The mapping of protected architectural heritage objects acquiring valuable geoinformation data is relevant today and in the future. The research is based on detection the preferable mapping technique for inspection and capturing the position of small architectural objects in public space, presenting the real geographic/ cartographic information for consumers in appropriate digital environment. The analysis and discussion involve the definition of appropriate technology, implementing goals of the culture strategy in Lithuania, preserving and updating information about cultural monuments, creating the open access to everyone. Applying different techniques, two projects were realized: 1) the mapping and 3D modelling of sculptures in public space – small objects of city park; 2) the mapping of architectural heritage object – field museum, located in open territory with natural topography. Up-to-date mapping/ surveying methodologies as Remote Sensing (RS), Aerial Photogrammetry, Terrestrial Lidar Scanning (TLS), specialized geoinformation systems, UAV-Photogrammetry and classical surveying have been used for providing the spatial products of area topography and 3D models of any architectural objects, opening up cultural values of protected unique objects for the public and allows them to be easily accessed remotely. The analysis of results deals with applicability of TLS technique that provides effectiveness of 3D modelling and UAV-Photogrammetry with high resolution of aerial imaging and modelling solution. Some disadvantages have been highlighted on the use of orthophoto map for Geographic Information Systems (GIS) needs.
