Basic-20: Hands-on training: Data preprocessing
Channel: HYPERedu
Date: 24/11/2021

The availability of hyperspectral data is still rather limited. Most data portals provide data in different processing levels including preprocessed ready-to-use Level 2 reflectance data. If preprocessing is not yet done or if you are not satisfied with the data quality of the preprocessed data, you may do the correction steps yourself. This video explains some aspects to consider on data selection and preprocessing.

**** FREE ONLINE COURSE ****

‘Beyond the Visible – Introduction to Hyperspectral Remote Sensing‘ is the first Massive Open Online Course (MOOC) on Hyperspectral Remote Sensing presented by HYPERedu and EO-College 

OPEN FROM 24 NOVEMBER 2021, 08:00 am GMT 

Register now: https://eo-college.org/courses/beyond-the-visible/

The course teaches the principles of imaging spectroscopy, sensor technologies and data acquisition techniques, hyperspectral data processing approaches and data sources and provides expert-guided hands-on training. 

The course was developed by GFZ Potsdam as part of the HYPERedu initiative with support from experts at various partner institutions. The development was funded within the EnMAP science program under the German Space Agency at DLR with resources from the German Federal Ministry of Economic Affairs and Energy.
