Automated recognition of selected terrain features from their cartographic representation
Sykora, Matúš ; Bayer, Tomáš (advisor) ; Brodský, Lukáš (referee)
Automated recognition of selected terrain features from their cartographic representation. This diploma thesis is dedicated to automatic classification of selected terrain shapes and their cartographic representation. The main aim of this thesis is to design methodological approach for automatic recognition of terrain shapes (hills and valleys) with the use of Machine Learning (Deep Learning). The first part of suggested method divides rough terrain segmentation into two categories, which will be then classified with convolutional neural network. The second part of the thesis is dedicated to the very classification of pre-segmented terrain shapes using Machine Learning. Both parts of the processing are using photos SRTM30 as an input data. The whole proposed method was developed in Python programming language with the usage of Arcpy, TensorFlow and Keras libraries. Keywords: Digital cartography, GIS, terrain shapes, Machine Learning, Deep Learning, recognition, classification, segmentation

This thesis deals with factors influencing the average speed on Czech roads. Curvature and inclination of the slopes were selected among the main factors influencing the average speed. Until now, these factors have been considered at discrete intervals, not as continuous functions. The function for calculating the curvature is based on ČSN 73 6101, where the equation with all variables is directly defined. The functional relationship for the movement of vehicles in sloping terrain was created from data from scientific articles. Therefore, an algorithm was implemented in this thesis, which can automatically evaluate the average speed on the road network. Python was used to implement this algorithm. Furthermore, there is a testing section for travel times, which is validated using route planners and also supported by extensive field research. Testing took place in GIS using network analysis methods. Testing has shown that the inclusion of curvature and inclination will significantly improve the calculation of travel times. key words: network analyst, curvature, gis, algorithm
Simplification of rivers based on the spatial reduction method
Mazur, Dominik ; Bayer, Tomáš (advisor) ; Brůha, Lukáš (referee)
This master thesis is focused on cartography generalization of a rivers using collapse and partial collapse method with the usage of straight skeleton data structure. The proposed method was designed for large scale maps in geographical view and for medium scale maps in cartographic view (till 1 : 100 000). The thesis is focusing on width of a river as stand alone criteria for generalization decision. The presented solution represents set of a criteria which decides on generalization of a river. The presented thesis also solves problematic situations that exist on a river such as islands, junctions, shoulders or bifurcation. The thesis also includes proposed generalization algorithm which is using straight skeleton data structure. The algorithm is implemented in C++ programming language in Microsoft Visual Studio IDE. The algorithm uses external libraries Qt and CGAL (Computational Geometry Algorithms Library) for functioning. Algorithm results are saved in ESRI geodatabase with the usage of Python 2.7 programming language and external library ArcPy. Water areas from ZABAGED were chosen as appropriate data for testing. Achieved results of generalization are presented on test data for various scales and they are compared with base maps of Czech Republic. Keywords: digital cartography, cartography...
Assessment of hydraulic reliability of drainage system in urban area and solution of extra-urban storm water.
Šebek, Josef ; Macsek, Tomáš (referee) ; Hlavínek, Petr (advisor)
This diploma thesis presents the topic of urban drainage systems. The first theoretical part contains methods and options for urban drainage systems, stormwater management, blue-green infrastructure (BGI) in urban areas and introduction of numerical modelling of sewerage systems. The application of modelling platforms is further described in the feasibility study in the practical part of this thesis. By using the simulation model, the study assesses the hydraulic reliability of the drainage system in the city of Jedovnice in the Czech Republic, identifies hydraulic issues and their causes on the urban drainage system. The second part of the study assesses extra-urban stormwater inflow from fields around the city caused by heavy rainfalls, which causes local flooding in the urban area. The identification as well as proposed solutions and capital expenditures, their comparison and recommendation of the optimal solution are included in the study.
GIS in Building Practice
Laciga, Jan ; Vaňková, Lucie (referee) ; Krejza, Zdeněk (advisor)
This diploma thesis deals with the possibilities of using the geographic information systems in construction practice with a focus on facility management of buildings. The goal is to show the possibilities of use and the advantages that GIS offers in the construction industry thanks to its analytical and visualization capabilities. In the theoretical part there are basic terms such as BIM, Industry 4.0, GIS and facility management described. Furthermore, the possibilities of using GIS in construction industry and facility management of buildings are addressed. In the practical part the procedure of creating a GIS database for facility management is processed, specifically on information model of BUT FAST campus premises.

Mapování skalních výchozů v okolí PR Klenov na základě dat leteckého laserového skenování
Stuchlík, David
This bachelor thesis deals with the possibilities of using a precise digital terrain model created from data obtained by aerial laser scanning in order to identify terrain formations with an emphasis on the rock outcrops. The measurements were made at the PR Klenov site and the results of the analyzes were compared with the rock outcrops targeted by GPS devices. Digital model analysis was performed in ArcGIS 10.3., where various methods (geomorphometric analysis) were used to detect rock outcrops. The aim was to determine the accuracy of aviation laser scanning and also to find the most accurate method for detecting rock outcrops.
Analýza území v prostředí GIS pro účely komplexních pozemkových úprav
Driml, Tomáš
This thesis deals with geoinformation analysis of comprehensive landscaping. The thesis compares calculations of the long-term soil loss using different digital terrain models and topographical factors. Subsequently the thesis focuses on the rating of the drain and erosive ratio on the basis of the analysis of the current status of the examined area, that is the circumference of the outcoming comprehensive landscaping in Kunovice cadastral area under the conditions of the conventional agriculture scenario. These resource materials helped the diploma thesis to design anti-erosion measures including the main agricultural roads and the system of ecological stability that was extended with the interactive elements for the needs of these measures. Afterwards their efectivity was succesfully measured. Results of plans are designed in the next part of the thesis to the form of map outputs and in the discussion were debated contributions of the plan from the perspetcive of the opening the water regime of the landscape, the danger of erosion and the ecological stability.
