Tech Radars originated as a way for technology-driven organizations to assess and communicate emerging trends. ThoughtWorks popularized the concept in 2010 with their Technology Radar, a periodic report categorizing technologies into “Adopt”, “Trial”, “Assess”, and “Hold” to guide decision-making.
The format has since been adopted by other companies, including Zalando and Spotify, often customized for internal use.
I recently came across the Geospatial Tech Radar by Element 84. I recommend exploring this one, as it is well-executed from both a content and design/UI perspective.
PS: There is a Swiss variation of a geospatial tech radar called GIS Trends by SOGI (only available in German). However, it has a different focus and level of depth.
