After obtaining the physical data either by control points, images or both cases, the data must be subjected to various processes to be able to give value, being able to perform thanks to these coordinates through its implementation in various programs, various actions of georeferencing and shaping of the results in 2D and 3D resources that you want to create with their support.

Computer aided drafting is one of the main uses of coordinates, to create two- dimensional documentation of the captured terrain, very useful for planimetry and mapping.

Technological progress means that thanks to various programmes and disciplines such as photogrammetry, these coordinates can be implemented or obtained in different ways. It is possible to georeference images that have been taken without any value, or to give geographic value to various points that may make up the point cloud of a three- dimensional photogrammetric resource, among other options…

We can find various photogrammetry programmes that allow us to provide the images with coordinates, this tool is used by a large number of professional programmes such as Pix4D, Metashape or Reality Capture, by means of which the implicit coordinates can be included in the photographs themselves from the first moment of processing, as is the case of photographs captured by drone missions.

It is possible, using a simple tool similar to a notepad with blank tables, to insert the values annotated or digitally documented in the terrain data acquisition. This process is applicable to both photographs and a selection of points.

In the case of having inserted already georeferenced photographs in the programme, the programme will start to work with these values, scaling the model according to the proportions that the control points mark between them in terms of distance. On the contrary, if any type of process has been carried out and the coordinates are manually inserted in the programme, the processes must be carried out again to adjust the values according to the adjustment provided by the coordinates, obtaining a scaled and oriented three-dimensional model.
