The specific aim of the European project named "Cultural Heritage Through Time" (CHT2) and reported in this paper is to fully integrate the fourth dimension (4D) into Cultural Heritage studies for analysing structures and landscapes over time. Krakow – the Fortress City (Poland) is the one of four case studies of the CHT2, which are used for the time varying reconstruction, analysis, visualization,...
When it comes to housing pricing, particularly when housing estates are concerned, determining price differences based on varying features is an important aspect. In practice, floor premiums are calculated via a selection of methods and reflected in prices. In this study, parameters thought to influence housing prices have been weighted to find out the prices of all available apartments in a housing...
3D point clouds are essential sources in acquiring information for many applications such as cultural heritage protection/restoration, building information modeling and management or architectonic documentation. The quality of TLS point clouds is very important in such applications because of its completeness, and structural information capacity. With a growing demand on photogrammetric products accuracy,...
Wave-length dependant imaging errors of the optical components and different characteristics in colour channels yield various geometric errors of the RGB image. Chromatic aberration has a very large direct impact on the quality of a digital image correlation and indirect on the geometry of the image. This is particularly important when recording black and white images on the RGB array. It is also...
The paper presents the results of multi-view imagery 3D reconstruction of the close range building using the geodetic and photogrammetric networks and image based point clouds. DSLR camera was used to acquire the block of 28 terrestrial multiple convergent photos. To create the benchmark data set, the bundle block adjustment with camera self calibration in the Pictran software package was performed...
The RTK GNSS method is commonly used in the 3D machine control systems. The RTK GNSS solution corrected by a laser level system (millimetre GNSS (mmGPS)) has been designed to improve the vertical accuracy of RTK GNSS positioning. The purpose of this study was to verify mmGPS technology in different situations. Test measurements in two test areas were carried out to evaluate the accuracy, working radius,...
Laser scanning technology is a spatial information gathering technique which is commonly used all over the world. Systems where the red-light beam are used, are divided into: terrestrial, mobile and airborne scanning systems. The main differences between those are the accuracy, the data acquisition solution (f. e. in ALS and MLS besides of the laser scanner, the inertial navigation system is required)...
This study investigates the influence of basic planning conditions applicable to land zoned for residential development (single-family detached homes and multiple occupancy homes), set forth in zoning plans, on the value of property. The influence of the following factors was evaluated: the availability of zoning decisions, width of the front elevation, development density, maximum developed area...
LitPOS (Lithuanian Positioning System), the network of continuously operating GNSS stations, became operational in July 2007. It provides data both for real-time and post-processing applications. LitPOS stations cover the whole territory of Lithuania. Total number of LitPOS GNSS stations during is 30 stations. Also LitPOS network includes 3 ASG-EUPOS (Poland) and 6 LATPOS (Latvia) stations.LitPOS...
The article analyzes private land sales in administrative territories of Lithuania during the period of 2015-2016. The aim of the research is to determine the intensity of land sales and the reasons affecting land market prices that are not the same in the individual municipalities. The regression analysis has shown that the size of towns located in the municipality, and the portion of land owned...
This article presents the analysis of state forest block network geodetical measurement accuracy. Geodetic measurement network is compared to the pre-formed block network, which is registered in the State Forestry cadaster.Preliminarily shaped forest block network lines are geodetically measured with analogous points X and Y, and then the coordinates were adjusted to blocks at intersection points...
Technological advances and an increased demand for reconnaissance images acquired in different spectral ranges of the electromagnetic spectrum for Imagery Intelligence have contributed to the construction of a reconnaissance pod system DB-110. The main aim of this article was a comparison of pictures acquired in the visible, near-infrared and mid-infrared ranges. The analyses was carried out by comparing...
In this study we present analysis of the impact of Galileo observations on the ZTD and tropospheric gradients estimation. The tropospheric parameters were obtained in various scenarios, which differ from each other only in used satellite systems: Galileo-only, GPS-only, GPS/Galileo, GPS/GLONASS and GPS/GLONASS/Galileo. Then, comparative analysis between Galileo-only solution and the other ones, was...
In road construction, construction machines are used for levelling and adjusting the earth's surface. These modern construction machines use a 3D GNSS levelling system to achieve the projected shape and elevation of terrain with the required accuracy within permitted setting-out deviations according to the project. In the area of interest were realized geodetic check measurements. The aim was to objectively...
