System overview

To provide a framework and operational understanding of WRAP from a user's point of view, we define the system to comprise these functions:

• Databases
• User workspaces (projects)
• Presentation tools
• Calculation tools >>
• Power point presentations >>

System overview

Databases

Several databases are required to support WRAP and provide maximum utilisation of the advanced features of the system. The data comprises basically two different categories:

1. Geographical data. Terrain data consists of ground classification (clutter), elevation data and vector data, e.g. roads or coast lines. Scanned image maps, satellite images and aerial images may be used. WRAP can also make use of population databases for calculation of total covered or percentage covered population.
2. Station and equipment characteristics. Station data are locations, frequencies, antenna directions and other installation dependent characteristics of a station. The equipment characteristics comprise information about the different transmitter, receiver, and antenna equipment utilized by the stations. The station database used by WRAP is referred to as WRAP dB.

User workspace

The user workspaces, i.e. the project files or documents, contain excerpts from WRAP dB, usually a limited portion of data which is currently of interest. The project also contains all results which the user has calculated and all the settings and preferences. As the name implies, the project or the document is just a local work space, which means that the user can edit stations and make any experiments with the input data without affecting the central database. All calculations are associated with the current project and, once they are finished, they will be saved along with the rest of the workspace. The project file is treated as any document and may be copied or distributed among other users, i.e. the contents can be saved using a different file name, be printed etc. The file extension will be *.wpr ( WRAP pr oject) or *.wpe ( WRAP project with Equipment data).

Presentation tools

The Map Viewer is the entity within WRAP which is responsible for all presentations using geographical data, either as a Profile Viewer, a common 2-D map or, as full 3-D map. The Map Viewer will work with any combination of geographical data, results and scanned images. A large number of user definable colours, settings and options are included in all three views.
