Through their dedication to excellence and innovation, MandalaGIS continues to be a trusted partner for organizations seeking to navigate the complexities of the urban and regional built environment.


Hester Badenhorst

Hester forged her own path to success. Rather than following the traditional route into Town Planning after graduating from the University of Pretoria, she ventured into the realm of Spatial Analysis. It was here that she found her calling, immersing herself in the dynamic world of Geographic Information Systems (GIS). This environment not only engaged her analytical prowess but also sparked her creativity, appealing to both the logical left and imaginative right hemispheres of her brain

Willem Badenhorst

Willem found his way into the world of GIS somewhat unexpectedly while working as an urban and regional planner, focusing on land use and transport research at the CSIR. Following a decade of dedicated service in the research arena, he took the bold step of establishing MandalaGIS. Despite his transition, his passion for planning remained steadfast, and he continues to approach geo-design with an integrated, multi-sectoral perspective.

At his core, Willem remains a planner, always striving to weave narratives through the medium of maps. He possesses a genuine appreciation for a well-crafted map that not only conveys spatial information but also tells a compelling story.
