Applications: Satellite

With the growing constellation of commercial earth-observation satellites, there has been an associated growth in the inclusion of spatial data in our everyday lives. Once the realm of surveyors and rocket scientists, GPS technology is now in our automobiles, wrist watches, and cell phones, and is becoming increasingly tied to image data, be it a picture of the Earth or the front of the restaurant we just made cell phone reservations with while stuck in traffic.

To enable such generalized use of aerial, satellite and ground-based imagery, the collected images need to be associated with ground coordinates in order to correctly position the imagery in relation to the Earth.

To ensure that the image is in the right position, and that the correct image of the restaurant comes up on the screen of the onboard navigation system in your car, it is necessary to provide accurate ground coordinates to tighten the accuracy of the overhead imagery.

This is the role of CompassData, and we are continually collecting new control across North America and around the world to provide accurate coordinate data to support an increasing variety of applications.
