Example theme maps

Each of the following theme maps was created with SurView (included on this CD-ROM in \CANADA\SURVIEW), using the ROX*.SHP 'shape' files. Each map represents a different 'view' of the Geological Map of Canada database:

• UN (unit code)
• ER (age at the era level)
• PE (age at the period level)
• RC (rock category)
• RS (rock category, subdivided)
• RA (rock category, broken down by era or subera)
• RS (rock category - detailed area)
