Summary
Abstract: The Ground Control Database (GCDB) is a collection of geo-corrected aerial
photo images (or chips) developed for the GIS and remote sensing community. The
database provides accurate and useful information obtained from corrected
aerial photos. This database can be used by the end-user as a fundamental data
source for correction and validation of satellite, vector and raster data, as
well as for ... View entire text

Quality These products were geo-corrected without the use of detailed elevation data or
DEM, but were corrected to a constant elevation which was known for the centre
of the image. Position errors in off-centre areas are likely to occur in areas
of high relief. As a result, the point of highest accuracy for each chip is
the centre line/pixel XYZ value.1 aerial photo completed for each 1:50000 NTS
