Operation steps
Power up the feller buncher
Because MobileMap Harvest is connected to a USB port in the feller buncher, and because there is no on/off switch on that port or the MobileMap Harvest unit, it will power up when the machine powers up.
You should see a small flickering yellow light and a small flashing blue light. These may be difficult to see in the lighting of the cab, but are good indicators that the harvest unit is powered up and ready to be connected to MobileMap
Power up the Android device running MobileMap
Verify that GPS is connected and that location information is available
Coordinates should display in the upper left corner of the screen
A blue dot should show your location on the map
Using the autopan button will center the map at your current location
Verify that the situation awareness panel is displayed in the lower right corner of the map. It should display
Bearing
Speed
Connect MobileMap to MobileMap Harvest Module
Tap the gray Bluetooth icon on the Situation Awareness Panel to initiate connection
Icon will flash blue (similar to flashing blue light in MobileMap Harvest Module) to indicate that it is searching for the MobileMap Harvest Module
If the icon does not flash blue when tapped, this likely means that Bluetooth is not enabled on the tablet. Enable Bluetooth on the Android MobileMap tablet by going into the device settings (see details in MobileMap Configuration above)
When the connection is made, the icon will change to solid blue and the MobileMap Harvest Module will beep once (ascending single beep) to indicate a successful connection
At this point the MobileMap and the MobileMap Harvest Module are ready to collect data
To disconnect MobileMap from the MobileMap Harvest Module, tap the Bluetooth icon
It will turn gray to indicate that it is no longer connected to the MobileMap Harvest Module
The MobileMap Harvest Module will beep twice (descending double beep) to indicate that the connection was lost, and the blue light will resume flashing to indicate it is broadcasting its availability for a new connection.
If MobileMap is properly closed (e.g., Actions > Close MobileMap) and restarted, or if the the tablet is restarted, it should properly disconnect from the MobileMap Harvest Module. When MobileMap restarts, the Harvest Module should be ready to reconnect and resume data collection.
If MobileMap is force-closed without restarting the tablet (e.g., app is first backgrounded then swiped closed from the recent apps list) the Harvest Module may maintain the connection to the tablet, but MobileMap will not have access to that connection when it is restarted. If this occurs, the blue LED light in the Harvest Module will display solid blue (rather than blinking blue). When the LED light is solid blue, it cannot make a new connection. If this occurs, restart the module by unplugging and re-plugging the USB connection to the Harvest Module. Then proceed with the bluetooth connection from MobileMap as normal.
If MobileMap is backgrounded temporarily (e.g., start button pressed, then other app like email is opened) and then MobileMap opened by selecting from the recent apps list, it should maintain the connection to the Harvest Module in the background and maintain the ability to record tree harvest data.
...
The Harvest Module will automatically detect each tree harvest event by sensing the current on the circuit coming from the accumulator arm trigger button.
That signal will then be sent via Bluetooth (BLE) to MobileMap.
MobileMap will receive that event, then send a return signal to the MobileMap Harvest unit to inform it that the signal was received and it should prepare for the next harvest event
MobileMap then processes the harvest even in order to store the tree harvest information
The GPS-derived location is used to establish the coordinates of the GPS antenna
If no GPS location is obtained, MobileMap will display the following message
The last available bearing information (recorded the last time that the GPS speed was above the “Harvest Minimum Speed for Bearing” setting) is retrieved from storage. Note that if the vehicle has stopped moving and a stored bearing is being used, this will be indicated in the Situation Awareness Panel via the suffix “(old)” by the bearing value.
The “Harvest GPS Offset” is retrieved from settings
The location, bearing and offset are used to calculate the location of the harvest tree by projecting the coordinates into Albers Equal Area Conic projection then applying basic trigonometry to calculate the x and y offsets and finally the harvest tree location
The harvest tree location is used to create a tree point feature and save it
MobileMap will issue an audible beep to let the operator know that the data was captured
There are no actions that an operator needs to take in order to record tree harvest events or locations.
To pause data collection (e.g., to test the accumulator arm button without recording a tree harvest event) tap the pause button. The pause button will change from gray to yellow to indicate that MobileMap Harvest collection is paused
To resume data collection after pausing, tap the gray play arrow (between Bluetooth icon and pause icon). The play button will turn from gray to green to indicate that MobileMap Harvest collection is enabled.
To undo the last collected tree (e.g., when MobileMap testing data collection, or if MobileMap recorded 2 trees when only one was harvested) tap the undo button.
