The visualisation process uses a Vector Map Level 2 (VML2) that corresponds, in terms of information content to a Military Topographic Map in a scale of 1:50 000. Data visualisation was performed by means of developing the relevant scripts. The objective was to obtain a visualisation result, that would be as similar as possible to an analogue topographic map of the M755 series. The automated visualisation was analysed by comparing each map symbol, developed in both tested GIS servers and juxtaposing it with the instruction for manual editing M755 series maps. The obtained maps are displayed in form of an interactive geoportal. The authors analysed the time of generating corresponding map fragments at various parameters (area size, number of requests processed simultaneously and the number of required layers). The results of the analysis demonstrate that the discussed GIS servers present the map symbols from the analogue map correctly in more than 90% of cases. The tests of map generating time showed a significant advantage of Geoserver, which was better than the Mapserver software in nearly all cases.","PeriodicalId":107301,"journal":{"name":"2019 International Conference on Military Technologies (ICMT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131087363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the quality of optical images would influenced by cloud. Radar is known to be very sensitive to vegetation physiognomy and biomass. The sensitivity of synthetic aperture radar (SAR) to the structural features of terrain leads to landcover classification into simple and easily interpreted structural classes. In this paper, the potential of using free of charge Sentinel-1 SAR imagery for land cover mapping in the Moravian-Silesian region, is investigated. The images recorded in 2018 were used for a per-pixel and object-based classification of agricultural land. The per-pixel classification was performed by the maximum likelihood algorithm, the object-based classification then using the support vector machine algorithm. The legend was taken from the Land Parcel Identification System (LPIS) and contained the following three classes – grassland, arable land and a class that involves hop fields, vineyards, and orchards. Post processing of the classification results has been done using the confusion matrix (also known as error matrix) and corresponding overall accuracy and Kappa coefficients of all the classification methods have been calculated. Significantly better results were achieved through object-oriented classification. In both areas of interest, the highest processing and user precision was achieved for the arable land class.","PeriodicalId":107301,"journal":{"name":"2019 International Conference on Military Technologies (ICMT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133307404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Suitable SW tools offer several types of plots and diagrams and enable calculation of measurements of central tendency, variability and concentration, and to test distribution and differences between circular variables. A short review of basic statistical indicators and usual tests is provided. The application is demonstrated on two case studies. Directional analysis of morphological lineaments and old faults show partial coincidence of directions, but also document how basic circular statistical indicators are influenced by bimodal or dispersed distribution. Multisample testing confirms significant differences between orientation of faults and lineaments. Analysis of noise violation offences in Ostrava provides an overview on how to process cyclic temporal data. The time of day is highly concentrated and depends on the day of week. To the contrary, the month and day of the year show uniform distribution.","PeriodicalId":107301,"journal":{"name":"2019 International Conference on Military Technologies (ICMT)","volume":"49 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134142349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
