In this episode, Dr. Austin Madson interviews Chris Crosby, the co-principal investigator and director of operations and strategy for the OpenTopography project. OpenTopography facilitates efficient access to topographic data, tools, and resources to advance our understanding of the Earth's surface, vegetation, and the built environment. Funded by the National Science Foundation, it's arguably the most comprehensive source of topographic data on the internet. During our session, we review the different resources available at OpenTopography.org (and who can/can't access them) as well as the varied landscape of modern topographic data access and management.
