Explanation of terms
Object type*:
admin (level 0-7) This layer depicts the administrative and political boundaries of the country in question. Level “0” corresponds to the country as a whole, with an increasing level of detail for each successive level (e.g., 2, 3 and so on).
postal (1-7 digits) This layer depicts the postcode divisions of the country in question. “1” refers to one-digit postcodes, “2” to two-digit postcodes, and so on. The higher the number, the more detailed the depiction of the postcodes.
TT This layer is based on TomTom cartography.
Off. code**:
This layer contains labels featuring official regional codes – for example, the official designators of postcodes used by the national postal organization.
Nat. lang.***:
In addition to ASCII-based labels, this layer contains labels in the language (and associated special characters) of the country in question. For some countries local labels are not properly
