Geo Regions are used on maps to highlight certain part. Geo Region can be for example country, state or district. By using association between data set and geo regions, it is possible to display information on a map in a form a shape.

Each GEO region is a shape defined by three or usually more points specified by latitude and longitude coordinantes. Standardized GeoJSON format is supported to simplify importing these definitions. Name of region or associated drill-down values can be used to match drill-down members in the report view. You can associate more drill-down values to single GEO region definition. Upper and lower case are distinguished (eg. Canada, canada, CAN are different values).

Following parameters are manageable for GEO regions:

  • Definition name
  • Region parameters: Name, GeoJSON coordinantes, Associated drill-down values

GeoJSON preparation

BellaDati is using standard GeoJSON specification. Therefore it is easy to prepare your own GeoJSONs or use predefined GeoJSONs from another source. Each GeoJSON contains number of definitions, one for each region (country, state etc.). Each definition consists of several parts:

  • shape definition - three or usually more points specified by latitude and longitude coordinantes
  • name - name of the definition, for example name of country. This name can be used for mapping.
  • associated with drill down members (names) - additional names or codes which can be used for mapping. They are optional.
