Sample collection interface

A script was written for the Google Earth Engine Code Editor interface to collect validation samples from the maps independent of the training and verification process. This interface allows to distribute the work from the draw of the validation pixels among all the participating interpreters and facilitates the labeling year by year. Each interpreter is assigned a set of validation samples and must verify membership to a class from the image time series and imputing the class to which the sample belongs year by year.
