🌍 Landwatch 🚀

Welcome to the Landwatch — an innovative web-based application designed to seamlessly connect space-based satellite data with ground-based observations. Whether you’re a scientist, student, land manager, or an earth enthusiast, our app allows you to track Landsat satellite overpasses, access critical real-time environmental data, and compare it directly with your own measurements — all in one place.

🔥 Features

• Track Landsat Overpasses
  Define a target location and receive notifications when Landsat satellites (Landsat 8 & 9) will pass over your area.

• Access Surface Reflectance Data
  Instantly access and download Landsat Surface Reflectance (SR) data for your location to monitor changes in Earth's surface.

• Compare with Ground-Based Observations
  Compare satellite SR data with your own field measurements to validate and explore environmental changes in real-time.

• Interactive Map Integration
  Select your target location on a dynamic map, and visualize the Landsat scene extent, including a 3x3 grid of 9 Landsat pixels centered on your location.

• Customizable Notifications
  Set custom alerts based on lead time for satellite passes and cloud coverage thresholds to get data tailored to your needs.

• Visualize Spectral Data
  Display and analyze Landsat SR data in graph form to better understand the spectral signature of Earth's surface.

• Download Data
  Export valuable Landsat SR data and metadata, including acquisition date, satellite info, cloud cover, and more, in CSV format.
