| APPLICATION | GIS Customization / Web Mapping |
CCRS recently completed and published the Ground Control DataBase, a collection of over 37000 geo-corrected, high-accuracy aerial photo imagettes of the Canadian landmass. Tom Kralidis was the principle lead in developing the output dataset, and chip web browse interface mechanism.
The CEONet system was chosen as the web-based infrastructure to provide nation-wide user-level access and search/browse functionality to the dataset.
Initial response / feedback from the Geomatics community was concern of not having full dataset access capability of the dataset within isolated GIS environments.
A hybrid GIS/Web system will be developed to provide the end-user with a GIS environment displaying the Ground Control DataBase as elevation points, linking to a web environment to show corresponding aerial photo chip imagery for orientation. Aerial photos displaying GCP information aid in numerous GIS operational environments involving geo-referencing, map updating, and image registration.
Automation, interfacing, and conversion tools will aid in the development of effective data access methods.
The FDGC 2.0 metadata standard will be implemented on housing data to maintain a common framework and aid data cataloguing / access.
Data obtained may contain invalid geo-position information. Fallbacks are available from other derived data sources.
There may always be hardware/software component failures, which may affect the performance and efficiency of the system. Fallbacks are available by obtaining new hardware components/restoring files from backups.
