Atlantic Forest

Developed by ArcPlan - mrosa@arcplan.com.br

About

This folder contains the scripts to classify and post-process the Atlantic Forest Biome.

We recommend that you read the Atlantic Forest Biome Appendix of the Algorithm Theoretical Basis Document (ATBD).

How to use

First, you need to copy these scripts (including those in utils folder) to your Google Earth Engine (GEE) account.

Pre-processing

Step01: build stable pixels from Colleciton 4.1 and save a new asset. Step02: calculate area proportion for each class to each region that will be used to generate training samples Step03: export balanced training samples for each region Step04: export training samples for each year

Classification

Step04a: export classification for each region

Post-processing

Step05: merge classification of each region and apply Gap fill filter to remove NODATA Step06a: create asset with 10 an 12 changes in classification Step06b: apply incident filter to remove pixels with 10 an 12 changes from forest class Step07: apply temporal filter Step08: apply spatial filter Step09: apply frequency filter
