Cadastral measurement of buildings – the easy way

Manual fieldwork and classical measuring method are no longer the most efficient and
accurate way of spatial data acquisition for cadastral boundaries mapping. Speed,
cost-efficiency, data quality, and quantity, ability to do everything in one go with no need
to revisit the site, ease-of-use, and scalability in terms of applying the same process and
technology to large-scale projects, all of these stand as enormous benefits of drone
mapping to any surveyor. Add to this a whole lot of customizable results and extremely
accurate, visually appealing outputs with more information any professional could ever
want, and the advantages get pretty self-explanatory.

In this project, Metod Gutman did a measurement for the entry of the building in the
cadastre. It is necessary to measure the corners of the building, the position of the roof
(stroke, ridge, slope), the lowest point of the terrain and measure the building inside.
The vast majority of this data could now be obtained using a drone.
Surveying with a drone offers enormous potential to GIS professionals. It is possible to
carry out topographic surveys of the same quality as the highly accurate measurements
collected by traditional methods but in a fraction of the time. This substantially reduces
the cost of a site survey and the workload of specialists in the field. With PPK
geo-tagging, you also save time, as placing numerous GCPs is no longer necessary.
You ultimately deliver your survey results faster and at a lower cost.
