The products of data collection and data processing that constitute the input data of the platform are the 3D models of the Archaeological Site of Meteora and the two rocks, Modi and Alyssos, as well as the orthoimages of part of the Archaeological Site of Meteora, the dense point clouds of the two rocks and Digital Elevation Models (DEMs). The last three types of metric data are only available to certain categories of users, i.e., geospatial engineers, architects and archaeologists, while the point clouds are only available if requested, upon approval by the system administrator, subject to the terms of a relevant license. The 3D surface model of the Archaeological Site of Meteora with texture generated using the oriented images is shown in Figure 1. The dense point cloud consists of 353,140,592 points, while the surface includes 67,471,539 faces and 34,029,510 vertices. The 3D model of the rock of Modi of OBJ format, is approximately 650 MB and consists of 34 mil. triangles, while the 3D model of Alyssos of OBJ format is 400 MB and consists of 27 mil. triangles.
