About the CD File and Data Structure File and Data Structure describes the organization of the CD-ROM from a directory perspective. Includes how the data is organized by NTS map sheet and data formats. Data Dictionary section describes the internal structure of the files, such as defining what the fields in a database represents, technical specifications about the database structure, and the metadata. Projections explains what projections were used for the map data. Legend included for another reference for the map units. IMPORTANT! The Digital Surficial Geology was compiled and referenced to Geomatics Canada's National Topographic Data Base (NTDB) at 1:50,000 scale. The topographic data such as the contours, rivers and lakes, are included on this CD-ROM only as a SurView file format for the user's convenience (note: there are no attribute information tagged with the digital topographic base). However, the topographic base is not available as a GIS data set. Click here to obtain more information about purchasing NTDB data.
