An Automated Process of Creating 3D City Model for Monitoring Urban Infrastructures

This paper describes the process of designing models and tools for an automated way of creating 3D city model based on a raw point cloud.Also, making and forming 3D models of buildings. Models and tools for creating tools made in the model builder application within the ArcGIS Pro software. An unclassified point cloud obtained by the LiDAR system was used for the model input data. The point cloud, collected by the airborne laser scanning system (ALS), is classified into several classes: ground, high and low noise, and buildings. Based on the created DEMs, points classified as buildings and formed prints of buildings, realistic 3D city models were created. Created 3D models of cities can be used as a basis for monitoring the infrastructure of settlements and other analyzes that are important for further development and architecture of cities

GIS / 3D solutions in the function of management improvement in agriculture

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
