The FOSS4GE 2024 conference logo was inspired by the conference venue, the city of Tartu. Therefore, one can notice different elements that are significant to the city.

• First of them is Struve's Geodetic Arc created by Friedrich Georg Wilhelm von Struve who was an astronomer at the University of Tartu in the 19th century. The arc, which is also on the list of UNESCO World Heritage, was the first accurate measurement of a long segment of a meridian, which helped to establish the exact size and shape of the planet. 34 of the original measuring points are known to exist, three of those are located in Estonia. In Tartu, the part belonging to the Struve meridian arc is the Tartu observatory which also indicates the longitude coordinate on the logo.

• The second important element is the ribbon interwoven between the letters of TARTU representing the river flowing through the city - Emajõgi. The river is a symbol of the city and plays a significant role in the lives of the local people. Locals enjoy spending time both on the shores and on the river.

• The third element is the OSGeo ribbon which blends into the letter A in Tartu. It is traditionally part of every FOSS4G conference logo symbolising the flow of ideas and innovation, and sharing within the Open Source geospatial community.

• The fourth element is the general triangular shape of the logo, representing a play button with a meaning of “Let’s get started!”

Author of the logo: University of Tartu Associate Professor in Cartography, Raivo Aunap.
