NAVIONICS Electronic Charts
NAVIONICS ELECTRONIC CHARTS
The GEONAV includes a built-in world map that allows
zooming from 4,096 down to 512 NM.
Additional cartographic details relevant to the specific area of
navigation are available by NAVIONICS Seamless Nav-Chart™
cartridges.
When a cartridge is present, a small square will show the area
covered by the chart. Positioning the cursor inside the square
and then decreasing the range with the
ZOOM+
key, the details
of the area covered by the chart will be displayed.
Generally the maximum detail level is obtained in the port
plans and can reach 1/8 nautical mile (the smallest point on
screen is equivalent to 1 m approx.) depending on cartridge
type and coverage.
