Cartography

The GPSMAP 3005C has a built-in worldwide database, with more detailed
coverage available through the use of optional BlueChart or MapSource data.
The unit shows cartography as long as there is chart information available for the
selected range.
The GPSMAP 3005C accepts preprogrammed data cards and is compatible with
the latest BlueChart g2 series marine cartography, which features integrated
®
mapping, 2-D or 3-D map perspective, tide and current data, improved IALA
symbols, navaids, marinas, boat ramps, roads, and more.
Map coverage conforms to the following conditions:
• Cartography appears when the selected zoom range is covered by either the
internal database, BlueChart, or BlueChart g2 data.
• When the selected zoom range is covered by both the internal database and
BlueChart or BlueChart g2 data, the cartography with the best resolution
appears.
• When the selected zoom range exceeds the resolution of the data in use,
overzoom cartography appears and an overzoom warning appears below
the range.
