This is the manual for the latest version of BackCountry Navigator. This manual is text only, and explains the screens and menus of the BackCountry Navigator software.
If there is a map file loaded, the map page shows the map image data along with points of interest. The items that are shown are controlled by the View Menu.
Moving the map allows you to pan to different parts of it. To pan, drag the image with the stylus. After you lift the stylus, the map will redraw in the new position.
To zoom in on the map, press the down arrow key or View-> Zoom -> In. To zoom out, press the up arrow key or View -> Zoom -> Out. Using View -> Zoom -> Zoom to Default will attempt to find a default center and scale of the map currently loaded. Set Default will set this default. The Zoom Control at the top of the map allows you to quickly jump to a particular scale. It also marks the approximate size of a small line on the screen to give you an idea of the scale.
To mark a point on the map, tap the screen (press and release). Small red crosshairs will mark the last point tapped. The Select Menu will then have an option to view a point of interest or create a new one. On the Select Menu, you can also choose to mark lines or rectangles by tapping the screen multiple times.
When a GPS has a fix on your current location, the GPS pointer will appear on the map. The center of the circle is the current location, while the arrow within the circle indicates the direction of travel. A line will draw from the GPS Pointer to a Goto Waypoint if one is active.
The bottom portion of the map screen contains a panel with brief information about navigation. It contains the following information from left to right:
The List Page is for organization and lookup of points of interest. Use the menu item Action->List to choose a set of points. The points will display in a grid, for which you can resize the columns. You can choose the following lists:
You can use the Clear button to clear the list. The grid view of the list allows you to resize columns if needed. You may also scroll through the list, and select an item by highlighting a row. Once a row has been selected, you can choose a button for the following actions:
When using a GPS, this page will track your position and movement, and when activated, your progress toward a Goto waypoint.
The left half of the screen shows your speed and direction of travel. Note that this is only valid when moving fast enough for the GPS to measure. You must use a compass to find directions when standing still.
The altitude, longitude, and latitude are also displayed when returned by the GPS.
The top of the compass indicates direction of travel This indicates a moving direction that the GPS can detect and does not reflect the direction in which the mobile device is pointed. If a waypoint is active, an arrow points in its direction. This aids navigation by indicating if you need to steer right or left to reach the waypoint.
The right side indicates distance and direction to a Goto waypoint, when active. A waypoint is activated by the Goto option on the Select Menu, or the Goto button on the List page.
The GPS Page lets you connect to a GPS device, and monitor its communication with satellites.
Satellite view
After communication is established, the satellites are shown in a diagram. Colors indicate the relative clarity of communication.
GPS Time
The time as returned by the GPS satellites.
ER (Position Error)
An estimate of the accuracy of the current position, Horizontal followed by Vertical. Vertical error is usually more than horizontal. This indicates a bound of how far the GPS position might be off.
Detect
The detect button will switch to Automatic mode and begin to detect a GPS Device by checking the serial ports to see if an NMEA Gps deivce responds. If successful, a detected GPS will show up in the drop down box.
Connect/Disconnect
The Connect button will connect you to the GPS and begin the process of getting a fix on your position. If a detection is still in progress, this will interrupt the detection process and connect to whatever device has been detected. If a port and baud rate have been chosen manually, it will connect to the port and baud rate specified.
This button will become a Disconnect button after connecting.
< Button
The angle bracket button will switch between manual and automatic mode. In manual mode, the Port and Baudrate selection boxes appear. In automatic mode, a single drop down box appears. This is filled with the names of devices found when you use the detection button.
Allows you to choose the datafile that is currently loaded, and load data from other files or the internet.
A map datafile contains image data and points of interest for a specific location of your choice. Files will generally have the extension .db3. You can browse to a file on your device by pushing the Open button or choose a name for a new one by pushing the New button.
You must have an open data file in order to perform many of the operations needed. Some of the buttons below will be grayed until you have chosen a filename.
Topographic maps and aerial photography can be loaded from Terraserver. Clicking the button will bring up a dialog that allows you to choose center point and region size. The center point will default to the current center of the map screen. You must be connected to the internet in order to download this data.
This will download points of interest from USGS geographic features database.You must be connected to the internet in order to download this data.
This button brings up the Placefinder dialog, to search for a particular place by name and state. Successfull completion of this dialog will add the chosen place to the current map database. This is often a starting point for choosing a region to download.
This will download places for the region currently covered by the map screen. It may take a few minutes.
You can import waypoints from a file in GPX (GPS Exchange) format. This is the format that can be downloaded by geocaching.com members. Waypoint data in GPX format can also be produced by several desktop software programs, and is available at several places on the internet. Some will contain tracks as well as waypoints.
You can also import waypoints in LOC format. This will the waypoint name and coordinates only and will not have the long description.
The File Open Dialog will appear, allowing you to choose a file on your Pocket PC to import. To explore the Pocket PC and drag files from the desktop, choose the Explore button on ActiveSync.
The Export button allows you to export the data in you file as GPX (GPS Exchange Format). All waypoints and tracks from the currently loaded file are exported.
The View Menu allows to you to enable various types of data to be displayed on the map.
This menu controls type of selection and allows you to operate on a location that has been chosen on the map.
This dialog allows you to download map data from TerraServer web service. You will specify a center point and dimensions of a rectangular region. The Center Point is initially set to the center of the map screen.
Center Lat: Latitude of center point.
Center Lon: Longitude of center point.
PlaceFinder: This button will take you to the Placefinder to find latitude and longitude by findng a place name. Upon returning, the longitude and latitude of the place you find will be filled in on this dialog.
