Detecting changes that happened in the field during the last one-two weeks or one-two months or even a couple of years helps to get insights about crop development.
Relative variation factor or Relative Variation Index can be used to:
- locate spots with similar performance across 5-10-20 years and place the trials in areas with similar conditions to reduce the probability of mistake
- track the changes during the season and evaluate crop performance during the growth
- recognize the damaged areas after a weather disaster or a disease or a pest attack and calculate damaged areas
- detect the difference between the last two images and control the crop performance.
