need of a standardized methodology access for the construction of a feature catalogue of
spatial data to support an effective navigation for emergency vehicles. In that way the
hypothesis proposed in this thesis are confirmed. The methods of creating a feature catalogue
of digital navigation bases as it is defined in the international standard ISO 19110:2005
proved to be adequate. Feature types and feature attributes in the feature catalogue are partly
summarized due to the international standard ISO 14825:2004. The others are according to
their identified needs user – defined. A so planned feature catalogue contributes to a
promoted distribution, sharing and repeated use of special data. So a better understanding of
the content and data meaning is guaranteed and it also enables a united classification, the use
and the way of presenting the feature types. The prices for data recording decrease and at the
same time the definition and drawing up of the data set is simplified.
The creation of a feature catalogue is based on the study of needs and demands of emergency
vehicles on their way to the scene of the accident. There are considered all main friction
factors in traffic (traffic density and a fluent flow of traffic, obstacles etc.) Feature types and
their attributes are taken into consideration specifically that enable an effective navigation of
emergency vehicles: category and type of the road, direction signs, appropriate (3D)
presentation of the real world, administrative areas, buildings and parts of them, influent
accident areas, sources of hazardous substances etc. At this point I found out that a part of
project types and their attributes are not included in the data base of official institutions.
Some of them comprise only the local level, methodological and in some way not in
accordance and because of that is the quality of that kind of data usually not adequate. Data
of road conditions (reconstruction works, roadblocks, etc.) are not reported in time by the
road workers to the centres of data recording and distribution. Therefore is the effectiveness
of the navigation in emergency vehicles low. The mentioned examples in my thesis
determinate the optimal routes for emergency vehicles that consider the data of the feature
catalogue, prove of shortening the arrival time to the scene of the accident. The data, by
appropriate graphic or other presentation, present an important support for the navigation in
emergency vehicles especially then when the path is not known, when there are bad weather
conditions, or an unknown area where the accident happened etc. I have to mention the fact
that perfected and and versatile usable navigation instruments and other devices for
