Develop a web-based application to facilitate the comparison of ground-based observations with Landsat data. The application should allow users to define a target location, receive notifications of Landsat overpasses, and access corresponding Landsat SR data.
User-defined target location: Allow users to specify place name, latitude/longitude, or select a location on a map. Landsat overpass notifications: Provide timely notifications about Landsat satellite passes over the defined location. Landsat data access: Enable users to access and display Landsat SR data for the target location. Additional features: Consider cloud cover thresholds, data acquisition options, metadata display, spectral signature visualization, and data download/sharing.
Landsat missions provide a long-term dataset of Earth's land surface measurements. Comparing ground-based and Landsat data can support scientific exploration, education, and data validation. Existing applications lack a comprehensive solution for this purpose.
User experience: Optimize for mobile devices, ensure accessibility, and provide a user-friendly interface. Location selection: Allow users to define target locations based on their current location or multiple pre-defined locations. Mapping: Use a reference map to visualize the target location and Landsat scene extent. Landsat data: Integrate with Landsat data catalogs and APIs to access and process SR data. Notifications: Implement a system for sending notifications based on user preferences. Data visualization: Display Landsat data in a clear and informative manner, including spectral signatures and metadata. Data download: Allow users to download data in a suitable format (e.g., CSV). Overall, the application should empower users to explore Landsat data, compare it with ground-based observations, and gain insights into Earth's land surface.
