Deep Learning Applications for Space Imagery: Massive data to Intelligent Insights

NASA Earth Exchange (NEX) is a collaborative supercomputing facility housed in the NASA Ames High-end Computing Facility. Some of the key projects inside of NEX use computational methods, physical models and new analytical techniques to derive insights from massive data generated from a suite of satellite-derived imagery products. These datasets are geared towards mission-centric requirements, however, they are widely used by the scientific research community, stakeholders and commercial companies for a number of applications. We at NEX have invested on new hardware technologies and state-of-art machine learning models to classify and segment land cover objects from very high resolution satellite and airborne imagery and scaled it at continental scales by processing almost a quarter million image scenes every year to derive features that are critical for decision making for a number of government agencies. Here we will showcase some of the work that is being currently performed inside of NEX on the application of deep learning algorithms for land cover classification, crop segmentation, and climate downscaling.
