A topographical diagram is a comprehensive topographical study that accurately depicts the following:

1. Geometric characteristics, such as the shape and size of the area.

2. Any objects present within the measured space.

3. The coordinates of the property, either in an independent (arbitrarily defined system) or in a dependent HGRS ’87 (Hellenic Geodetic Reference System 1987)

Topographical diagrams are primarily used in road studies and transportation projects, building project studies, GIS systems (Geographic Information Systems), and studies of hydraulic projects (water supply, sewage, port projects, dams, etc.).

Factors for Preparing a Topographical Diagram

The factors considered for preparing a topographical diagram include:

(a) The use of the topographical diagram.

(b) The study area of the property.

(c) The requirements of the intended use for the study.

Elements of a Topographical Diagram

The topographical diagram includes:

– A complete depiction of the area being measured, as well as the adjacent properties in the broader area, and the definition of boundaries.

– A table of coordinates and dimensions of the property.

– Applications of urban planning legislation and, in some cases, legal science.

– An excerpt of the urban planning scheme or a travel sketch, along with maps of the area.

At ΙΩΝΙΚΗ Engineering, we undertake the preparation of topographical studies based on the improvement of processes from field measurement collection to the implementation of the correctly produced technical section, determining safe agreements with the relevant decrees and the definition of contracts regarding the transactions of the property owner.
