AB  - Transport management is one of the most important logistical tasks, and the designing the optimal transport routes plays a major role in that process. Vehicle routing is primarily of interest to companies that organize the transportation of goods to end users, with the aim of minimizing the total cost of the routes. Being a well-known NP-hard problem, the theoretical background of the vehicle routing problem has been researched for many years and it has been the basis for the development of a large number of commercial software. However, affordable software solutions are lacking. Difficult access to high quality and reliable spatial data related to the road network is also a limitation. This paper discusses the possibilities of applying open-source software for solving the VRP. Open spatial data from a collaborative project of the virtual community was used as the basis for modeling the road network graph. The experiment was carried out on data on vehicles and customers of a certain retail chain and refers to the territory of Serbia.

AB  - Airborne Laser Scanning (ALS) is one of the most popular and cost-effective approaches for collecting Digital Elevation Model (DEM) data. This especially applies to large areas, forested areas, areas with dense vegetation and urban environments. The ALS results in a vast amount of data in the form of point clouds. Successful use of such data requires applying semi-automatic and automatic approaches to classify points according to which objects or phenomena it represents. LAStools software package represents a set of highly efficient tools for processing ALS data. Through this study, the functionality of the LAStools software package for DEM generation has
been analyzed. The proposed procedure for generating DEM products from ALS point cloud with LAStools has been determined and presented. The study also focuses on the important parameters of each tool in the proposed DEM procedure, with a special focus on advantages and disadvantages, possibilities and limitations.

AB  - Land readjustment (LR) is increasingly applied as a tool of urban policy implementation in many countries of the world. In Serbia, LR is a new tool that is being introduced into the legal system and into planning practice, from which a significant contribution to the urban development of the country is expected. Countries have different models of LR, which are adjusted to the particular conditions specific for that society. This is to be expected, having in mind the specificity of each country. This paper presents the development of land readjustment models which are adjusted to Serbia, but could also be used in the countries of South-East Europe, considering that the predominant conditions are similar. The most important item in this process is defining the key elements which determine the nature of the model: the existence and appropriateness of the urban plan and the distribution of benefits from increased land value. The paper also presents a case study of LR implementation on the basis of defined models, after which an analysis of the outcomes is presented. It is concluded that by applying the LR models presented, numerous significant issues that occurred in the past can be solved.

AB  - Numerous semi- and fully-automatic algorithms have been developed for individual tree detection from airborne laser-scanning data, but different rates of falsely detected treetops also accompany their results. In this paper, we proposed an approach that includes a machine learning based refinement step to reduce the number of falsely detected treetops. The approach involves the local maxima filtering and segmentation of the canopy height model to extract different segment level features used for the classification of treetop candidates. The study was conducted in a mixed temperate forest, predominantly deciduous, with a complex topography and an area size of 0.6 km × 4 km. The classification model’s training was performed by five machine learning approaches: Random Forest (RF), Extreme Gradient Boosting, Artificial Neural Network, the Support Vector
Machine, and Logistic Regression. The final classification model with optimal hyperparameters was adopted based on the best-performing classifier (RF). The overall accuracy (OA) and kappa coefficient (κ) obtained from the ten-fold cross validation for the training data were 90.4% and 0.808, respectively. The prediction of the test data resulted in an OA = 89.0% and a κ = 0.757. This indicates that the proposed method could be an adequate solution for the reduction of falsely detected treetops before tree crown segmentation, especially in deciduous forests.

AB  - The inventory of woody vegetation is of great importance for good forest management. Advancements of remote sensing techniques have provided excellent tools for such purposes, reducing the required amount of time and labor, yet with high accuracy and the information richness. Sentinel-2 is one of the relatively new satellite missions, whose 13 spectral bands and short revisit time proved to be very useful when it comes to forest monitoring. In this study, the novel spatio-temporal classification framework for mapping woody vegetation from Sentinel-2 multitemporal data has been proposed. The used framework is based on the probability random forest classification, where temporal information is explicitly defined in the model. Because of this, several predictions are made for each pixel of the study area, which allow for specific spatio-temporal aggregation to be performed. The proposed methodology has been successfully applied for mapping eight potential forest and shrubby vegetation types over the study area of Serbia. Several spatio-temporal aggregation approaches have been tested, divided into two main groups: pixel-based and neighborhood-based. The validation metrics show that determining the most common vegetation type classes in the neighborhood of 5 × 5 pixels provides the best results. The overall accuracy and kappa coefficient obtained from five-fold cross validation of the results are 82.97% and 0.75, respectively. The corresponding producer’s accuracies range from 36.74% to 97.99% and user’s accuracies range from 46.31% to 98.43%. The proposed methodology proved to be applicable for mapping woody vegetation in Serbia and shows a potential to be implemented in other areas as well. Further testing is necessary to confirm such assumptions.

AB  - ESA CCI SM products have provided remotely-sensed surface soil moisture (SSM) content with the best spatial and temporal coverage thus far, although its output spatial resolution of 25 km is too coarse for many regional and local applications. The downscaling methodology presented in this paper improves ESA CCI SM spatial resolution to 1 km using two-step approach. The first step is used as a data engineering tool and its output is used as an input for the Random forest model in the second step. In addition to improvements in terms of spatial resolution, the approach also considers the problem of data gaps. The filling of these gaps is the initial step of the procedure, which in the end produces a continuous product in both temporal and spatial domains. The methodology uses combined active and passive ESA CCI SM products in addition to in situ soil moisture observations and the set of auxiliary downscaling predictors. The research tested several variants of Random forest models to determine the best combination of ESA CCI SM products. The conclusion is that synergic use of all ESA CCI SM products together with the auxiliary datasets in the downscaling procedure provides better results than using just one type of ESA CCI SM product alone. The methodology was applied for obtaining SSM maps for the area of California, USA during 2016. The accuracy of tested models was validated using five-fold cross-validation against in situ data and the best variation of model achieved RMSE, R2 and MAE of 0.0518 m3/m3, 0.7312 and 0.0374 m3/m3, respectively. The methodology proved to be useful for generating high-resolution SSM products, although additional improvements are necessary.

AB  - One of the dimensions describing accessibility to health services is its spatial component. This paper presents the methodology of using GIS technologies for the analysis of existing locations of health institutions in Serbia. The methodology includes determining the coordinates of hospitals using the geotagging, on the basis of which isochrons are created with 10 minutes time interval. For that purpose, the road network and functionalities provided by HERE Maps and its APIs are used. This service is selected since it offers high quality and complete data related to the network of roads in the territory of interest. Taking demographic data into account, the goal is to examine the impact that the distribution of institutions has on the population, first of all as the percentage of the population living at a certain distance from the nearest institution. The obtained results can be significant for future development, as critical spots with poor accessibility can be identified. These locations are suitable for the construction of new health care facilities.
AB  - Jedna od dimenzija koje opisuju pristupačnost zdravstvenim uslugama jeste prostorna komponenta.

abstract = "One of the dimensions describing accessibility to health services is its spatial component. This paper presents the methodology of using GIS technologies for the analysis of existing locations of health institutions in Serbia. The methodology includes determining the coordinates of hospitals using the geotagging, on the basis of which isochrons are created with 10 minutes time interval. For that purpose, the road network and functionalities provided by HERE Maps and its APIs are used. This service is selected since it offers high quality and complete data related to the network of roads in the territory of interest. Taking demographic data into account, the goal is to examine the impact that the distribution of institutions has on the population, first of all as the percentage of the population living at a certain distance from the nearest institution. The obtained results can be significant for future development, as critical spots with poor accessibility can be identified. These locations are suitable for the construction of new health care facilities., Jedna od dimenzija koje opisuju pristupačnost zdravstvenim uslugama jeste prostorna komponenta.

AB  - The methodology for modeling the distribution of certain air pollutant for the city of Belgrade in winter 2015 is presented in the paper. Land Use Regression (LUR) was used for modeling and visualization of spatial distribution of air pollution concentration in the city. NO2 concentrations were sampled at 46 locations, and predictive variables were calculated based on the road category, traffic intensity, demographic data, altitude, household furnaces and land use. These variables were calculated using buffers of different sizes. Linear regressions between NO2 and predictive spatial variables were calculated. Afterwards, the most significant predictors were used for multivariate regression model. Quality of the final model was checked using measurement available at certain locations. The RMSE of 9.8 μg/m³ and the coefficient of determination (R2) of 0.6 were obtained. These results indicate that traffic has the largest impact on air pollution concentration especially near the major roads. Prediction should help in deciding which air protection measures are to be taken in order to preserve and improve the city environment. The lack of data that are collected by using quite a few sensor stations is still rather limiting for the successful monitoring of air pollution in the city of Belgrade.

AB  - This paper presents a universal model of weighted coordinate transformation, i.e. transformation considering the errors of coordinates in both coordinate systems. It is intrinsically one of the typical examples of 'error-in-variables' (EIV) models. The proposed method of LS theory application on weighted coordinate transformation does not impose any constraints on the form of functional relationship among stochastic variables. Since the basic idea is to generalise Gauss-Markov model (GMM) by introduction of so-called 'total residuals', the proposed procedure is named 'Generalised Gauss-Markov model'. Formulation of expressions for estimation of unknown transformation parameters is theoretically confirmed using the Gauss-Helmert model (GHM) and three different modifications of the GMM. The proposed procedure is in its essence a strict solution to total least-squares (unweighted) and weighted total least-squares problem in coordinate transformation. This thesis is experimentally confirmed by comparison of its results with those found in four characteristic examples from the literature.

AB  - High resolution (10 m and 20 m) optical imagery satellite Sentinel-2 brings a new perspective to Earth observation. Its frequent revisit time enables monitoring the Earth surface with high reliability. Since Sentinel-2 data is provided free of charge by the European Space Agency, its mass use for variety of purposes is expected. Quality evaluation of Sentinel-2 data is thus necessary. Quality analysis in this experiment is based on comparison of Sentinel-2 imagery with reference data (orthophoto). From the possible set of features to compare (point features, texture lines, objects, etc.) line segments were chosen because visual analysis suggested that scale differences matter least for these features. The experiment was thus designed to compare long line segments (e.g. airstrips, roads, etc.) in both datasets as the most representative entities. Edge detection was applied to both images and corresponding edges were manually selected. The statistical parameter which describes the geometrical relation between different images (and between datasets in general) covering the same area is calculated as the distance between corresponding curves in two datasets. The experiment was conducted for two different test sites, Austria and Serbia. From 21 lines with a total length of ca. 120 km the average offset of 6.031 m (0.60 pixel of Sentinel-2) was obtained for Austria, whereas for Serbia the average offset of 12.720 m (1.27 pixel of Sentinel-2) was obtained out of 10 lines with a total length of ca. 38 km.

The DCM is treated as the basis for establishment of the coordinate based cadastre (CBC) in Serbia. The research is focused on the following: the status of the state survey data especially regarding analogue cadastral maps and state geodetic reference network, production of DCM database, the introduction of a new spatial reference system, and legislation covering this field in Serbia. The existing geodetic/surveying network for cadastral/topographic survey and analogue cadastral maps are analysed in terms of their quality. The research also covers an analysis of present methods and procedures for DCM production using data obtained from various sources. Coordinate differences for DCM points and differences between areas of polygon features obtained using original survey data and those obtained by digitising scanned cadastral maps are analysed. The procedure of legislating information letters and resolutions on changes of areas within the DCM production procedure and the impact of the transition from the Gauss-Kruger to the UTM projection on areas for DCM polygon features are also analysed.

AB  - Paper deals with the specific LBS scenario – Fleet management (FM) and more specifically with systems for Automatic vehicle location (AVL). Well designed and implemented spatial data model for moving objects is one of the most significant elements of any AVL system. In practical applications the results of the latest scientific research are seldom applied, despite the fact that this area has been developing intensively for more than 20 years. The reasons for this are analysed in the paper. Short analysis of functionality of these systems is presented considering the impact of these functionalities on the implemented data model for moving objects and more specifically their impact on spatio-temporal component of the model. The paper especially reviews the possibility of using road networks as a basis for the representation of moving objects data models and a fact that these models are rarely used in practical applications. A solution overcoming this situation is proposed. The solution assumes transition from the system that is not based on road network to the system that is based on network. There are quite few research papers dealing with OSM data models. Therefore, a significant space in this paper is dedicated to the description of these models since OSM data can be valuable for this type of applications.

AB  - Significant innovations and improvements in the technologies for spatial data acquisition and management data
have emerged in the last few decades. Introduction of GPS and the technology of GIS and digital photogrammetry in
surveying practice are definitely the most important ones. In spite of this, during the last few decades there were no actual
projects of land consolidations in Serbia, so these advances in technology were not implemented within land consolidations
and benefits were not obvious and quantified. However, in the last few years interest in land consolidations in Serbia has
been intensified and a number of projects have been started and some were already finished using the latest technologies
mentioned above. The role and impact of these technologies on all the relevant activities within major phases of land
consolidation projects were analyzed and the resulting benefits were estimated and given in the paper. Improvements and
benefits were estimated using data from a real land consolidation project. The benefits were expressed in terms of savings in
time and costs and in terms of increased quality of the land consolidation results.

AB  - Algorithms and software for digital terrain modeling using TIN based surface model are presented in the paper. Processing of all types of terrain surface data are supported: mass points, local extrema, contours, breaklines, structure lines, fault lines, etc. TIN topology and Bézier triangular surface patches are used for terrain surface reconstruction. Special attention is dedicated to the problem of respecting all implicit information about terrain surface that are contained within the input data. This is especially important in cases when terrain surface has to be reconstructed by using mostly contour data, since there are a lot of additional information that are implicitly contained within the data of this type. The software also contains functions for efficient verification of collected terrain data and DTM. Special consideration is given to the numerical procedures and algorithms aiming at providing contours and other outputs of DTM analysis of cartographic quality as required by many surveyors and their clients. The results of experiments demonstrated that the quality of terrain surface reconstruction from contours and/or other data using developed procedures and software is better, or at least as good as the quality achieved by using procedures and methods implemented within standard GIS/DTM software.

AB  - Some limitation brought to us by cameras and imaging platforms sometimes can not be overcome as for the case of minimum airplane flight height used as platforms. In other case imaging of larger territories is often irrational, when it is performed from balloons or helicopters. So, there is an often need for combining different cameras and imaging platforms. New digital airborne cameras and non-metric high resolutions digital cameras expands our possibilities for combining this imaging source where we can get to optimal data source without disconcerting accuracy and unnecessary job build-up. In this paper the methodology of combining photogrammetric digital camera Z/I Imaging DMC and Canon EOS 5D will be presented as a source of data needed for photogrammetric product making of complex archaeological location with different photo resolutions.

AB  - Paper reviews achieved level of orthophoto production in Serbia, with estimates on further developments in the next few years. Users, sources of financing, application areas, state and private sector partnership, etc. are particularly analyzed. Role of orthophoto in a situation characterized by outdated official maps, especially for urban areas with a large number of new objects, and even whole new settlements which are not surveyed and mapped is evaluated. Digital orthophoto also plays key role in Serbia in all cases where large scaled GIS establishment is concerned. Paper also reviews gained experiences related to this matter. Although there is a generally unquestionable support to orthophoto in Serbia, there are still some issues that have to be dealt with. For example, when orthophoto utilization for cadastral purposes is considered, there is no answer to the question whether or not, and under which conditions, digital orthophoto could be used for the update of official cadastral maps at 1:1000 and 1:2500 scale. Some solutions to this dilemma are presented in paper. Some other related issues such as technical regulations for digital orthophoto production, copyright, establishment of the national orthophoto program, etc. are also reviewed in the paper.

AB  - Paper presents procedures and experiences on using low cost desktop scanner Epson Expression 1640XL for orthophoto production.Complete process of scanning, scanner calibration and removal of systematic distortions of scanned images caused by scanner is developed and tested on several large projects of orthophoto production. Special, user-friendly software is developed for these purposes. The software includes algorithm for scanner calibration and estimation of distortions based on statistical analysis by using collocation (linear prediction). It is not expected and required from user to have any idea on the structure and distribution of scanner errors. These will be determined by the statistical analysis. Therefore, the software usage is not limited to any particular scanner or the type and nature of image distortions it introduces. Batch processing of scanned images is also supported with options for saving images in various formats and using several resampling types. The results presented in paper shows that the procedure is very fast and reliable when geometric accuracy of scanning is concerned. The potentials of the developed software and procedure are high. Total costs for the software and the scanner are approximately tentimes lower than costs for the professional photogrammetric scanner. The geometric accuracy achieved is between 5 and 10μm, which is less than one pixel size in highest scanning resolution (1600 DPI). The aspects of the scanner usage at a high production rate are also analysed. Finally, recommendations for further improvements of the developed procedures are given.

AB  - This paper evaluates advantages of application of digital photogrammetry for the purposes of production of technical documentation for the objects under protection, comparing it with the classical photogrammetric procedures. Based on gained experiences, paper reviews procedures for the completely digital production of technical documentation. Process of making technical documentation is divided in two logical stages. First stage comprises of photogrammetric recording, necessary field measurements and production of archive documentation. Archive documentation is in completely digital form and it includes: geometrically rectified photogrammetric photos, data on control points, parameters of exterior orientation for all photos and digital orthophotos as a preliminary source of geometric information. Second stage involves the production of detailed documentation with data describing object geometry such as: floor plans, facades, sections, etc, by using suitable CAD tools. Considering that this constitutes the most complicated and the most expensive part of making technical documentation, this stage is done when needed. Proposed method will be illustrated in paper by using experiences gained on projects of making technical documentations for objects of historical and cultural heritage for the towns of Kragujevac (Serbia and Montenegro) and Banja Luka (Republic of Srpska).
