In this episode we revisit the talk that won the SplashMaps best speaker prize at the October 2020 Geomob. Ed interviews long-time geomobster Laurence Penney, who presented about the world's oldest known geospatial database: Ptolemy's Geography. A fascinating look back at how it all started.

The Geomob podcast is hosted by Ed Freyfogle, co-founder of OpenCage, and Steven Feldman, of KnowWhere Consulting.

Every week we discuss themes from the geo industry, interview Geomob speakers, and provide regular updates about our own projects.
