Topographic survey plan: what it is and when you need it

What it is

A topographic survey plan (τοπογραφικό διάγραμμα) is a scale drawing that shows the boundaries, area and dimensions of a property, the buildings on it and its relation to the roads and neighbouring properties. It is prepared by a qualified engineer after a survey in the field, and it bears the engineer's signature.

What “tied to GGRS87” means

GGRS87 (ΕΓΣΑ87) is the national coordinate system of Greece. When a survey plan is tied to it (εξαρτημένο στο ΕΓΣΑ87), every corner of the property has unique coordinates that can be located again on the ground and compared with the Hellenic Cadastre (Κτηματολόγιο), aerial photographs and state maps. For most purposes today this is essential.

When you will be asked for one

• In notarial deeds signed before a notary, especially for properties outside the approved town plan area (εκτός σχεδίου πόλεως)
• To obtain a building permit (άδεια δόμησης) or a works approval (έγκριση εργασιών)
• To correct the area or the boundaries of a property in the Cadastre
• For subdivisions and mergers of plots, and for setting up horizontal property ownership (σύσταση οριζόντιας ιδιοκτησίας)
• In court cases about boundaries

What to have ready

• Your title deeds and, if you have them, any earlier survey plans
• The KAEK (the 12-digit cadastral code), if the area has been mapped by the Cadastre
• Contact details of someone who can show us the property, if you cannot be there yourself

How the work is done

First we study the documents and the cadastral diagram. In the field we measure the boundaries and the buildings with GNSS and a total station. Back at the office we compare the survey with the title deeds and, if there are discrepancies, we explain them to you before the final plan is drawn up.
