Georeferencing: The process by which an element is provided with coordinates within a cartographic or spatial entity where its exact location is known and marked.

Scaling: The process by which an element with its own measurements and volumes is subjected to a correction, of higher or lower measurements and volumes, until the desired result is achieved.

Orient: The process by which an element is framed in space in specific directions and parameters.

Geotechnics: Science that studies the mechanics of soils.

Coordinate: References, endowed with numerical values that mark elements of interest within mapping, referencing or three-dimensional modelling systems.

Datum: Abstract coordinate system with a reference surface (such as geoide, ellipsoid, sea level) that serves to provide known locations to begin surveys and create maps.

GIS: Abbreviation for GeographicalInformationSystem, these are electronic tools integrated in software that facilitate work on geographical data.

Orthomosaic: Product obtained by rectification and visual corrections of geometric distortion applied to a three-dimensional model from which it has been possible to obtain a continuous mosaic that forms a single image.

Surveying: Refers to topographic surveying, in reference to the set of geographic data collection activities, datum-coordinates that can be applied in this process together with their methodologies and the use of specialized tools.

Navigation system: Refers to the satellite geolocation of an element by exchanging signal ranges from any medium on the planet that is located at a point in the lithosphere, hydrosphere or air environment.

Control points: Coordinate points used to orient and scale the three-dimensional model obtained by photogrammetric science.

Target control points: Portable physical elements that can be reused or not, where the coordinates of that point are marked in situ by means of specialized tools.

Natural control points: These are control points that will help to scale and orient the model, but are obtained by taking and giving coordinates to elements that make up the model itself, such as a singularly shaped stone or the vertex of a building.

Noise: These are elements that have not been captured in good conditions due to incorrect field work or are elements that are of no interest in the composition of the model, but appear in the background of the image. These can appear as loose points, protuberances. Deformations…

Contour lines: These are lines that connect locations with the same values within a plane. Among the studies that can be carried out on the photogrammetric model, we can find temperature or altitude.

Histograms: A representation of data in the form of a bar chart that provides a wealth of information about the model.

Laser distance meter: An electronic tool available in various formats, either stand-alone or integrated into other tools, which launches a visible laser beam to measure the distance at which it is being aimed.

Drone: Unmanned aerial device, operated from the ground.

Flight Mission: Set of elements that make up a pre-established automatic flight, such as the route, altitude, number of photographs to be taken, speed or time of completion…
