Description: during the day, which allows us to work with a smaller, more efficient crew. Lidar uses a scanning laser mounted on an aircraft, and coupled with GPS and an inertial measurement unit, creates a Digital Elevation Model (DEM) of the project area. The DEM can be produced with all culture left

Impact of Position Errors on Path Loss Model Estimation for Device-to-Device Channels
Fig. 6: Normalized histograms of the GPS distances measured at each true distance.
Encyclopedia of Solid Earth Geophysics
The accuracy of GPS distance mea- surements is lower than their precision because of propa- gation effects, including interference from signals reflected from nearby objects (known as multipath), but it has proved possible to determine horizontal ground dis- placements to within a …
Advances in Manufacturing Technology
Practices indicate the traditional GPS distance measurement model has a relatively large error.
Self-adjusting method for efficient GPS tracklog compression
However the traditional GPS distance measure used to evaluate each step is not directly applicable in use-cases when compu- tational power of the device is as low as a mobile phone.
