Services of Geographic Information System – GIS of the Post of Serbia

The records of the address register and the legality of facilities are not within the competence of the Post, which is why the Post does not have information of this kind. Since the delivery of items at the address is done regardless of whether the building is legalized or not, we have mapped all the facilities in the areas for which the Post owns high-quality raster substrates. The quality of data is such that they are “field data”, i.e. all those data available to the postman on delivery.

The Post is not able to provide information on street direction, number of lanes, street connection, or any additional information related to traffic signaling.

In addition to the spatial position of the street, the Post only provides information about the street code and name.

Given that there is official street codebook only for the city of Belgrade, the Post has established its own street codebook which includes the official codes of the city of Belgrade, as well as the Post’s codes of all other streets in Serbia, coded according to the methodology of the official codes of Belgrade streets.

According to the data of the Post, over 30% of streets and roads in Serbia have not been named. The Post named the streets that do not have their official name, according to the information of the postmen, as the locals call a certain street (the way to Mlin, the Đukić neighbourhood, the road between villages of Orašje and Cernica...).

The Post marked all the streets with a status (official or internal) that unambiguously indicates the origin of the code and the street name.

The Post is regularly monitoring the official gazettes of local self-governments responsible for naming streets and squares. When a local self-government publishes new street names in official gazettes, the Post begins to apply these new names and edits them in its database. As soon as a new facility is built and the owner hangs the number or receives the first postal item (for example, electricity bill with the address indicated), the postman reports the facility and the number of households in it. If it happens that the Republic Geodetic Authority, in charge of records of the address register, performs numbering of buildings in some area, but no household begins to apply new numbers (no number on the building, no change of the address on the bills they receive), the postman has no insight that there was a re-numbering of buildings. In this case, the Post’s data are different from the official ones and they represent “field data”. When citizens begin to apply new numbers, these numbers are also applied in the Post.

The service offers various spatial analyses of the Post’s spatial data and/or spatial data provided by users, which have an alphanumeric output (list of addresses, PAKs, etc.).

For example, a legal entity that uses the address database of the Post opens a new branch and wants to notify its users in the area around the branch about it. The legal entity submits the desired area to the Post (polygon drawn in Google Earth), and the Post, by a spatial inquiry, determines the list of PAKs that belong to the selected area. Since it uses the Post’s address database, information about PAK is related to each user of the legal entity. Based on the received PAK list from the Post, it is possible to select users from the desired area in a simple way.
