“Calculations that used to take us a week are now done in minutes. That saves us a huge amount of time and money.”
Our story
From Zonnekaart to DZHK
MapGear B.V. was founded in 2013 by Wouter Goedhart and Egbert Griffioen with one clear mission: to make spatial data accessible to everyone. Our first product was Zonnekaart – a revolutionary tool that allowed citizens to easily calculate their roof’s solar potential.
What started as a consumer tool for solar energy quickly evolved into professional solutions. In 2015 we delivered ‘Zon zoekt Drenthe’, a project that mapped solar potential for all municipalities in the province of Drenthe. This established our reputation in the sustainable energy sector.
From 2018 we developed Zonnekaart Pro for professionals, and in 2024 we launched DZHK, our platform for climate adaptation, energy transition and citizen participation. Today we serve over 300 organisations across Europe.
