Last Map" configuration option set, the Blank Map will be created automatically.

When first created the Blank Map will be calibrated to cover the entire world. When you load data

from file or download data from the GPS the map will automatically rescale itself so the data will fit

completely on the map. When any additional data is added or deleted manually, you can use the

ReScale Blank Map

option on the Map Menu. Other than by using the zoom option there is no way

for the user to set this scale.

By default a 10 degree grid is drawn on the map, different grids can be selected by choosing the

Blank Map Grid

on the Map menu.

Magnetic Variation

The Magnetic Variation is used to calculate Magnetic Headings or Bearings from True Headings or

Bearings and vice versa.

OziExplorer has 3 methods of obtaining the Magnetic Variation.

1. It can be manually entered for each map in the Calibration screen, this is optional.

2. It can be obtained from the GPS when connected and actively doing real time tracking

It can be calculated by OziExplorer for any position on the globe for any given point in time.

Which Magnetic Variation is used

When calculating bearings for "Routes" and "Distance between waypoints (bearings)" the manually

entered Magnetic Variation is used, if this has not been entered the calculated Magnetic Variation is

used.

When displaying a route for navigation but the GPS is not active then the manually entered Magnetic

Variation is used, if this has not been entered the calculated Magnetic Variation is used.

When displaying a route for navigation and the GPS is active and is transmitting the Magnetic

Variation or Magnetic Course then this reading is used, if the reading is not available then the

manually entered Magnetic Variation is used, if this has not been entered the calculated Magnetic

Variation is used.

Seamless Maps (Experimental)

This method of displaying many maps at the same time is experimental and does have some

limitations which are explained below.

Overview

A seamless map can be thought of as a container which can have many OziExplorer maps

loaded into it. For Example : load a seamless map (.map) file and all the maps contained in the

map file will be loaded.

You can have many seamless maps with each one having many loaded maps.

To setup your seamless map

As you would normally load a map in OziExplorer, load the

map file "Seamless.map" and use the Seamless Map Control to add your maps. The options on

the "Options Menu" allow you to create additional seamless map files.
