Geogratis - NTDB Collection

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 map correcting and updating, analysis, modeling, and image processing. The GCDB was initially developed to supplement processing and/or correction of LANDSAT and SPOT data for value added satellite imagery products. Now, through GeoGratis, online access to the GCDB is offered as an efficient and cost effective method of delivery to the end-user.
