Exploring Earth's Evolution Through Historical Satellite Imagery

In space, a fleet of satellites has been orbiting Earth for decades, capturing detailed images of our changing landscape. From the 1970s to today, these satellites have served as powerful tools, providing essential data that helps us understand how landscapes, weather patterns, and city growth have evolved. This information is invaluable for businesses looking to make informed decisions based on environmental and geographical insights.

The Landsat Program: Pioneering Satellite Observations of Earth's Surface

Imagine witnessing the birth of a city, the retreat of a glacier, or the transformation of a forest—all from space. Landsat’s historical imagery allows us to do just that. Whether tracking urban sprawl, monitoring agricultural productivity, or assessing environmental changes, these satellites have become our time machines, bridging the gap between past and present.

1. Landsat-1: Revolutionizing Earth Observation Since 1972

  • Launch Date: July 23, 1972
  • Mission: Landsat-1, the inaugural satellite of the Landsat program, revolutionized our understanding of Earth’s surface. Armed with multispectral sensors, it captured images across different wavelengths, unveiling patterns in land cover, vegetation health, and urban growth.
  • Legacy: Landsat-1 set the stage for subsequent missions, providing a consistent record of our planet since the days of bell-bottoms and lava lamps.

2. Landsat-2 to Landsat-9: Continuously Enhancing Earth Imaging Capabilities

  • Years of Operation: From the late 1970s to the present day
  • Frequency: These satellites revisit Earth’s surface every 14 to 16 days.

Beyond Landsat: Exploring Other Historical Satellite Programs

1. SPOT Satellites: High-Resolution Earth Imagery for Over Three Decades

  • Launch Date: The first SPOT (Satellite Pour l’Observation de la Terre) satellite was launched in 1986. SPOT 7 is the latest that was launched in 2014.
  • Spatial Resolution: SPOT satellites provided high-resolution imagery (ranging from 2.5 meters to 20 meters).
  • Applications: SPOT data were used for land cover mapping, urban planning, agriculture, and environmental monitoring.
  • Legacy: SPOT paved the way for commercial Earth observation, offering detailed views of our changing landscapes.
Overview of the SPOT Program
SPOT Mission Launch Year Panchromatic Resolution Multispectral Resolution
SPOT 1 1986 10 meters 20 meters
SPOT 2 1990 10 meters 20 meters
SPOT 3 1993 10 meters 20 meters
SPOT 4 1998 10 meters 20 meters
SPOT 5 2002 2.5 to 5 meters 10 meters
SPOT 6 2012 1.5 meters 6 meters
SPOT 7 2014 1.5 meters 6 meters


  • Panchromatic: This mode captures images in black and white.
  • Multispectral: This mode captures images in multiple wavelengths of light.

2. NOAA Satellites

  • NOAA-6 to NOAA-19: NOAA (National Oceanic and Atmospheric Administration) polar-orbiting satellites have been capturing weather and environmental data since the 1970s.
  • Data Types: NOAA satellites provide critical meteorological information, including cloud cover, sea surface temperatures, and atmospheric profiles.
  • Impact: Their data aid in weather forecasting, climate studies, and disaster management.

GOES (Geostationary Operational Environmental Satellites) is one of NOAA’s satellites that was launched in 1975.

    • Unlike polar-orbiting satellites, GOES  satellites remain fixed above specific regions.
    • Weather Monitoring: GOES provides real-time imagery of weather patterns, storms, and atmospheric phenomena.
    • Legacy: GOES has been instrumental in severe weather prediction and monitoring.

Expanding Perspectives with Aerial Imagery

While satellite imagery provides a comprehensive view from space, aerial imagery offers a closer, more detailed perspective of the Earth’s surface. Utilizing aircraft and drones, aerial photography captures high-resolution images that are crucial for urban planning, real estate, and environmental monitoring. These images complement satellite data by providing additional clarity and precision, enhancing our understanding of specific areas and facilitating more informed decision-making. Additionally, archived aerial images serve as historical records, allowing us to trace the development of landscapes, urban expansions, and environmental changes over decades.

Here are some notable archives that house extensive collections of historical aerial photographs:

  • U.S. Geological Survey (USGS) EarthExplorer : The USGS EarthExplorer is an online search, discovery, and ordering tool for various datasets, including historical aerial images. This archive includes aerial photographs dating back to the 1930s, covering the United States and other areas globally.
  • The National Collection of Aerial Photography (NCAP) : Based in Scotland, the NCAP is one of the largest collections of aerial imagery in the world, housing millions of aerial photographs, including those of the UK, taken during reconnaissance missions since before and during the Second World War up to the present day.
  • Library and Archives Canada (LAC) : LAC holds a significant collection of aerial photographs primarily from the National Air Photo Library. The archive includes millions of aerial images covering all regions of Canada, dating back to the 1920s. These photographs are useful for anyone studying changes in landscapes, environmental assessments, or historical land use.
