The technical office shall carry out topographic surveys, in order to record in detail the geometrical properties of the plots. The use of modern measuring instruments shall be applied in order to achieve the maximum capture accuracy.

In the topographical diagram all the elements of the property are declared (ownership status, coordinates, dimensions, areas, geographic location, building terms).

Composing a topographic diagram on a property is useful for:

| contract writing 

| threshold corrections

| Property Regime Control 

| spatial changes in the National Cadastre

| ownership delimitation

| dependency on trigonometric coordinate system (EGA ’87)

| Integrity - constructibility check
