GML file and georeferencing for the Spanish Cadastre

Do you want to know how land surveyors can help you update your parcels in the Cadastre (Catastro, Spain’s land and property register for tax purposes)? Here we explain it all, starting with what a GML file is and what georeferencing means.

What is a GML file and what is georeferencing

First of all, it is important to understand what a GML file (the georeferenced parcel format the Cadastre and the Land Registry require) is and how georeferencing works. A GML plan is a file that contains geographic and urban information, such as parcels, buildings, streets and so on. Georeferencing, on the other hand, consists of assigning geographic coordinates to the elements of the plan, so that they can be located precisely in space.

The surveyor’s role in a cadastral update

Land surveyors are the experts responsible for taking precise measurements and preparing the graphic validation reports that help update cadastral parcels. This is essential to guarantee that the cadastral information is up to date and accurate. The graphic validation report also makes it possible to detect possible errors or discrepancies in the cadastral information.

In summary

Relying on a land surveyor to prepare a graphic validation report can be crucial to keeping cadastral information up to date and accurate, which is essential for any property transaction or for managing real estate. Rely on the experts at Clotoides to make sure you have the most precise and up-to-date information.
