A topographic diagram is a comprehensive topographic study, on which are imprinted with the required accuracy the following:

  • Geometrical features, such as shape and size of the area
  • Any objects that are within the measured area
  • The coordinates of the property, whether in an independent (in arbitrarily certain system), or in a dependent HGRS ’87 ( Hellenic Geodetic Reference System 1987)


The topographic diagrams have applications mainly in:

  • Road and transport studies projects
  • Studies of building projects
  • Cadastre
  • GIS systems (Geographic Information Systems)
  • Studies of hydraulic projects (water supply, sewage disposal, port projects, dams, etc.).


Factors for composing a topographic diagram

The factors which are taken into account in composing a topographic diagram are:

  • Its use
  • The study area of the property
  • The requirements of the use for which the studies are intended.

Topographic diagram data

In the Topographic diagram are depicted:

  • Full mapping of the area that is under measurement and of the adjacent plots in the wider area and definition of boundaries
  • Table of coordinates and dimensions of the property
  • Applications of the urban planning legislation and in some cases of legal science
  • Fragment of a street plan or draft, but also area map sheets.


In IONIKI, we undertake the composition of topographic diagrams based on the improvement of processes from the on-site measurement collection, up to the implementation of the correctly produced technical department, defining secure, according to the appropriate decrees and the definition of the contract, transactions of the property owner.
