This introductory webinar will cover the fundamentals of Solar Induced Fluorescence (SIF) and LIDAR, their applications, and an overview of different satellite data sources that are openly available. In addition, it will also include a step-by-step guide on how to access, open, and interpret SIF and LIDAR data.
SIF is a relatively new satellite retrieval, providing a direct measurement related to plant photosynthetic activity. It serves as a strong proxy to gross primary production (GPP), capturing dynamic responses of vegetation to stressors such as drought and temperature.
LIDAR is a system that illuminates a target and measures distance through the time taken for a pulse to reflect back to the sensor. LIDAR can be used to generate topography and vegetation height maps and retrieve digital elevation data necessary for flood modeling and vulnerability, along with risk analysis. They are valuable datasets for post-disaster assessment of debris deposition, vegetation loss, and flooding.
Course Format
The online training will be divided into four parts and two seperate sessions, which take place at different times. Each part will be two hours long. The first session will be conducted in English and the second session will conducted be in Spanish.
The online training will take place on March 16th, 18th, 23rd and 25th, 2021.
