New UAV Technologies and the Need to use them in Obtaining Spatial data Through Remote Sensing in the Geography of Iran

Drones are unmanned aerial vehicles (UAV) that have entered the field of surveying engineering with the rapid development of science and technology. The important factor in the development of UAVs is that they have the advantages of miniaturization, high maneuverability, and the ability to perform difficult tasks compared to manned aircraft. By improving the knowledge related to sensors and equipping drones with modern sensors, the process of remote sensing by these efficient drones has been gradually operationalized. UAVs are equipped with three infrastructures, air, ground and advanced information collection system to send location information remotely. The ability to fly at a low altitude allows drones to be successful in sending high resolution images and the data received from them is very accurate. Also, the use of drones provides the necessary ground for using several sensors simultaneously, which is effective in increasing the speed of accurate measurement of a geographical area. Since the country of Iran has a wide area and is very diverse in terms of geographical features (forests, pastures, deserts, seas, etc.), it is necessary to use new drone technologies for mapping and obtaining data. In this article, an attempt has been made to examine the new technologies of smart drones for accurately receiving spatial information and remote sensing, and to explain to the audience how to optimally use this spatial information.
