Learning to Map Nearly Anything

no code implementations16 Sep 2019 Tawfiq Salem, Connor Greenwell, Hunter Blanton, Nathan Jacobs

Looking at the world from above, it is possible to estimate many properties of a given location, including the type of land cover and the expected land use.

Learning Geo-Temporal Image Features

no code implementations16 Sep 2019 Menghua Zhai, Tawfiq Salem, Connor Greenwell, Scott Workman, Robert Pless, Nathan Jacobs

We propose to implicitly learn to extract geo-temporal image features, which are mid-level features related to when and where an image was captured, by explicitly optimizing for a set of location and time estimation tasks.
