The project begun by collecting all the information connected with geodesy, map projections and Global Navigation Systems. In the same time theoretical part covers also manuals and specification of further used tools like FARO Laser an GNSS Receiver. After get to know about theoretical part the next step was to work with outdoor devices. Before do all surveys it has to be known all rules connected with health and safety. Then it has to be done leveling of the FARO Lasers holder. Afterwards on the top it was put GNSS Receiver. It was working for a few minutes to collect as much information as necessary to know the position. Next step was to start the scanning of laser and do the photos. The same was done with the second position on the campus. When the outdoor work was done all parts had been taken to a magazine for further users. After the outdoor work the time comes to desk work. Before this task it has to be known computer programs that will be used in the project. To do a post-processing it was chosen the RTKLIB program. For the map projecting the best option was CloudCompare. With help from manuals and tutorials the work on a map can go ahead. At least after all tasks the final map was ready for the further use.
