- Overview

Satellite imagery, including, visible, infrared, and water vapor types, captures Earth from orbit for analysis of land, weather, and climate. High-resolution images are provided by platforms like Google Earth Pro, USGS EarthExplorer, and Sentinel Hub, with NOAA offering near real-time, 10–15 minute updates for monitoring. 

While "live" video isn't publicly available, high-resolution daily images exist for urban planning and environmental monitoring.

1. Key Satellite Imagery Sources:

  • Google Earth Pro: A free, downloadable desktop program that provides high-resolution historical and 3D imagery.
  • Google Maps/Satellite View: Accessible directly through web browsers to view locations.
  • USGS Earth Explorer: An excellent source for free, high-quality data from Landsat and other satellite missions.
  • NASA Worldview: Provides interactive, near real-time imagery, allowing users to track wildfires, weather, and other events.
  • Copernicus Data Space Ecosystem: Provides free access to data from Sentinel missions.

 

2. Types of Imagery:

  • Visible: Shows Earth as the human eye sees it (daylight only), allowing for identification of land features and clouds.
  • Infrared: Measures heat, making it useful for both day and night monitoring of cloud cover, land, and water temperatures.
  • Water Vapor: Visualizes atmospheric moisture levels and flow.

 

3. Common Applications

  • Environmental Monitoring: Tracking deforestation, glacier changes, and natural disasters, such as floods or wildfires.
  • Urban Planning: Mapping land usage and infrastructure development.
  • Weather Forecasting: Tracking storms, clouds, and temperature changes.
  • Commercial Use: Providing up-to-date data for agricultural, mapping, and security sectors.

 

4. How to Access and Use:

  • EO Browser: A user-friendly tool to browse, visualize, and analyze data from many satellite missions.
  • SkyFi: A commercial alternative that offers recent, high-resolution satellite imagery.
  • Planet Labs: Offers high-frequency data for near real-time monitoring.
