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.
