer; M. Drauschke; W. Nguatem

Description: University of Bundeswehr, Munich, Institute of Applied Computer Science, Chair for Visual Computing, Neubiberg, Germany. We propose a novel fully automatic technique for roof fitting in 3D point clouds based on sequential importance sampling (SIS). Our approach makes no assumption of the nature (sparse, dense) or origin (LIDAR, image matching) of the point clouds and further distinguishes, automatically, between different basic roof types based on model se...
