Satellite-Based Reforestation Monitoring for Tropenbos Ghana

Logo for Tropenbos Ghana featuring a stylized green globe with trees and wavy lines inside, and the organization name in black text.

Tree Trackers is a reforestation monitoring platform developed through Stanford Engineers for a Sustainable World in collaboration with Tropenbos Ghana. The system combines Sentinel-2 satellite imagery and Google Earth Engine processing with a browser-based dashboard for analyzing vegetation health and change across restoration sites.

Users can define areas of interest, compare vegetation conditions over time, and review site-level metrics such as NDVI and vegetation coverage. The platform was designed to support scalable monitoring between field visits and help Tropenbos staff assess restoration progress across geographically distributed sites.

The Tree Trackers dashboard is a browser-based interface for monitoring reforestation sites using Sentinel-2 satellite imagery processed in Google Earth Engine. Users can define areas of interest, select analysis dates, visualize NDVI-based vegetation conditions, and review changes in vegetation coverage over time. Built with Next.js and React, the dashboard translates geospatial analysis into a more accessible tool for Tropenbos Ghana staff to remotely assess restoration sites and identify areas that may need closer field investigation.
