Currently, I am working as a Junior GIS Specialist at Geodienst. In addition to that, I am following a Master's in Real Estate Studies at the University of Groningen after completing my Bachelor's in Spatial Planning and Design. At Geodiest, I have worked on a variety of different projects - from a dashboard about women forced to quit around the world to calculating the changes in African borders. Mostly I focus on visualizations, one of which won the GIN Cartography prize in 2024.

Calculating changes in African borders in QGIS
Lilia Boyadzhieva

This presentation explores a GIS-based method for quantifying changes in regional borders across selected African countries by leveraging historical cartographic data we did at Geodienst. Using QGIS, particularly the georeferencing tool and the Model Designer, historical and current borders are systematically analyzed to support spatial research on territorial transformation.
