NASA’s Applied Remote Sensing Training Program (ARSET) has opened a new open, online webinar: Calculating Spectral Indices for Land and Aquatic Applications Using QGIS. This training, delivered in English and Spanish, will provide an overview of spectral indices for land and aquatic applications as they are calculated with a QGIS platform. 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.
If you would like to join us or pass along to colleagues who will find it useful, please do so. Please see the training details and registration information below.
Calculating Spectral Indices for Land and Aquatic Applications Using QGIS
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.
This training is also available in Spanish.
Learning Objectives: By the end of this training attendees will be able to:

El Cálculo de Índices Espectrales para Aplicaciones para Tierras y Acuáticas Usando QGIS
Esta capacitación presentará un resumen general de los índices espectrales para aplicaciones terrestres y acuáticas y cómo calcularlos utilizando la plataforma QGIS. La capacitación comenzará con una introducción al Índice de Vegetación de Diferencia Normalizada (Normalized Difference Vegetation Index o NDVI)), junto con su cálculo, usos y aplicaciones en diversas temáticas (agricultura, desastres, etc.). Repasaremos otros índices para aplicaciones terrestres, como el Índice de Vegetación Mejorado (Enhanced Vegetation Index o EVI), el Índice de Vegetación Ajustado al Suelo (Soil-Adjusted Vegetation Index o SAVI) y el Índice Normalizado de Área Quemada (Normalized Burn Ratio o NBR). Por último, nos enfocaremos en los índices espectrales utilizados principalmente en ecosistemas acuáticos, como el Índice de Clorofila de Diferencia Normalizada (Normalized Difference Chlorophyll Index o NDCI), el Índice de Vegetación Acuática de Diferencia Normalizada (Normalized Difference Aquatic Vegetation Index o NDAVI), el Índice de Algas Flotantes (Floating Algae Index o FAI) y el Índice de Turbidez de Diferencia Normalizada (Normalized Difference Turbidity Index o NDTI) para aplicaciones acuáticas.
Se discutirán las circunstancias correctas para utilizar estos índices y los participantes también participarán en cálculo de estos índices sobre áreas de estudio relevantes. Se destacarán estudios de caso que utilicen índices para aplicaciones terrestres y acuáticas.
Objectivos de Aprendizaje: Al final de esta capacitación, los participantes podrán:
