Architectural inventories are the main field for using innovative technology ( remote sensing). The main purpose of using ie. Laser scanning or photogrammetry is to capture all of the important details of structure. Regarding the extents of inventory works, it may only apply to external details, such as facades, supporting structures and surroundings, whilst in terms of advanced inventory, the building's interior is also expected to be surveyed. The interior works are far more difficult due to complex nature of building's plan. In case of older structures, more historic ones, there are many obstructed places and wall bends that make the survey's geometry situation far more difficult. In this study, the LiDAR technology was implemented considering its look at detail and the whole. Laser scanners are capable of measuring with great spatial resolution giving the operator useful information of both structure placement, together with surface details. No other technology is able to conduct architectural surveys no matter what the light conditions are, giving the opportunity to scan remote, dark basements and attics. This the biggest advantage in comparison to classic photogrammetric surveys conducted with cameras that require proper amount of light. Those pros give operators a chance to complete the works in incomparably shorter time with much higher data quality. A final product of such inventory works are special datasets -"pointclouds" that might be further developed in CAD drawings. Contemporary architectural products combine those CAD outlines into Building Information Models (BIM). What is more, the application of such fast and accurate measuring techniques in service of preserving the cultural heritage sites, endangered by natural disasters or human activity, is worth considering when it comes to possible, unreversable damages. Aforesaid cooperation between industry and university is a perfect match of effectiveness of commercial approach and academic expertise.
