Orthorectification is main and specific photogrammetric task. Digital technologies allow generation of precise orthoimages, whic h are obtaining the pixel accuracy. The realization of this process requires usage of precise and adequate object model that is generated by usage of different data sources. They include irregular set of points created by survey measurements, digitized cartographic data, raster DEM obtained from stereo pairs, or from points’ cloud gathered by laser scanning. The main steps of orthorect...

The present study has been carried out with the use of Remote Sensing techniques in combination with Geographical Information Systems/GIS for monitoring and protection of the environment, in the surroundings of mining areas, as well as for developing new techniques for searching for new Mn-ore deposits, in Drama area, Northern Greece. Various digital processing techniques were applied on LANDSAT-TM imagery. These techniques included differe nt methodologies, such as the “Principal Component Analysis” (PCA), вЂ...

A various range of remote sensors are currently available to help to explore a landscape and other natural components. The mainly part of this field is based on a small format aerial photographs (SFAP) taken from a small aircraft. The scienti fic benefit arises from the combination of knowledge achieved by conventional field work and the visual information gleaned from SFAP. In monitoring studies, temporal changes of forms and patterns give additional clues. The coupling of field data and interpretation of SFAP...

Being located in mountain region, Rawa Danau Nature Reserve is the only one wetland area in the mountain region in Indonesis which formed very important component of its biophysical and physical environment. With the decreasing control of the local government and private agencies over the years, and rapid urban sprawl of the city, many of the water bodies have been totally lost. This has been converted to wet rice field cultivation and also expansion of illegal logging. One of our greatest environmental challenges...

Recent advances in remote sensing have changed conventional ways of collecting and processing elevation data. Especially Light Detection and Ranging (LiDAR) has become one of the leading technologies for rapid acquisition of elevation data. In this paper we present a system for digital elevation model (DEM) construction from LiDAR data. First, we present a visualization technique that allows efficient representation for LiDAR data processing. This makes the data segmentation, which is the key step in DEM generatio...

The opportunities for automation of the procedures for creating analytic photogrametric models, processing data from digital mapping and image processing are described. Examples for achieved results in the development of software for the specialized photogrammetric activities and for operating with the programme package < Photo > are given.

The approach for formal description of topological description of images is suggested. It is based on the grammar approach for the definition the different types of graphic images. The procedure for verification of defined image is developed. It is based on the conformity checks. The procedures for creation of such description from binary maps and grey level monochrome or multiband images are compared. The procedures for matching of identical points in images are introduced. Such approach is suitable for georefere...

The main goal of 2D and 3D object visualization is to present measured data in other way than in forms of text records and tables. FOTOM system is a general purpose platform for technical and medical image analysis. The primary target is to measure specified objects of interest. This paper covers the general description of the system and its main functions. We will briefly describe newly implemented modules for statistical evaluation, 3D modeling and 2D animation.

SД±r\ccalД± Medrese(Madrasa- moslem theological school), which is one of the most important medreses of Konya and Anatolia is in Konya Province, Meram District, GazialemЕџah Quarter.SД±r\ccalД± Medrese, that is among the medreses having an open courtyard, two liwans and two floors, has been had constructed by Bedreddin Muslih in the Period of GД±yaseddin Keyh\"usrev the 2nd. In the front parts of the building cut stone is used, while in other parts rubble stone is used. It has been used as medrese until 1924 with ...

The data obtained from Constant GBS (SGBS) networks which are established generally for the aim of geodesic, geodynamic and navigation studies also contribute to the meteorological studies. In this study, hourly temperature and pressure values measured by present meteorological sensors in SGPS stations as well as water vapor values (PWV) that can be converted into rain by taking the advantage of GPS observations will be calculated for Middle Anatolian Region. The values of GPS\_IPWV obtained as a result of calcula...

This paper deals with the topic of image calibration and transformation inside the photogrammetric system FOTOM 2008. The calibration module is used for approximate determination of outer camera parameters (position and rotation) with respect to captured objects. An additional transformation is based on similarity of homocentric circles and is accomplished in two steps, which will be described. Variables, obtained from the calibration are used for corrective projection enabling easier measurement of observed objec...
