This work presents results of final part of the Bachelor work study program on Geoinformatics and geography at the Faculty of Science, Palacky University in Olomouc.
The aim of this thesis was to create an algorithm that could define the visibility of the sky for planning GPS measurements. The script was supposed to simplify the preparation of field measurements and especially to refine it.
Simplification of training is one way to save ground, where it had to be near the point of measurement accurately mapped. From this point would be to get the angles which would be obliged to enter the next step training measurement. The script should then further refine these angles. Will be mathematically calculated and their accuracy is longer a question of values entered into the algorithm.
After studying the available literature and resources available to find some that this work will be a little groundbreaking. There were no mentions of the same work, and similar applications have been very few references.
The first step was to develop a theoretical system, as the script will work. They were searched and tested methods that suit the characteristics of their work assignment.The second step was to create a test data that were provided to supervisor. And the last step was to build the script itself.
The input data is the point of the script, which is a real place on earth where the mission planning, digital model for either relief or surface. If the embedded digital model is a possible inaccuracy in such cities, because data on buildings in this model are not available. But if the use of digital terrain model, it is likely that measurements will be very accurate. Then it's just a question of accuracy with which the elements of the vision of preventing its location and parameters correspond to reality. The script uses only tools available in ArcGIS 10th The script can only be used with ArcInfo license, the highest possible software license. To build an algorithm was used scripting language Python.
The result of this work should be so robust that it can be free, and usable for the needs of the department.
