My aim is to compare two images of NBR index obtained by Landsat 8 for two dates: April the 1st and October the 26th (the beginning of the wildfires period and the ending of the period). After that I want to compare the difference NBR image with MODIS vector products (as it's shown below) The "blue" pic is a result of ISODATA process (for detecting of the areas with the biggest difference which are supposed to have been burned). The questions are:
- Is it a good idea to use ISO DATA for this purpose (I obtained just 3 classes).
- How I can compare my vector data (MODIS areas) and raster data (Landsat 8) to find the difference between burned area?
