Mapping Methods With Unmanned Aerial Vehicles A Review

Abstract

A map is a bird's-eye view of a part of an area with a certain scale to be used for a specific purpose. All of the methods and processes used to create a map can be called mapping. In the map creation process, many images are combined into a whole. Although the images required for creating maps, were obtained in the past years by terrestrial methods, with the development of technology in time, they were taken from airplanes and balloons by aerial methods. Later, unmanned aerial vehicles (UAV) developed and became widespread in the field of mapping because they are more advantageous compared to other methods. In mapping with unmanned aerial vehicles, firstly the determined area is scanned and the take-off, landing points and potential dangers of the UAV are determined. A flight plan is made for the UAV. The UAV takes flight and photographs of the land are taken. Then, these photographs are uploaded to the computer to create a map, and the map is created by making corrections with the help of a map creation software such as PhotoScan and Pix4D. On the created map; Information such as position information of any point, direction information, height information of some objects in the area can be found. This mapping method with UAV is useful for many fields such as forestry, highway projects, agricultural fields, support works in natural disasters, military applications. The aim of this study is to examine the studies about mapping methods with UAV and to create a review article. In the light of this information, this article will make it easy to determine the materials and methods to be used in future studies.
