The article presents a methodology for automated detection of anomalous geospatial zones, implemented as a plugin for the QGIS geographic information system. The developed tool enhances the efficiency of spatial data analysis and enables rapid identification of territories with potential changes, which is essential for monitoring natural and anthropogenic processes. The proposed approach is based on the integration of threshold and statistical analysis of satellite imagery within the QGIS environment. The plugin provides interactive adjustment of image processing parameters and automatically detects geodynamic anomalies, which are subsequently vectorized and made available to the user for further interpretation. Testing of the plugin on InSAR-type satellite data confirmed its effectiveness in identifying zones of vertical ground displacement. The obtained results demonstrate the practical applicability of the tool for geodynamic monitoring and highlight promising directions for future development, particularly the implementation of separate processing of positive and negative displacements to improve the accuracy of anomaly identification.
