Serviciul Localizare Imobile – este un serviciu gratuit prin intermediul caruia puteti identifica puncte de interes de pe teritoriul Romaniei si nu numai, utilizand coordonatele plane sistem Stereografic 1970 sau Stereografic 1930 sau coordonate geografice (latitudine si longitudine) sistem WGS84 (coordonate afisate de “GPSuri”).

After identifying the coordinate system we must identify the coordinates of an interest point. These coordinates exists in a chart on the emplacement and boundary plan. Coordinates are a pair of numbers (abscissa and ordinate point) towards the cartesian coordinate system (Stereographic 1970 or Stereographic 1930). For example in the table below are centralized types of coordinates of coordinate systems used in Romania.
| Vertical Axis | Horizontal Axis | Can be located | |||
| COORDINATE SYSTEM | Stereographic 1970 | Name | X | Y | YES |

Note: Coordinates in the above table represent the approximate center of the roundabout from the University Square in Bucharest.
Suppose we want to visualize the point that has the following coordinates in Stereo'70 system (N (X) = 326,792.080, E (Y) = 587892.944). First, we will choose the coordinate system, in this case Stereo'70, and enter the point coordinates. Afterwards, we will press the button "calculate" and automatically the point position it can be visualized on the map.
Suppose we want to visualize the point that has the following coordinates in Stereo'30 system (N (Y) = 337,856.100, E (X) = 556,666.937. First, we will choose the coordinate system, in this case Stereo'30, and enter the point coordinates. Afterwards, we will press the button "calculate" and automatically the point position it can be visualized on the map.
How does it work?
Through this service you can visualize some points of interest, points for which are known plane coordinates (Stereographic 1970; Stereographic 1930) or geographic (latitude and longitude on the WGS84 ellipsoid). After specifying the coordinate system and the actual coordinates, press „calculate” button; the point will be represented on the map (Google Maps). Normally Google Maps works with geographical coordinates: latitude and longitude referenced to WGS84 ellipsoid. In the situation when the user chooses the option coordinate plane: Stereographic 1970 (officially representing the coordinate system of Romania) or Stereographic 1930 (coordinate system is used in Bucharest until 2012) the program converts these coordinates in WGS84 geographic coordinates through a 7 parameters transformation.
What can I use it for?
Assume that you want to buy a property (land) and do not know where it is exactly located, or you want to check its location. Property Localization allows identification and visualization of boundary points (points that define the boundary of the property).If you own a copy of the emplacement and boundary plan of the property (part of the cadastral documentation of the real estate) you can find the boundary points over there.
How do I proceed ?
First you need to identify the coordinate system in which the cadastral documentation it was executed. This is shown on the emplacement and boundary plan, and there are three possibilities depending on the year when the documentation it was made:
• LOCAL coordinate system – if documentation was executed in a local coordinate system (this usually happens only when approved documentation is prior to 2007) the property CAN NOT BE IDENTIFIED. By definition the local coordinate system is has an arbitrary datum and so the cadastral boundary coordinates CAN NOT BE CONVERTED in WGS84 coordinates. In this case WE RECOMMEND you to not buy the property. Local coordinate system does not guarantee the site; basically you cannot be sure of its location. You should contact the company or an authorized person to prepare the cadastral documentation to update the cadastral boundary coordinates (practically OCPI will approve the cadastral boundary in the national projection system or Stereographic 1970).
• Stereographic 1930 coordinate system – this coordinate system was used only on the cadastral documentation in Bucharest and only until May 2012. Sometimes is called the Bucharest local system or Stereo 30 system or Stereo 30 local Bucharest.
• Stereographic 1970 coordinate system – this is the national projection system of Romania. It is also sometimes called Stereo 70 or Stereo 1970.
