This slide collection focusses on quantification using regression analysis and RTMs. Following a short introduction about radiance regime of vegetation, we provide an overview about retrieval methods of vegetation bio-geophysical and biochemical traits from imaging spectroscopy data. Retrieval methods can be classified into the following four methodological categories: (1) parametric & (2) nonparametric regressions, (3) RTMs, and (4) hybrid methods. Further, emulation and quantification of uncertainties will be briefly discussed in this lecture.
Methods
Dimensionality reduction of imaging spectroscopy data
This unit provides an introduction to dimensionality reduction methods related to hyperspectral data or imaging spectroscopy. First, feature engineering methods using selected parametric and nonparametric regression methods are presented. Second, feature selection or extraction, using filter, wrapper and embedded methods will be discussed. Finally, some alternative methods are presented.

- Land Use / Land Cover
- EO Image classification
- Land Cover Classification Systems
- Accuracy Assessment
The material is valid for all fields of Earth observation, not only Radar remote sensing.
SAR Processing and Data Analysis
This presentation is part of a four-part series on the basics on Synthetic Aperture Radar.
Learning Objectives:
- Understand Sentinel Data
- Perform image preprocessing
- Analyze SAR imagery to classify land and water

Dr. Erika Podest is a scientist with the Carbon Cycle and Ecosystems Group at NASA’s Jet Propulsion Laboratory. Her research focuses on using Earth observing satellites, particularly microwave sensors, for characterizing and monitoring wetland ecosystems and seasonal freeze/thaw dynamics in the northern high latitudes as related to the global carbon and water cycles and climate change. She is working on the Soil Moisture Active Passive (SMAP) mission, a NASA Earth observing satellite that launched on Jan. 31 2015, which is improving our understanding of Earth’s water and carbon cycles and our ability to manage water resources.

SAR Handbook
The SAR Handbook: Comprehensive Methodologies for Forest Monitoring and Biomass Estimation is the culmination of a two-year collaboration between NASA SERVIR and SilvaCarbon. Five trainings, led by six SAR subject matter experts, were held at hubs throughout the SERVIR network. The topics of these trainings included SAR basics, SAR for forest change detection, forest height estimation, biomass estimation, mangrove monitoring, and sampling design. Each of these training topics are covered in a SAR Handbook chapter, which includes the theoretical basics and applied exercises. You can download the entire SAR Handbook (PDF) below.
