METHODS FOR ASSESSING ACCURACY IN DIGITAL GEODETIC MEASUREMENTS Akbaraliyeva Zamira Gulistan state university 32-25 group 1st year student https://doi.org/10.5281/zenodo.18231190 Abstract: The increasing reliance on digital geodetic measurements has fundamentally transformed modern surveying, mapping, and spatial data management practices. Advances in Global Navigation Satellite Systems (GNSS), Geographic Information Systems (GIS), and remote sensing technologies have enabled the rapid acquisition and processing of geospatial data with unprecedented efficiency. Nevertheless, the accuracy of digital geodetic measurements remains a critical factor influencing the reliability of engineering surveys, land administration systems, infrastructure development, and territorial planning. Even minor positional errors in digital datasets can propagate through spatial analyses, leading to inaccurate decision-making and inefficient resource management. This study provides a detailed examination of contemporary methods used to assess accuracy in digital geodetic measurements. The research emphasizes horizontal positional accuracy evaluation through the integration of GNSS-derived ground control points, digital topographic maps, satellite imagery, and geospatial databases. Widely accepted statistical indicators—including Root Mean Square Error (RMSE), Circular Error at 90% confidence (CE90), and Linear Error Probability (LEP)—are applied to quantify positional deviations and measurement uncertainty. The methodological framework ensures reproducibility and compliance with international cartographic and geodetic accuracy standards.
