What if you could track how green your city really is? The Greenspace Detection App brings satellite imagery analysis right to your desktop, turning complex data into actionable insights about urban vegetation. This powerful tool automatically downloads and processes satellite imagery from cities worldwide, removing clouds and using advanced NDVI calculations to identify and visualize vegetation with remarkable accuracy. Whether you’re an urban planner, environmental researcher, or just curious about your city’s green cover, this app makes sophisticated environmental analysis accessible to everyone.
The magic happens through a scientifically rigorous approach that processes Sentinel-2 satellite imagery at 10-meter resolution, filtering out clouds and shadows to focus on what matters most – vegetation. Using the NDVI formula (NIR – Red) / (NIR + Red), the app categorizes vegetation into density levels from subtle growth to dense forests. What makes this particularly powerful is the temporal analysis feature, which compares annual vegetation patterns by selecting the best low-cloud scenes each month, then averaging the results to give you comprehensive insights into how your city’s green spaces are changing over time.
Beyond just pretty maps, this desktop application delivers real analytics that can drive meaningful environmental decision-making. With 50+ cities already mapped and predefined boundaries, you can instantly explore vegetation coverage statistics, track changes between years, and identify areas gaining or losing green space. The app handles all the complex satellite processing in the background while providing live progress updates, so you get scientific-grade environmental intelligence without needing to be a remote sensing expert. It’s democratizing environmental data analysis, one city at a time.
