Welcome to the Landsat Analysis Tool, a project developed for the NASA Space Apps 2024 Hackathon. Our team worked on the challenge titled "Landsat Reflectance Data: On the Fly and at Your Fingertips" to bring real-time Landsat satellite data to users in an accessible and interactive way. The application allows you to visualize and analyze satellite imagery and reflectance data at a user-selected location on the map.
Our primary goal was to create a tool that enables anyone, from researchers to students, to:
- Access Landsat imagery and surface reflectance data.
- Understand how satellite imagery can be used for real-world applications.
- Get the data easily without complex processing requirements.
- Interactive Map: Users can select a point of interest directly on the map.
- Satellite Overpass Information: Find out when the next satellite pass over the selected location will occur.
- Notification System: Receive email alerts for upcoming satellite passes at your selected location.
- React.js: Utilized for building a dynamic and interactive user interface.
- React-Bootstrap: For creating responsive UI components.
- Leaflet.js & React-Leaflet: Provides mapping capabilities to allow users to select geographic coordinates interactively.
- Node.js & Express.js: Handles all backend logic, processes API requests, and integrates with NASA's APIs.
- Axios: Used for making HTTP requests to NASA and USGS APIs.
- NASA Earth API: To retrieve satellite imagery data.
- USGS API: To obtain further satellite data, such as reflectance.
- Stadia Maps: To provide interactive map tiles for selecting locations.
Our project addresses the "Landsat Reflectance Data: On the Fly and at Your Fingertips" problem statement by offering:
- Easy access to Landsat surface reflectance data without requiring advanced GIS software or expertise.
- Real-time exploration of different regions around the globe, helping users to visualize the environmental data instantly.
- Interactive visualization through an integrated map-based UI that ensures anyone, regardless of technical skills, can utilize Landsat satellite data effectively.
