AB  - The paper analyzes the approximation of the ellipsoid by the sphere. Earth is a space body with a mathematically irregular shape, so idealized smooth surfaces are used for calculations. The first is the geoid, a smooth, equipotential surface that best approximates mean sea level. However, the geoid does not have an analytical form and is unsuitable for many applications, so an ellipsoid is used for approximation. In applications where high accuracy is not required (e.g., with small scale maps), the ellipsoid is approximated by a sphere. The radius of the sphere can be calculated in three ways: according to the equivalent volume criterion, according to the equivalent surface criterion, or as the mean value of the three semi-axes of the ellipsoid. All three methods of approximation were tested by calculating the length of the geodetic line on the ellipsoid, the orthodrome on the spheres and then the error. Also, the influence of latitude on the error value was tested. For three different values of geographic latitude, the lengths of geodetic lines up to one hundred points were calculated (using the Bessel method for solving the second main geodetic task on the ellipsoid), as well as the lengths of the orthodromes on the spheres, with the radii of the spheres determined in the three mentioned ways. The obtained results were then analyzed and discussed.

AB  - This paper presents GIS/3D solutions and their application in agriculture. Further, the possibilities of obtaining information important for planning the development of viticulture, fruit growing and farming are analysed and presented. Until now, maps have been most commonly used as models for terrain analysis. The main weaknesses of the maps are content freezing and difficult 3D analysis. With the advent of geoinformation technologies, the way of processing is changing and the concept of GIS/3D data modelling is being emphasized. The aim of this paper are new solutions that provide an efficient opportunity in field analysis and resource management in agriculture. An algorithm has been designed where, based on the given criteria (terrain slope, aspekt, vegetation index, altitude), representations of potential areas for growing certain crops are obtained. The results show numerous possibilities of GIS methodology for agricultural crop management, in this specific case of viticulture, arable farming and fruit growing. Also, the results in the form of geostatistical maps provide a more precise insight and serve as a basis for better decision-making in agriculture. The area of interest includes the Srem district, which is located in the northern part of the Republic of Serbia. This district is a resource of great importance for the further development of agriculture, of which viticulture and fruit growing are of special importance. For planning the development of agriculture in an area, it is necessary to have information related to both the assessment of land suitability and land valuation for certain agricultural species in order to be able to assign the optimal purpose.

AB  - This paper deals with the problem of Bessel procedures and processes in solving the main geodetic problems on an ellipsoid. There are a number of methods for solving the main geodetic tasks on the Earth's ellipsoid. They can be grouped into three categories, ie models for: short distances (up to 200 km), medium distances (200 to 1000 km) and long distances (over 1000 km). The aim of this paper is the application of the methodology for solving the main geodetic tasks for all distances on the eelipsoid, ie the application of one universal method. Since this method is iterative, the modern way of its implementation is a significant relief compared to its application in the past when there were no software designs and automated procedures. From the obtained results and length values, numerous analysis and conclusions can be derived, ie, process monitoring and error growth trend with increasing distance.

AB  - The paper discusses the concept of construction and monitoring of
capacity changes - the volume of the "Garajevac-Istok" excavation
(mine), located in the cadastral municipality of Novi Bečej. Namely, in
the earlier period, the physical surface of the Earth and geospace in
general were shown two-dimensionally (2D), in a plane, by some of
the cartographic methods (contour lines, points heights, hypsometry)
or three-dimensionally (3D), by modeling of reliefs and relief cards.
The cartographic principles of terrain making and visualizing on relief
mapping models allow the creation of 3D views, but not enough
quality and engineering precise 3D terrain models. In addition, there
is a possibility of quantitative and qualitative assessment of the
terrain on the mentioned models not to be accurate enough.
With new technologies, the 3D geospatial display mode changes, and
the concept of digital terrain modeling (DTM) is being applied. The
main goal of the work is to create 3D models and to give an analysis of
