Abstract
<jats:p>The article substantiates the methodological principles for pre-design analysis of industrial territories, using the example of a seed processing plant covering 4.92 hectares. Attention is paid to the formation of an accurate spatial framework for architectural and engineering design through the application of RTK technology based on the GNSS reference station network System.NET. The research highlights the importance of high-precision geodetic support during the initial stages of industrial facility reconstruction and modernization, where reliable spatial data underpin effective planning and engineering decision-making. The study investigates the challenges of obtaining metric data under dense industrial development, where signal shielding, multipath effects, and limited satellite visibility significantly reduce the efficiency of conventional satellite measurements. To improve the reliability and accuracy of spatial positioning, an integrated approach combining GNSS observations with electronic total station surveying was implemented. A comparative analysis of the applied measurement methods was conducted, enabling the determination of optimal surveying conditions and the minimization of positioning errors when creating source graphic materials and digital cartographic datasets. A separate emphasis is placed on the use of computer graphics tools and GIS-based modeling methods to process and interpret the results obtained. Based on field measurements, a digital terrain model was created in QGIS using triangulation techniques. Through geovisualization tools, including slope maps and hillshade models, a comprehensive analysis of surface morphology was performed. The results obtained provide a reliable basis for vertical planning, drainage assessment, functional zoning, and the optimization of industrial infrastructure placement. The scientific novelty of the research lies in optimizing pre-design analysis methods for complex industrial territories by integrating precision geodetic measurements into a unified digital graphic model of the object. The practical significance of the study lies in improving the quality of architectural and planning decisions, reducing reconstruction risks, and increasing the level of automation in preparing project documentation. Keywords: pre-design analysis, architectural design, digital terrain model, computer graphics, GNSS, RTK, QGIS, industrial territories.</jats:p>
