Perennial Crops

About

This folder contains the scripts to classify and post-process the Other Perennial Crop class.

We recommend that you read the Agriculture Appendix of the Algorithm Theoretical Basis Document (ATBD), since important informations about the classification methodology can be found in there.

How to use

First, you need to copy the scripts in this folder and in the utils folder to your Google Earth Engine (GEE) account.

Then, in your GEE account, go to the Assets tab, create the following directory structure:

• MAPBIOMAS/C7/AGRICULTURE/PERENNIAL_CROPS/RESULTS

and create one Image Collections:

• MAPBIOMAS/C7/AGRICULTURE/PERENNIAL_CROPS/RESULTS/RAW

Classification

To run the classification, follow these steps:

1. Open the script agriculture/perennial_crops/01_classification.js;

2. On line 19 (variable api), set the path to the api.js script you copied to your GEE account;

3. On line 24 (variable output), set the output path for the classification results;

4. On line 27 (variable years), set the years you want to classify;

5. On line 34 (variable tiles), set the WRS (path and row) you want to classify;

6. On line 59 (variable periods), set the periods of the region you want to classify (more information about that you can read on the ATBD Agriculture Appendix);

7. On line 84 (variable imageCollection), set the collection you want to use to create the mosaics;

8. On line 87 (variable reference), set the path to your reference map that will be used for sampling;

9. Run the script.

Post-processing

To apply the temporal and spatial filters, follow these steps:

1. Open the script agriculture/perennial_crops/02_spatial_temporal_filter.js;

2. On line 18 (variable input), set the path to the raw classification result;

3. On line 21 (variable output), set the path for the filtered result;

4. Run the script.
