The platform for sustainability data

About Duurzaamheidskaart

Duurzaamheidskaart is developed by MapGear B.V. Our products: Duurzaamheidskaart (data platform for climate adaptation and energy transition), Zonnekaart (solar potential for residents and professionals), GeoApps (mapping platform for visualisations and geodata), Duurzaamheidstafel (interactive touch tables for presentations and collaboration) and PraatMee (participation tool for citizen engagement). We connect with data and advisory partners such as TAUW and Syntraal. Together we offer municipalities and provinces one platform for climate adaptation, energy transition and sustainability data.

Our story

From Zonnekaart to Duurzaamheidskaart

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 Duurzaamheidskaart, our platform for climate adaptation, energy transition and citizen participation. Today we serve over 300 organisations across Europe.
