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.

    This is structure of a basic definition of two shapes:

    You can also create a GEOJSON from a Shapefile. For more information, please see Creating GeoJSON files.

    GeoJSON Import

    Once the GeoJSON file is ready, user can proceed with import.

    1. In the Map charts geodata screen user needs to click on the Import GeoJSON and select the file.
    2. Click on the imported place definition to edit data or you can proceed to report to create new map.
      Following options are available
      1. Add definition entry (to add new latitude and longitude definitions into the exiting definition)
      2. Export option will export existing definition into file NameOfExistingDefinition.json.
      3. Delete definition will delete existing definition
      4. Back to overview will return user to overview of all available definitions
    3. On the screen of the particular GEO shape definition user can edit following parameters:

      1. Name, 
      2. GeoJSON
      3. Associated drill-down values (multiple parameters can be inserted by using , as an delimiter)
      He can also see the preview of the shape. This enables him to check whether the shape definitions are correct.
