GiMoDig geospatial service demo
This GiMoDig GUI (Graphical User Interface) demo shows different map applications for end users in different map usage situations in two different platforms: PDA and laptop. The different applications are here called use cases, which are based on user scenarios. By active personalisation of the GiMoDig GUI the user may change the user preferences of the use cases, e.g. time of the day, season and user's age group. The application applies the preferences and adapts the map in real-time. Adaption includes generalisation of the map features while zooming, like simplification and smoothing of the roads.
Sample use cases
Outdoors: A hiker in a national park
Real-time generalisation is needed for showing the topographic data at different
scales suitable for small screen. The map is used for planning the route or
navigating in detail. The outdoors maps are adapted according to the season,
given as a user context. Also integrating of different datasets needs real time
generalisation e.g. for selection of Points of interest (PoIs) data depending on
the context parameters. The test area for this use case was the Nuuksio National
Park in southern Finland.
Cycling: A cyclist at Danish-German border
The use case demonstrates especially the cross-border aspect.
This includes data harmonisation according to the GiMoDig Global Schema. Feature
selection operation is also included.
The test area for this use case is the boarder area of Denmark and Germany.
By changing the preferences for "Time" the maps can be adapted according to day/night.
Emergency: A fire at the University of Hannover
The use case demonstrates how a multiple representation database (MRDB) approach can be applied for information
drilling capability, i.e. zooming from a smaller scale into a more detailed representation of map objects. The use case also
includes so-called Mark-Your-Place functionality. According to the user scenario a
guard is able to mark in real-time on a PDA a fire symbol at a place where he
detects a fire. This information is further transmitted into a database,
which can be controlled from e.g. an emergency central.
The test area for this use case is Hanover city area.
