The fortified site Boudy-Hrad is located at southern Bohemia, in the region, where (according to the recent state of art) the early iron-age occupation reveals relative density. It´s located on the hill-top and enclosed within two stone ramparts – outer and inner (which is bigger). In years 1999-2003 the excavation campaigns were realized and recently the time of various analysis takes its place. One of the goals of research in 2003 was 3d scanning of the western part of the inner rempart and complete dense leveling of the inner space of the enclosed area. Obtained sparse data were completed once in analytical programs (ASCII form) and secondly graphically in GeoMedia Professional version 5.2.
While the shape of inner rampart was recontructed in other programs, the task for GeoMedia was to resolve the problem of the relationship of the site and its environment. Since the ramparts were quite damaged by the erosion and human activities during the time, the question of entrances came into light, and their relationship to the communications within the site. So, if the entrances are located at the most easiest access terrain path, or they are determined by the other criteria.

For this task, the GeoMedia GRID was chozen, especially the Corridor Analysis command. Firstly, the DEM (Digital Elevation Model) of the site was created from the vector contour lines and than four of starting points were established, each from the special cardinal point. By the few steps the created paths showed (pict. 4, 5), that the easiest access sides didn´t obviously match with the determiced entrances. Considering this fact, we could conclude, that the spatial structure of the site, especially the location of the major axes and entraces were determined by the other, in all probability cultural or religious aspects. Whith this intepretation corresponds also the fact, that wihtin the site weren´t discovered any of dwelling features.

Finally, the output was realised by the 3d visualisation command (pict. 5.), which advantages come from more natural point of view of the terrain conditions but on the other hand, for the further work with this command, the better stability (within the Microsoft system) and the possibility of at least simple exportable animation would be desirable.
