Lecture 4 - 12 NOV. 2020
Objective: learn to use satellite imagery RED/NIR bands to calculate indices (NDVI) that correlate with vegetation status
Dataset : forestFireAgordo2018
- Normalized Vegetation Index (NDVI) - calculation from RED and INFRARED reflectance bands coming from satellite imagery
- Application of NDVI to assess vegetation stress and disturbance - plotting in QGIS - exporting in Excel, checking R" using a trend line
- connecting to WMS/WFS/WCS services - see tutorial Working with WMS Data
- Zonal statistics - see tutorial Sampling Raster Data using Points or Polygons (QGIS3)
