ARSET - Calculating Spectral Indices for Land and Aquatic Applications Using QGIS
Start Date:
Feb. 27, 2025
End Date:
Feb. 27, 2025
Description:
This training will provide an overview of spectral indices for land and aquatic applications as they are calculated with a QGIS platform. Specifically, this training will begin with an introduction to the Normalized Difference Vegetation Index (NDVI), along with its calculation, uses, and applications in diverse thematic areas (agriculture, disasters, etc.). We will review additional land-based indices such as the Enhanced Vegetation Index (EVI), Soil-Adjusted Vegetation Index (SAVI), and Normalized Burn Ratio (NBR). Finally, we will concentrate on spectral indices primarily used in aquatic ecosystems, such as the Normalized Difference Chlorophyll Index (NDCI), Normalized Difference Aquatic Vegetation Index (NDAVI), Floating Algal Index (FAI), and Normalized Difference Turbidity Index (NDTI) for aquatic applications.
Not only will these sessions discuss the correct circumstances under which to use these indices, but participants will also take part in hands-on indices calculation over relevant study areas. Case studies using indices for land and aquatic applications will be highlighted.
Targeted Audience:
Primary target audience: Technicians and Land/Resource Managers
Secondary target audience: Students in Geography, Ecology, and other Earth-observing fields
