Weekend Reading: RoboSat, the State of Security, and the Equal Earth Map
This excellent guide shows how to combine take imagery from OpenAerialMap and buildings from OpenStreetMap, and combine to train a model for automated feature extraction. It uses an open source tool from Mapbox called RoboSat combined to compare a GeoTIFF from OAM with a PBF extracts from OSM. Very cool to have a generalized tool for doing this with open data.
An excellent roundup (with tons of ancillary linked sources) on the state of various parts of computer security, from programming, to browsers, to social engineering.
