Raster Frames, spatial imagery in apache spark

Raster Frames - Making imagery a first class citizen of apache spark

by Daniel ODonohue 12 min read

Commercial satellite providers produce somewhere between 100 and 200 terabytes of imagery a day ̶ a monstrous amount of information. Sentinel 2 has five years of daily refresh data. We have 40+ years of Landsat data. It’s a massive amount, particularly in the temporal dimension, where you can do longitudinal studies. Apache Spark and Raster Frames might just be the tools we need to handle this much data.

Robotics, remote sensing and facilities management

by Daniel ODonohue 9 min read

The Mars Rover Project.  Autonomous robots monitoring substations.  How is this all relevant to the geospatial community? Scott Nowicki is happy to clarify. He explains the technology that enables robots to integrate detailed maps, orientate, and move around their environments as they go on their daily business and build detailed change detection maps for substations and facilities management. But the question is, can they and do they truly add value to operations where human presence is difficult or unnecessary?
