Geography

DIVA Geography connects grid data (maps) and/or vector data (GIS data) with objects from DIVA that are geography-related, like stops, route sections or route options.

The main purpose of this application is to use and edit GIS data, e.g. the ability to route on networks by Navteq or TeleAtlas.

DIVA Geo provides the foundation for the journey planner (EFA). GIS data is maintained in DIVA Geo using a workspace, where the main parts are the map display, the layer assistant (top right in the picture) and the data tables.

The layer assistant is ordered hierarchically: each point that is listed in the workspace represents a layer. The order of the list in the layer assistant, which can be changed at any time, corresponds directly to the display on the map. When 'edit data' is activated, the individual layers can be changed when working in the map display or in the tabular listing of a layer's data.

Layers are set by the selected GIS network (e.g. Navteq or TeleAtlas), however other individual GIS layers can also be integrated. Individual layers and data in DIVA can be used and edited in others applications through use of an export, which uses formats that can be used with all standard GIS applications (MIF/MID).

By displaying or hiding various layers on the map (filtering the tabular data), an overview can be maintained while editing.

Using the edit function, contents that were not yet part of the existing GIS data can be added. This data can be areas (parks, large buildings, etc.), points (single house addresses, etc.) or routes (streets, paths, etc.).

Every street on the map can be assigned specific attributes.

These are

Traffic permitted (pedestrians, cyclists, motorized vehicles, etc.) in both directions
Name
Street classification (highway, regional road, local road, footpath, rail tracks, etc)
Speed
Additional cycle and footpath attributes (cycle path on shoulder, etc.)

With DIVA Geo places of interest (POI) can be set and allocated to the above point and area objects. In a second step, POIs are connected to the integrated route network by links. POIs can be important buildings (hospitals, government buildings, hotels, etc.), parks or attractions (bridges, monuments, etc.). POIs also help with orientation on the map and can be selected as origins or destination in EFA.

Another feature in DivaGeo applies to the referencing of stops and route sections, which are both supported by an automatic algorithm. In this way DIVA data are connected to the GIS data.
