Chapter 5: Using charts
5.1 Introduction
RayTech utilizes chart layering technology, which permits you to simultaneously view different types of charts and maps, including navigational
charts, live radar, aerial photographs and weather data.
For full information on installing charts refer to Chapter 2 - Getting Started.
Use your charts safely
CAUTION: RayTech should not be used as a substitute for good
navigational practice nor for official government charts.
Until you are familiar with interpreting the chart display, you should take
every opportunity to compare displayed objects with visual targets, such as
buoys and coastal structures. You should practice harbor and coastal navigation during daylight and in clear weather conditions. RayTech simulator
mode will also help you gain experience.
When connected to a heading data source you can also overlay the radar
image on to the chart.
5.3 Opening a chart
To open a chart for the first time:
1. Click File/Open New Page. The open new page dialog box is
displayed.
5.2 The chart screen
The amount of detail shown varies for different chart types and areas
covered. The scale at which the chart is shown also affects the amount of
detail shown. Cartographic information is also available for objects marked
on the chart. Source details for such objects as structures, lines and open
sea areas are also available. Using the advanced functions described in
Chapter 7 - Using RayTech’s Advanced features, information on the
weather, tides and currents can be overlaid on the charts.
