3D representation of objects and territories has been an everyday reality almost for everything. Software such as Google Earth and Google Maps has spatially enabled almost every aspect of our lives thus enhancing the way we deal with and use information. In this paper a low cost and efficient way of displaying dynamic 3D information on basemaps that can be used in any case including displaying Cadastral Information is proposed. Furthermore a mechanism for dynamically updating Digital Terrain Models which are used in order to display the 3D information is also proposed. The efficiency of the technique is demonstrated with an actual example developed in C++, .NET and OpenGL. Various improvements have been tested with the use of Assembly language and SSE2 instructions, for common and repeated tasks such as calculation of elevation, Point in Polygon functions etc. Cadastral information has potentially many users since it is of great value for many activities. Cadastre is the base for any land reform, which means that access to Cadastral data should be provided to both professionals and citizens. Data management and representation of 3D information is a demanding process that usually has a great cost and is difficult to implement and maintain. In the era of Information Technology, the CLOUD has come to offer powerful infrastructures with low cost leading many public and private companies to adapt this concept. This paper describes an easy implemented solution that can use the CLOUD platform to massively provide 3D visualization for the scope of the Cadastre.
