Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and ...
This is a list of satellite map images with missing or unclear data. Some locations on free, publicly viewable satellite map services have such issues due to having been intentionally digitally obscured or blurred for various reasons of this. [1] For example, Westchester County, New York asked Google to blur potential terrorism targets (such as ...
Aerial Archaeology involves interpretation and image analysis of photographic (and other kinds of images), in field research to understand archaeological features, sites, and landscapes. It enables exploration and examination of context and large land areas, on a scale unparalleled by other archaeological methods.
The National Collection of Aerial Photography is a photographic archive in Edinburgh, Scotland, containing over 30 million aerial photographs of worldwide historic events and places. From 2008–2015 it was part of the Royal Commission on the Ancient and Historical Monuments of Scotland [1] and since then it has been a sub-brand of Historic ...

Satellite imaging companies sell images by licensing them to governments and businesses such as Apple Maps and Google Maps .
The earliest known world maps date to classical antiquity, the oldest examples of the 6th to 5th centuries BCE still based on the flat Earth paradigm. World maps assuming a spherical Earth first appear in the Hellenistic period. The developments of Greek geography during this time, notably by Eratosthenes and Posidonius culminated in the Roman ...
Sensors on Earth observation satellites often take measurements of emitted energy over some portion of the electromagnetic spectrum (e.g., UV, visible, infrared, microwave, or radio). [ 1 ] The invention of climate research through the use of satellite remote telemetry began in the 1960s through development of space probes to study other planets.
The Blue Marble is a photograph of Earth taken on December 7, 1972, from a distance of around 29,400 km (18,300 mi) from Earth's surface. [1]The original image (NASA designation AS17-148-22727) was taken by either Ron Evans or Harrison Schmitt of the crew of the Apollo 17 spacecraft on its way to the Moon, and showed Earth with the South Pole facing upwards; since then, a cropped and rotated ...
