Fig. 14.6 Screenshot montage of the GE interface showing: (a) The data and photo of an
observation point ( lower right ), (b) a borehole log from the borehole database ( upper left ), (c)a
geological map draped on the DTM, and (d) the boundary of the mapping areas ( dark lines ). These
data together enable one to easily overview the spatial relations between the geological formations
software, which is capable to read the KML format, is suitable for this purpose. The
free tool was selected for the visualization, because an unlimited number of users
can access the files after creation and interpretation of the data-packages. Further-
more, the visual representation of the geological data in GE is enhanced with built-
in background of satellite images, digital terrain models and a wide range of
arbitrarily selectable themes. The following maps were displayed for geo-scientific
purpose along with the observational database:
• Geological maps covered and uncovered by Quaternary sediments
• Geochemical maps
• Topographic maps
• Geophysical (e.g.: Bouguer anomaly) maps
• Geological maps for tourists
• Hydro-geological maps
The geo-scientific approach of the visualization of geological data brings up the
necessity to visualize not only the observations, but, for example, the boreholes in a
given area too (Fig. 14.6 ). The borehole database as well as the observation
database can be transcribed in KML format. For the querying of a database,
different from the observations, a Visual Basic script was programmed. With the
