<p><a name="What is a Map"><font COLOR="#0000ff"><big><b>What is a Map</b></big></font></a></p>
<p>A map in OziExplorer is an image of a map which has been calibrated (georeferenced) so
OziExplorer can use any pixel position on the map to determine the true geographic
position. </p>
<p>When you calibrate a map in <font color="#FF0000"><b>PC</b></font> OziExplorer <strong>a map file with a .map extension</strong>
is created which contains the calibration information and a link to the image of the map
you are using.</p>
<p>A <strong>Map</strong> file therefore contains at least this information
<ul>
<li>A link to the image of the map</li>
<li>The datum of the map</li>
<li>The map projection used for the map</li>
<li>The calibration (georeferencing) information for the map </li>
</ul>
<p>Map Calibration and the creation of the .map file must be done in
<font color="#FF0000"><b>PC</b></font> OziExplorer and then copied to the
device.</p>
<p>When you want to use a Map in OziExplorerCE you must open a Map file which has a <strong>.map</strong>
extension (example name : World.map). </p>
<p>OziExplorerCE then reads from the Map file
<ul>
<li>The name of the <strong>map image file</strong> from the <strong>.map</strong> file and
opens the image. </li>
<li>The map datum and map projection are read.</li>
<li>The calibration information from the <strong>.map</strong> file and calculates the
factors necessary to convert the map image pixel coordinates to geographic coordinates.</li>
</ul>
<p>A map consists of 2 files
<ol>
<li>The .map file which contains the information detailed above</li>
<li>The image file (.ozf2) which is the image of the map</li>
</ol>
<p>Before map images can be used in OziExplorerCE they must be converted to the ozf2 format using the img2ozf.exe program. This program is available from the web site
www.oziexplorer.com</p>
<hr color="#000080">
<p><a name="Opening"><b>Opening a Map</b></a></p>
<p>Use the Open Map File option on the File menu or the button on the Toolbar.</p>
<p>Maps (the .map file) must be created in the full OziExplorer on a PC and then copied to
the CE device, OziExplorerCE does not have the capability to create maps.</p>
<p>Select a map to load from the list in the Open Map File dialog. (You can navigate
through the folders on your system to find a map path.) </p>
<hr color="#000080">
<p><a name="How a Map Image is Searched For"><strong>How a Map Image is Searched For</strong></a></p>
<p>OziExplorerCE searches for map images in this order.</p>
<p>The map image name is read from the .map file and the path and file extension removed.</p>
<p>The .ozf2 extension is added to the file name.
<ul>
<li>The <strong>Image File Path 1</strong> is searched for the name.</li>
<li>If not found <strong>Image File path 2</strong> is searched.</li>
</ul>
<p>If not found
<ul>
<li>The <strong>path where the .map file was loaded from</strong> is searched.</li>
</ul>
<p>If not found then the name of the <strong>map file name</strong> is used for the image
name and the above process repeated.</p>
<p>If all this searching fails the message "<b>I</b><strong>mage File not Found</strong>"
will be displayed.</p>
<hr color="#000080">
<p><b><a name="Index Files">Index Files for Faster Map Searching</a></b></p>
<p>For faster map searching, the map files are indexed and the indexes are
stored in the "System Files" folder attached to the main "OziExplorer" folder. </p>
<p>These index files are created the first time a map search is initiated. The
time it takes to create the indexes for the first time will vary depending on
the number of map files in each of the active Map File Paths (see Configuration
/ Map & Data Files).</p>
<p>The indexes are used to find maps when - </p>
<ul>
<li>looking for a map during moving map operation if the "More Detailed Map"
option is turned on</li>
<li>using the Map Menu or Screen Control options
<ul>
<li>Find Maps at Cursor</li>
<li>More Detailed Map</li>
<li>Less Detailed Map</li>
</ul>
</li>
</ul>
<hr color="#000080">
<p><b><a name="Scrolling">Scrolling</a> the map</b> - There are 3 ways to scroll the map.
<ol>
<li>Tapping the screen with the finger or stylus moves the point you tap to the center of
the screen. Tapping near the edge of the screen scrolls quicker than tapping near the
center. </li>
<li>Moving the stylus across the map will drag the map. If "Drag Object" is
selected, do not press on an object at the start of the drag motion or the
object will be moved. </li>
<li>Using the arrow or cursor keys if available. </li>
</ol>
<p><strong><font color="#0000FF">You cannot scroll while -</font></strong>
<ul>
<li><strong><font color="#0000FF">in moving map (real time tracking) mode </font></strong></li>
<li><strong><font color="#0000FF">or when the screen control is activated.</font></strong></li>
</ul>
<hr color="#000080">
<p><b><a name="Map Objects">Map Objects</a>, Popup Information and Menu</b></p>
<p><b>Popup Information - </b>Press and hold the stylus on the map or any map
object (waypoint, route waypoint or active track
point) until a red circle appears (approximately 0.5 seconds), release the stylus to show a
window with information about the map or map object. (The circle color may
change depending on the underlying map color.)</p>
<p>The window will display for 10 seconds, to hide it immediately tap the stylus on the
window.</p>
<p><b>Popup Menu - </b>Press and hold the stylus on the map or any map object (waypoint, route waypoint or active track
point) for at least 1 second to show a popup menu with several menu options. The
map popup menu has zoom selections, Full Map or 100% Zoom. Map Object popup
menus are different for each object type.</p>
