I need to produce a landuse classification map for each year from 1984 to 2019 using Landsat data. I have classified the 2019 image using Google Earth Engine. How can I use the training data and code I have for 2019 and apply it from 1984 to 2018 instead of training/running a code for each image individually. And how can I represent the landuse on a graph showing area of each class for each image using google earth engine.
