Mechanisms and Basis of Coding Building Numbers

Mechanism of calculating local coordinate of a building:

  • Local X coordinate: it is calculated by adding 2000 to the delta distance between coordinate (X) at the center of the building and the smaller coordinate (X) of the zip code. The result is approximated to the nearest correct number.
  • Local Y coordinate: it is calculated by adding 6000 to the delta distance between coordinate (Y) at the center of the building and the smaller coordinate (Y) of the zip code. The result is approximated to the nearest correct number.
  • Numbers related to local coordinates refer to the center of the building, but any value inside the building boundaries can be considered correct. Any of these values can be used as the building number, unless they exceed the building's borders.

 

Local (X) coordinate is considered the building number, and the value is approximated to the nearest odd number, in case the number was not odd, (by adding or subtracting 1) to the original value. The numbers of the buildings in such case are odd, ranging from 2000 to 5999. Local (Y) coordinate is considered the additional number of the building.

Local (X) coordinate is considered the number of the building, and the value is approximated to the nearest even number, in case the number was not even, (by adding or subtracting 1) to the original value. The numbers of the buildings in such case are even, ranging from 2000 to 5999. Local (Y) coordinate is considered the additional number of the building.

Local (Y) coordinate is considered the number of the building, and the value is approximated to the nearest odd number, in case the number was not odd, (by adding or subtracting 1) to the original value. The numbers of the buildings in such case are odd, ranging from 6000 to 9999. Local (X) coordinate is considered the additional number of the building.

Local (Y) coordinate is considered the number of the building, and the value is approximated to the nearest even number, in case the number was not even, (by adding or subtracting 1) to the original value. The numbers of the buildings in such case are even, ranging from 6000 to 9999. Local (X) coordinate is considered the additional number of the building.

The oblique angle is measured: if it ranges from 45 to 135, the building is considered fronting the (north/south); otherwise, the building is considered fronting the east/west.

They are classified according to the following:

  • The largest classified (road/street) is given the priority, and the building is coded according to it.
  • If the building is overlooking two equally-classified streets, it is coded according to the longer street.
  • If the building is overlooking two equally-classified and streets with the same length, the coding will depend on front of the building .

If the angle of the building front is 45 (or 135) or its reverse angles, and the streets which the building overlook are equal in length and classification, the building can be correctly considered fronting any of them.
