The images of my plant below illustrate this.

Each time a satellite captures imagery the nadir varies in its angle of shot. Having an angle “off nadir” provides a variation to the standard map view. This is the view from above the Earth directly to its center. However, it is possible to use varying angles of satellite imagery to get a three-dimensional understanding of an area.Ī key feature of satellite imagery is the nadir. Google Earth does have three-dimensional mountains, but even they sometimes fail to represent what is on the ground. Aside from city-based areas, there is limited three-dimensional views of buildings or features - all of which are crucial to monitoring and geolocating events. The satellite imagery we use for conflict analysis, geolocation, or any other form of investigation is a flat image. This is a satellite-based case study on vetting a three-dimensional view of an area via Google Earth, featuring examples from Syria, Yemen and Sudan. This is sometimes done in emergency situations - such as when an area has been hit by a natural disaster and new images would be of valuable assistance to the recovery and relief efforts.It has become abundantly clear that geolocation and remote sensing is fundamental to knowing what happens in conflict areas where it is often too dangerous for journalists, observers and analysts to be present on the ground. However, Google and its image providers do have the ability to rapidly integrate new images into the program. The images are acquired by satellites, processed by commercial image providers or government agencies, and then updated to the Google Earth image database in batches.

Large cities generally have more recent and higher resolution images than sparsely inhabited areas.Ī misconception exists among some people that the images displayed in the Google Earth program are live-updated directly from satellites. Most of the images in Google Earth were acquired within the past three years, and Google is continuously updating the image set for different parts of the Earth. Hope you enjoy!
