From technological point of view BIM includes a set of procedures for spatial modeling of designed building structures to support modern design, construction and operation techniques from the early stage of life of a new object. The basis for BIM design is shaping the three-dimensional body of the object, including its technical equipment, supported by its spatial visualization. Thanks to it, the design process of the structure is complemented by currently created views that can be used in the decision-making process and conflict situations. Observation of the project in the background of its surroundings allows also assessing the feasibility of its implementation in relation to objects related to the place of its final location. The method of such observation is currently referred to as a virtual or augmented reality (VR or AR) and is based on 3D visualization techniques. In order to meet the requirements of spatial visualization, the way the map for design purposes is made must ensure its three-dimensional location in the field. Thanks to this, also invisible terrain content will be visible in the VR/AR mode, which should be conducive to the detection of spatial collisions and the optimal location of new networks and devices in the increasingly complex underground reality. It will also be possible to detect map errors as well as the newly designed object as soon as possible. This needs not only to see not only the map or design in real environment, but all mentioned components have to reference to each other. Such approach is sometimes called Extended or Mixed Reality (XR or MR). The subject of this publication is the introduction to the issue of this aspect of XR/MR applications and the indication of directions of 3D mapping development in accordance with the requirements for the form and content of the map for design purposes.
