In this tutorial, you’ll learn how to estimate vegetation biomass using MODIS GPP and NPP datasets in Google Earth Engine (GEE). We walk step-by-step through the full workflow, from defining the Area of Interest (AOI) and time range to calculating NPP8, converting it to biomass, visualizing results, and creating time-series charts.
📌 What you will learn in this video:
How to load MODIS GPP (MOD17A2HGF) and MODIS NPP (MOD17A3HGF) in Google Earth Engine
How to compute NPP8 from 8-day GPP products
Converting NPP to above-ground biomass using empirical multipliers
Reprojection and spatial resolution handling in GEE
Biomass visualization using color palettes and legends
Creating biomass time-series charts for environmental monitoring
Practical applications in climate change, forestry, carbon stock, and ecosystem productivity analysis
🌍 This method is widely used in remote sensing, environmental science, GIS, forestry, agriculture, and carbon cycle studies.
💻 Tools & Data Used:
