NansenCloud – framework for synergistic remote sensing in the Nansen Group Anton Korosov, Morten W. Hansen Nansen Environmental and Remote Sensing Center Scientific Council Meeting at the Nansen Center, 28 Nov 2014
Challenges with remote sensing data usage 1. «Complex data» challenge: Complicate to open and process a dataset 2. «Big data» challenge: Expensive to download, store and process many dataset 3. «Heterogeneous data»: Difficult to find a relevant dataset Scientific Council Meeting at the Nansen Center, 28 Nov 2014
Challenges with remote sensing data usage 1. «Complex data» challenge: Complicate to open and process a dataset 2. «Big data» challenge: Expensive to download, store and process many dataset 3. «Heterogeneous data»: Difficult to find a relevant dataset × 5 Scientific Council Meeting at the Nansen Center, 28 Nov 2014
Challenge #1 How to open and process a dataset ? Scientist friendly Python toolbox for processing 2D satellite earth observation data. The main goal is to facilitate: easy development and testing of scientific algorithms, easy analysis of geospatial data, and efficient operational processing.
