Cadastral Validation. Planimetric Survey in Santa Brígida

At Digital Fiber Planners, we know that having accurate technical information can make a difference in any cadastral or urban planning process. That's why today we want to share one of our recent projects: a planimetric survey carried out on an urban parcel located on Calle Juan Río, Santa Brígida, in the province of Las Palmas.

This work was requested by the owner after detecting discrepancies between the area registered in the Cadastre and the area reflected in the property deeds. The objective was to obtain an updated and georeferenced technical database that would serve to correct potential administrative errors.

Description of the Environment and the parcel

The plot has a regular shape, urban use, and a very gentle slope. It is mostly enclosed by walls and features a utility pole with overhead wiring that partially extends over the northern boundary. The environment is predominantly urban, and no unlawful occupations were observed at the time of the survey.

Precise Methodology with GNSS Technology

The survey was conducted on June 13, 2025, using a Trimble R12i GPS receiver in RTK mode, ensuring an accuracy of less than 2 cm. We connected to the REGCAN95/UTM reference system, Huso 28N, via the permanent station of the University of Las Palmas de Gran Canaria.

The work phases included:

• Preliminary inspection of the land.

• Real-time GNSS data collection.

• Processing and comparison with official cadastral geometry.

• Graphical validation of the generated GML file.

• Detailed calculation of the actual surface area.

Results of the Survey

The actual measured area of the plot was 339.61 m², while the registered cadastral graphic area was 329 m², reflecting a difference of +10.61 m². This variation was duly represented in a georeferenced topographic plan and graphically validated.

An additional finding was the slight coincidence of a strip of land with public domain according to the Cadastre, which was identified as a cadastral error already corrected in the final geographical delimitation.

Technical Conclusions

• The difference in surface area detected may justify a registry or cadastral modification.

• The validated GML file and the topographic plan will serve as technical support in any administrative procedure.

• The physical correspondence between the visible limits and the surveyed GNSS points is confirmed.

Why is a planimetric survey important?

This type of studies allows:

• Correct errors in official records.

• Avoid boundary disputes or legal problems.

• Have a precise basis for urban planning works or procedures.
