Sažetak
Selection of observation sites for fire protection system usually includes a performance of viewshed analysis. Application of GIS analytical capabilities, information and communications technology (ICT) and spatially-oriented data provides the basis of the fire protection system.
In this research, six proposed locations for set up of surveillance cameras within the Zadar County were evaluated according to indicators of visible land cover and the proportion of the visible area relative to the total land area of the Zadar County. The evaluation was performed by analyzing the overlap of the binary viewshed model, type of land cover and layer settlements. Analysis of suitability for proposed location was performed within the project „HOLISTIC“ IPA program of Adriatic Cross-Border Cooperation 2007–2013.
Results indicate that two of the six proposed locations are not suitable for set up of surveillance cameras. On the example of two transmitters, the impact of DEM error on the output results (viewshed model) was analyzed. For the first time on the specific example in Croatia, difference between probable algorithm and standard binary method of determining visibility has been quantified (fig 6 and 7). It can be concluded that the reliability of the viewshed model, or the difference between tested algorithms, depends on geomorphometric features of the terrain on which the analysis takes place.
