+ Site Map
+
+ When the rocket gets a GPS fix, the Site Map tab will map
+ the rocket's position to make it easier for you to locate the
+ rocket, both while it is in the air, and when it has landed. The
+ rocket's state is indicated by colour: white for pad, red for
+ boost, pink for fast, yellow for coast, light blue for drogue,
+ dark blue for main, and black for landed.
+
+
+ The map's scale is approximately 3m (10ft) per pixel. The map
+ can be dragged using the left mouse button. The map will attempt
+ to keep the rocket roughly centred while data is being received.
+
+
+ Images are fetched automatically via the Google Maps Static API,
+ and are cached for reuse. If map images cannot be downloaded,
+ the rocket's path will be traced on a dark grey background
+ instead.

Graph Data
- This section should be written by AJ.
+ Select this button and you are prompted to select a flight
+ record file, either a .telem file recording telemetry data or a
+ .eeprom file containing flight data saved from the TeleMetrum
+ flash memory.
+
+
+ Once a flight record is selected, the acceleration (blue),
+ velocity (green) and altitude (red) of the flight are plotted and
+ displayed, measured in metric units.
+
+
+ The graph can be zoomed into a particular area by clicking and
+ dragging down and to the right. Once zoomed, the graph can be
+ reset by clicking and dragging up and to the left. Holding down
+ control and clicking and dragging allows the graph to be panned.
+ The right mouse button causes a popup menu to be displayed, giving
+ you the option save or print the plot.
+
+
+ Note that telemetry files will generally produce poor graphs
+ due to the lower sampling rate and missed telemetry packets,
+ and will also often have significant amounts of data received
+ while the rocket was waiting on the pad. Use saved flight data
+ for graphing where possible.
