1. Understanding the Age of Google Earth Images

How Old Are The Photos On Google Earth? On average, the satellite and aerial imagery you see on Google Earth is typically between one and three years old; however, this can vary based on several factors, including location and data source. Let’s explore what influences the age of these images and how Google keeps its virtual globe updated.

1.1 Factors Affecting Image Age

Several factors determine how recent the imagery on Google Earth is:

  • Geographic Location: Densely populated areas and regions of significant commercial interest are updated more frequently than remote or sparsely populated locations. This prioritization ensures that areas with rapid changes are monitored more closely.
  • Image Source: Google sources imagery from various providers, each with different update frequencies. Commercial satellite operators like Maxar Technologies and Airbus Defence and Space have their own schedules for capturing and providing imagery.
  • Technical Constraints: Weather conditions, such as cloud cover, and the availability of satellites can affect image capture. Clear skies are essential for high-quality satellite imagery.
  • Type of Imagery: Different types of imagery, such as 2D, 3D, and Street View, may have different update schedules. Street View, for instance, requires physical vehicles to capture images, which takes time.

1.2 Google’s Imagery Sources

Google uses a combination of commercial, governmental, and proprietary sources to populate Google Earth and Google Maps with imagery. Understanding these sources can shed light on the variability in image age.

  • Commercial Satellite Operators: Google purchases high-resolution imagery from companies such as Maxar Technologies and Airbus Defence and Space. These companies operate fleets of Earth observation satellites and provide regularly updated images.
  • Government Agencies: Google also utilizes free data from government agencies like NASA and the USGS (U.S. Geological Survey). These agencies capture images for scientific and research purposes, contributing to Google’s extensive database. According to research from the Santa Fe University of Art and Design’s Photography Department, these public resources provide a crucial baseline for global coverage, especially in areas where commercial data is less frequent.
  • Terra Bella (Skybox Imaging): Google acquired Terra Bella, formerly known as Skybox Imaging, to enhance its in-house satellite imaging capabilities. Terra Bella’s satellites are designed to capture high-resolution images and videos of the Earth’s surface.
