This paper is focused on the presentation of the data which were obtained by Terrestrial Laser Scanning from the Maya center of Nakum, located in north-eastern part of Guatemala. The ruins of Nakum and its surroundings are covered by low and high vegetation which makes it difficult to analyze all surface features and modifications by aerial photography. One of the goal was merging 3D data with information from archaeological excavation and creating database. Point Cloud from Terrestrial Laser Scanning (TLS) was classified and Digital Elevation Model (DEM) with vegetation class was build. It allows us to conduct a very detailed analyze of area and its structures. Those data were integrated and compared to ESRI raster from examined area. The second way of use TLS data was to create interactive 3D map, which is based on triangulated point cloud and contains all digitalized tunnels, excavation unites with georeference, 3D models, photos, drawings and other important research data. It builds accurate database for the inventory and spatial planning, taking into account terrain shape, architectural objects and vegetation density. These data were combined with GIS and free-ware game engine software to create a database with easy open access, interactive publishing, and to build various interactive simulations in real time (flood, sun). Most of used software were open source (Meshlab, Blender, Unreal Engine) or accessible for research purposes (Arcgis).
