The use of uavs for geospatial data collection

Abstract

In this article, the use of UAVs for geospatial data collection was analyzed. Nowadays, inexpensive UAVs equipped with high-resolution cameras, laser scanners, GNSS/RTK receivers and sensors are capable of making sophisticated and spatially correct maps of survey-grade accuracy with minimum human control. UAVs are bringing the revolution to cartography making it truly real-time. This article contains the information about the workflow, analysis of factors, which influence accuracy, accuracy assessment of one of the most popular drones, comparison of GPS ground topographic survey and aerial UAV topographic survey, suggested improvements to the modern civilian drones and skills that professionals in GIS, geodesy and cartography have to acquire nowadays.
