The article reflects the method of orthophotomap decivetion. The flow diagram of UAV data processing in Photomod is presented. The final processing results are presented in the form of an orthophotomap. The technology for constructing point objects for further error analysis is presented. The calculation of the plotted points in Excel for further error analysis was performed. Errors based on the tolerances that are proposed in the instructions for topographic survey are analyzed.
