The National Institute for Colonization and Agrarian Reform published Execution Standard No. 2 in Brasilia yesterday (19/02), authorizing the use of drones for georeferencing rural properties in Brazil. The standard was drawn up following the delivery of a technical report attesting to the quality of the cartographic products produced using aerophotogrammetry by Unmanned Aerial Vehicles (UAVs).
The official announcement of the publication of the Technical Standard took place today, February 20, during the Cadastre and Georeferencing in Land Administration workshop. This event will take place on the 20th and 21st, and will be attended by officials from the municipality, as well as representatives from the Inter-American Network for Cadastre and Property Registration, the Permanent Committee on Cadastre in Ibero-America (CPCI) and the Organization of American States (OAS).
The approval of the use of drones in the georeferencing of rural properties came after pilot projects were carried out by Incra employees using the Echar 20C HA and Nauru 500B HA drones, both developed and manufactured by the Brazilian company xmobots®. The equipment, equipped with an HA (High Accuracy RTK) system, enables photographic products to be obtained with positional accuracy within the standards required by INCRA.
In the document published this week, the municipality establishes the guidelines for assessing the absolute positional accuracy generated by the images obtained with the drones, such as the use of check/verification points, a statistical test that proves the planimetric positional discrepancies at a 95% confidence level (using the Shapiro-Wilk method), among others.
For Giovani Amianti, president of xmobots®, the publication of the standard is a milestone for the drone sector and opens up a new range of application possibilities for remotely piloted aircraft. He emphasizes that, in addition to proving the accuracy of the products generated, UAVs have also optimized the work of the civil servants conducting the tests, as Incra itself described in a published on the agency's website in November 2017.
