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). Link to ATBD
How to use
First, you need to copy these scripts (including those in p04 folder) to your Google Earth Engine (GEE) account.
Pre-processing
Step01: build stable pixels from Colleciton 6 and save a new asset
Step02: export balanced training samples for each region
Step03: export trained samples for each year
Classification
Step04: classify and export classification for each region
Post-processing
Step05: merge classification of each region and apply Gap fill filter to remove NODATA
Step06: spatial filter
Step07a: temporal filter-3year
Step07b: filter regeneration on rare classes
Step07c: stabilizes natural classes
Step08a: temporal filter-4year
Step08b: temporal filter on first and last year
Step08c: temporal filter-5year
Step09a: temporal filter on first and last year on rare classes
Step09b: filter rare classes on the middle years
Step09c: filter minimum areas of transitions
Step09d: apply HAND filter on wetlands
Step09e: remove forest regeneration in forest plantation from Sentinel classification
Step10a: classify Sandbank Vegetation
Step10b: remove forest regeneration on last years on agriculture
Step10c: spatial filter
