Sažetak
The content of vector cadastral map has prescribed structure. Easements are in a separate vector map layer since 2009. The number of easements has been significantly growing in recent years, and it has turned out that the way of displaying of easements in vector maps is not sufficient. There are some issues, e.g. overlapping line and area objects, lack of transparency and lack of connection between the map and the file of descriptive information. The vector maps are accessible to citizens through web portals. Vector maps are originally GIS maps, which means that if they are put on web without any change, the displaying of easements will transmit limited amount of information to the user. The main purpose of this article is to present a solution for displaying of easements through web portal. According to our solution, easement is displayed differently in vector maps and at web portal. Graphical interface of web portals provides higher variability of means and methods of cartographic expression. In order to make displaying of easements through web portal closer to non-professional public, interactive means are used, e.g. colour line symbols, colour area symbols (also with possibility to switch objects on or off), mouse-over techniques for adding textual information and hyperlinks. Our proposal requires some changes in the structure of vector cadastral map, specifically it is necessary to add new attribute for objects in layer of easements. These amendments are essentially negligible in comparison to the effect of displaying of easements through web portal.
