Zoe Xirocostas and Angela Moles at the University of New South Wales have developed a great app for training researchers to visually estimate leaf damage. We recommend all of you to have a look, and train yourself before you estimate leaf damage in the field 😊
The app presents randomised images of leaves with different amounts of damage. You have to visually estimate damage on those leaves using a slider tool under the image. After submitting your estimate, the correct answer is displayed. Estimates that are within 0-1% of the actual answer are considered accurate. After estimating 10 images, a running average of your estimate accuracy is displayed. Your training will continue until the running average of your last 10 images reaches 98-100% accuracy. Once you have completed your training you will see your progress displayed in a graph.
