Analysis of the residual distortion and forward motion influence on the accuracy of spatial coordinates determination based on UAV survey

The purpose of this work is to study the operation of a non-metric digital camera Canon EOS 5D Mark III installed on a DJI S1000 octocopter, regarding the accuracy of spatial coordinates determination on images, and perform the identification and analysis of errors affecting the accuracy of stereophotogrammetry survey. During the experimental part, we conducted the stereophotogrammetric and aerial surveys of the areas including marked points. This served as a source of data for creating stereo models with their subsequent processing with the use of the Delta 2 software.

Development and investigation of UAV for aerial surveying

Aim. To develop an UAV for topographical aerial surveying goals, to explore its features, and comply with assigned tasks. Methodology. Scientists of the Institute of Geodesy in National University Lviv Polytechnic and manufacturers of Abris Design Group consistently designed and studied several models of UAVs, in order to create a perfect model, to make it possible to organize aerial surveying for topographical purposes. As a result of previous experimental work, technical requirements for the creation of UAVs were defined.

Analysis images from UAV on DPS "Delta" in the context of photogrammetric suitability for landscaping local significance

Development of air-technology, data communications and remote sensing involve the interest in applications of small Crewless Air Vehicles (CAV) in different  subjects of economy.

Hence the idea of the application of low-altitude images (taken from heights below 200 m) from crewless air vehicles for quick data updating of geoinformation of local (small) areas by photogrammetric methods.

Analysis of the results of the use UAV Trimble UX-5 for creation of orthophotomaps and digital model of relief

Purpose. The purpose of this paper is to analysis and research capabilities of unmanned aerial vehicle (UAV) Trimble UX5 to create orthophotomap and digital elevation models (DEM), as well as identifying and addressing possible shortcomings in the aerial survey and processing of aerial photographs. Methods. Before starting aerosurveying conducted reconnaissance of the area.

Technological features of creation of a large-scale topographical plan of Lviv city landfill using combined method

Purpose. The compliance with maintenance requirements of a landfill is an important factor that have affects on its functioning.  The functioning of Lviv city landfill started in 1959 and continued till 2016. According to evidences from various resolutions, regulations, and scientific publications, it was used and exploited with disabilities and did not meet environmental and sanitary standards. On May 30, 2016 a waste flow slide occurred in consequence of fire and its extinguishing.
