iPLOTTER manual

 

Overview

========

 

iPLOTTER is designed for quick and easy passage planning, and then as a real-time navigation aid in conjunction with a GPS

Vectored maps are generated by iPLOTTER, and some low-resolution public-domain maps are supplied, but you can scan any map of your own, copy to your PocketPC platform, and then after calibrating, use it as a moving map within the program.

 

Getting started

===============

Explanations for each menu commands(bold) mentioned in this section are listed below

 

After opening the application for the first time, you will prompted to select

a navigation database.

The default craft speed is set to 5kt. To change this select ‘Tools – Speed setup’

 

A default blank plan called 'Passage1' is initially created

Use 'Edit - New sector' to plan the first sector...

Plan subsequent sectors using 'Edit - New sector' as above.

 

You can now view the plan in simulator mode

Select 'View - ARC', 'View - COMPASS' or 'View - MAP'

then select 'Tools - Start simulator'

The planned passage will be displayed and updated as if you are actually sailing it.

You can change views between MAP, ARC or COMPASS at anytime during the simulation.

 

To display in real-time...

Select 'Tools - Stop Simulation'

Connect a GPS via the serial port

Select 'Tools - Connect to GPS'

Now what you actually sail will be displayed.

 

Now follows a fuller explanation of all menu commands...

 

FILE

====

New Plan

Creates a new blank passage plan and makes it active, while saving the current plan.

Enter a name for the plan, which must not already exist.

 

Open Plan

Lists all previously created plans.

Tap one to make it the active plan.

 

Delete Plan

Lists all previously created plans.

Tap one to delete it. (must not be the active plan)

 

Reverse Plan

Reverses the current plan.

 

Exit

Closes the program while saving the current state.

 

Edit

====


New Sector

Creates a new sector.

 

If the first sector of a plan...

Using uppr/lwr case characters, tap in the name in the 'Depart' box. At the 2nd character a drop down list will display. Add more characters to refine the list and then make a selection.

When a selection is made from list the lat/lon of the waypoint is displayed.

To change your selection, re-open the list by tapping the arrow.

Tap 'OK' to confirm departure point.

The departure/previous waypoint will be displayed.

     

Now continue as above to select the first/next waypoint.

The track (°t) and distance of the sector is now calculated and displayed.

(iPLOTTER calculates rhumb lines for all true tracks)

 

After confirming the 'To' waypoint, a new screen is displayed.

 

After tapping 'OK' the main screen will be updated with the new sector and totals.

 

Delete a sector

Deletes the currently highlighted sector.

 

Insert a Sector

Inserts a new sector after the currently highlighted sector.

 

 

View

====

Next Wpt

Use this command while in ARC, COMPASS or MAP view to force the data display to reference to the next sector. (not available in Simulator mode)

 

Scale out, Scale in (in MAP view only)

These commands will load higher or lower resolution maps accordingly, if the       current position of the simulator or GPS is within the area range.

The maps must have been previously calibrated

out - lower resolution

in - higher resolution

Use the zoom in/zoom out buttons in the menu bar at bottom of display to zoom in and out of the currently loaded map.

 

PLAN

Selects PLAN view.

The columns for each sector display: Crs(t) (true course), Var (magnetic variation), Crs(m) (magnetic course),  Dist (distance nm)

Tap on a sector to display the ‘from’ and ‘to’ waypoints (above sector list)

The plan totals are displayed below the sector list and the active database below that.

     

MAP

Selects MAP view for use with Simulator or GPS input.

Maps that have been calibrated are available to be automatically loaded and displayed. Use the Scale in/out commands to load/unload maps of higher/lower resolution for the same area. When the craft moves out of the coverage of the current loaded map, the next logical map will be loaded. If no user-scanned maps are available, the supplied low-resolution maps are used.

Use the zoom in/out buttons in menu bar to zoom in/out of current map.

When both zoom buttons have a border, the map is displayed in its original scanned resolution. In this state the loading and unloading of adjacent maps that have been calibrated will be seamless. In other zoom settings, the map may be scrolled to center screen before the next map is loaded.

Use the pen to scroll the map around the screen. Use the ‘C’ button in menu bar to centralize the map around current position.

The boat position is depicted by the black cross, the planned track is superimposed on the map.

Turn on/off the lat/long position and Scale windows using the ‘Preferences’ menu command.

 

Data is displayed at the top and bottom of the screen…

(The data is relevant to the current sector waypoint, as the boat moves past the waypoint the data automatically refers to the next sector in the plan)

 

Sector Waypoint and distance to run (nm)

ETE - estimated time en-route to reach the waypoint (mins)

DTK – direct track to sector waypoint from current position (degrees)

XTE – cross track error from planned track (nm)

SOG – speed over the ground (kt)

 

COMPASS

Selects COMPASS view for use with Simulator or GPS input.

This screen displays a compass rose updated to display the current magnetic track of the craft.

The waypoints and planned tracks are displayed relative to the current magnetic track. (Track up)

The white craft symbol depicts the actual position.

Use the zoom buttons to zoom the display in and out.

Sector data is displayed as described in MAP above.

Tap on any symbol in the display to show further information and direct track(m) and distance to the waypoints. Tap button to initiate GOTO function. 

Turn on/off the lat/long position and Scale windows using the ‘Preferences’ menu command.

 

ARC

Selects ARC view for use with Simulator or GPS input

This screen displays a compass arc updated to display the current magnetic track

The waypoints and planned tracks are displayed relative to the current magnetic track. (Track up)

The white craft symbol depicts the actual position.

Use the zoom buttons to zoom the display in and out.

Sector data is displayed as described in MAP above.

Tap on any symbol in the display to show further information and direct track(m) and distance to the waypoint.  Tap button to initiate GOTO function.

Turn on/off the lat/long position and Scale windows using the ‘Preferences’ menu command.

 

     

Utils

=====

 

Preferences

Select preferences as required. These will be saved.

 

Conversions

Select type of conversion required with radio buttons. Now enter the number to convert in relevant box. The conversion will be updated automatically.

 

Sunrise/set

The coordinates edit boxes will be seeded with the destination Lat/long of the current plan, but can be edited if required. Tap ‘Calculate’ button to display the Sunrise/sunset times.

 

Maps

====

Load

Loads a bitmap to the screen for general viewing or calibrating

Use the pen to scroll the map around the screen.

N.B. Once a map has been loaded and calibrated, it will be automatically loaded as required when using the ‘MAP’ function.

 

Edit

Displays a list of all previously calibrated maps

To delete one, select and tap 'Remove from list' button

This will not actually delete the bitmap but simply de-calibrate

It, making it unavailable in the ‘MAP’ function.

 

Calibrate NE

Use this command in conjunction with Load above.

After scrolling the map using the pen so that your proposed NE calibration point is in view, select the 'Calibrate NE' command...now the next tap you make on the screen will be assumed to be the North-East calibration point and a dialog will pop up for you to enter the lat/lon coordinates using degrees and minutes to 3 decimal places

Tap on the 'N' box to change to 'S' for southern hemisphere coordinates

Tap on the 'E' box to change to 'W' for western longitude coordinates

 

Calibrate SW

Use this command in conjunction with Load above.

After scrolling the map using the pen so that your proposed SW calibration point is in view, select the 'Calibrate SW' command...now the next tap you make on the screen will be assumed to be the South-West calibration point and a dialog will pop up for you to enter the lat/lon coordinates using degrees and minutes to 3 decimal places.

Tap on the 'N' box to change to 'S' for southern hemisphere coordinates.

Tap on the 'E' box to change to 'W' for western longitude coordinates.

 

When both NE and SW points have been successfully entered, a window will pop up that will enable you to adjust the calibration to allow for a map that is not referenced to WGS84 datum. Enter the differences of latitude and longitude (usually mentioned in map notes if applies), or zero if no adjustment required. Now GPS positions will be accurately plotted on the map.

Scanning Maps for use within iPLOTTER

===================================

 

You can scan in any map in any resolution for use with iPLOTTER, so long as you can identify two points in terms of latitude/longitude for calibration, and that the lines of latitude/longitude are reasonably parallel in the section scanned.

For greatest accuracy, ensure the maps are scanned as straight as possible.

To reduce map distortions it is better to scan several small areas than one big area, iPLOTTER will automatically load the correct map for the craft position. If the craft moves to an area that has not been scanned, a default low-resolution map will be loaded.

Save the bitmaps as .jpg files and reduce the number of colours to 256 to reduce the size of the file.

Using the explore function of 'Microsoft ActiveSync', copy the bitmaps to the folder

where you installed iPLOTTER... usually \Program Files\iplotter\ on the PocketPC

Now you can load and calibrate the maps as described above.

 

For desktop map calibration use our ‘MapCalib’ utility. A help file is supplied with this software.
