Rectifying the Planet

Planet Labs operates the largest constellation of earth observing satellites of any geospatial data provider. Each satellite is designed to continuously capture around one scene per second. With clouds, seasons, and a possible pointing error of up to 100 km, the Rectification Team is charged with aligning every pixel to its ground location. From experimental beginnings using GDALSimpleSURF, Planet's pipeline now includes FLANN, OpenCV, GDAL, GRASS, PROJ.4, and OSSIM. The Landsat 8 archive and Open Street Map database are automatically referenced to quickly provide robust, year-round, tie points.

Seth Price has been working at Planet for almost three years and has played a major role in the development of its image pipeline. He will discuss how each of these technologies play a role in image rectification.
