Littoral monitoring using unmanned aerial vehicle

Abstract

The authors explore the littoral as a natural phenomenon using geodetic methods. Littoral is an areal object and is closely related to coastal abrasion. The abrasion destroys the coastal zone. Preventing the destruction of the coastal zone requires monitoring the littoral, forming its model and that of littoral dynamics. Littoral and dynamo models enable developing recommendations for protecting the coastal zone. Having remote sensing data only we are unable to perform littoral monitoring efficiently. It does not ensure the accuracy and relevance of the state of the coastal zone. The monitoring task can only be solved with the use of integrated geodetic support.This support includes geodetic work and the use of an unmanned aerial vehicle for monitoring the littoral. The authors explore littoral as a natural phenomenon. A new method of obtaining spatial coordinates using images obtained from UAVs is described. The essence of the methodology is determining spatial coordinates using single images. The technology includes the use of water level sensors to define the exact height of the survey. The methodology involves the use of satellite navigation equipment to determine the coordinates of the camera at the time of shooting. Special here is that the littoral boundary is a fuzzy object calculated on the basis of statistical data. The research shows that the geodetic technologies are the basis of the integrated one. The authors providethe analysis of the situation and suggest measures for monitoring the coastline.

Application of Newton’s method to solve optimization geodetic tasks

“…In its turn, the development of geodetic instruments has made it possible to solve many geodetic problems at a new technological level. So in his works, [1,2] used satellite and laser equipment to solve classical geodetic problems. Thanks to modern scanning systems, robotic total stations, a surveyor can obtain a huge array of data about the object in a short period.…”

Applying Newton’s second order optimization method to define transition keys between planar coordinate systems

“…The development of geodetic instruments has put the solution of many geodetic problems at a new technological level. So in his works A.A. Kuzin and others [1], as well as Tsvetkov V. Y., & Oznamets V. V [2] used satellite and laser equipment in solving classical geodetic problems. Thanks to modern scanning systems, robotic tacheometers, the surveyor in a short period of time is able to obtain a huge array of data about the object without direct contact with the object [3].…”
