5. Reorganizing your data

The program will sort on any column when you double click on the column header. Double clicking again will reverse

the sort. For more complex sorts, check out File>Sort File. You can also use File>Combine Files or File>Split

File to make up different groupings.

After sorting the data, you can purge or merge duplicates with Edit>Find Duplicates. It will scan the file and show

which waypoints have other waypoints very close by.

6. Changing how the numbers are displayed

There are many different ways to describe Latitude and Longitude. They can be in degrees only, in degrees and minutes

or degrees, minutes and seconds. Most GPSs default to degrees and minutes. The program has a Display>Number

Formatting screen that lets you pick how your numbers will be displayed. Even though you pick one of these forms

for display, the program stores the information internally in a standard form. You can enter data in any of the other

forms and it will be accepted and converted to the standard form.

Range can be in feet, statute miles, nautical miles, or kilometers. If the numbering or distance formats are not the way

you want them, change them. If the range is set for feet and the number is too big to display, the program will show –1.

You can also set the length of the GPS Name field here.

7. Showing the waypoints on a chart

Once you have some waypoints in the file, you can display them on a chart. Use Display> Display on Chart,

Display on NOAA chart, or Display on Google Earth. Charts can either be a simple chart created by the

program, a raster digitized NOAA chart, or Google Earth. The program will scale a simple chart big enough to show all

the waypoints on the screen or will show a NOAA chart at a nominal zoom level. Google Earth will display a zoom

level sufficient to show all your points.

Use the Pan and Zoom capabilities to make the chart show just the area you want to see. There are several ways to both

pan and zoom. To pan, you can use the cursor control keys to move the viewpoint up, down, left, right for the simple

chart or the scroll bars for the NOAA chart. If your keyboard has a number keypad, you can use the peripheral keys (all

but 5 and 0) to pan in 8 different directions. You can also make where you click the cursor the center of the chart or pick

a specific waypoint to center on. Try the selections on the Chart Operations Menu to see what are available. When

working from a large-scale chart, Select Area is one of the more useful tools in that, you can pick a specific smaller

area and, in effect, pan and zoom at the same time. Another tool is Identify Waypoint that, when clicked near the

waypoint, will show some of the waypoint's data at the bottom of the screen. What it shows is based on the spreadsheet

display choice.

Select Chart Operations>Coastline and remove the coastline from the simple chart. You can also use Chart

Operations>Charting Options to select or deselect what is shown on the chart such as Lat/Lon lines, Range/Bearing

lines, or Loran lines.

8. Making Maps

For our (Andren Software's) convenience, we make the distinction that charts are for the moment and maps are

permanent even though they may show the same thing. The difference is that you will save maps on the disk so they will

be the same every time you print your book. A good practice is to create (with Map>Create Map) one overall map

with the waypoints as dots to see the overall reef layouts. Then make a sequence of maps with the waypoints as numbers

or names that slightly overlap and show all the area in a scale of perhaps 10 minutes on a side. Finally, make maps that

detail the concentrated reef areas on a scale of 1 to 2 minutes on a side. These might be even more overlapped to avoid

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 129 130
