Web diffusion
The final objective of this work is to share 3D data and models with end-users via the Internet. To achieve this objective effectively it is necessary to select format and software which are free or inexpensive and widely accessible, to avoid the high cost and niche nature of most of the 3D softwares. Finally the open source and ISO standard Virtual Reality Modelling Language (VRML) file format has been chosen. This technology allows manipulation and display of 3D objects, enables object scaling, rotation, translation and modification as well as advanced camera management and the capability to obtain information over 3D features.
Web-based data and models in GeoIT3D will be selected and managed through a layers list where users will be able to find attribute and metadata information.
