Obviously, each town has a name. But in a system of grid-based urban/rural classifications, towns are defined as clusters of 1 km² grid cells. These grid-based towns do not have any a-priori name. Still, providing names to these units can be useful to facilitate referencing them. Hence, the challenge is to provide (unique) names for more than 9000 towns throughout Europe.
A short note explains the process followed to allocate names to grid-based towns. An interactive map
viewer allows exploring and evaluating the naming of the towns and allows users to provide feedback and suggestions for improvement.
