Abstract: Rapid developments in remote sensing technology have brought significant opportunities by providing cutting- edge optical remote sensing data in a cost-effective manner. In particular, rich spatial details embedded in high-resolution remote sensing images provide great potential to understand our environment. In this tutorial, we will cover the basic characteristics of remote sensing images, and introduce open source software and deep learning libraries for geospatial data analysis. We will present the use of a convolutional neural network architecture to perform the tasks of object detection and segmentation with remote sensing images spanning very large geographical extents. We will also talk about the multi-GPU training that enables accelerated geospatial intelligence extraction.
