Rice Growth Stages with Google Earth Engine
This is a source code to produce a map for rice growth stages based on rice area in Google Earth Engine
The rice growth stages (RGS)is from the fusion between Sentinel-2, Landsat-8 OLI, and MOD13Q1 and the rice area are from median value from multitemporal Sentinel-1.
They are four class of RGS:
- Bare land (code=1)
- Vegetative stage (code=2)
- Reproductive stage (code=3)
- Ripening stage (code=4)
The rice is consist of three classes
- Rice area
- Urban/ Built up
- Water bodies.
The method is using supervised classification with three options of classifier: Random Forest, SVM, and CART
The javascript (js) is a file to run inside the code editor.
- Interactive_Map_RGS.js is for creating an interactive application with linking maps
- RGS_Fusion_DL.js is to download the RGS from using a fusion
- RGS_Fusion_JAVA_DL.js is to download the RGS from using a fusion for Java Island
- RGS_LS8_DL is to download RGS map with Landsat-8
- RGS_MOD13Q1_DL is to download RGS map with MOD13Q1
- RGS_S2_DL is to download RGS map with Sentinel-2
