If user and file serial numbers match, the KML software will begin processing the GPS
data. Be patient, this may take a few minutes based on file size and computer speed.
WHAT IS THE “.ACK “ FILE AND WHAT IS ITS PURPOSE.
After GPS data is processed, a new encrypted file is generated. This is the “ACK” file.
This file will be saved to the same location as the original GPS file. For example, if the
user GPS data is stored in “C:\USERS\GPS” then the ACK file will be generated there as
well.
When the KML 5000 is writing data to a media card it will check for the existence of an
ACK file. The ACK file contains the most recent dates and times collected by the KML
5000.
If a valid ACK file exists on the media card the KML 5000 will only write data that is
more recent than what data is contained in the existing ACK file.
NOTE:
If a valid ACK file is not found on the media card, all GPS data will be written to the media card.
WORKING WITH GPS DATA
Now that you have imported the user GPS data lets figure out what it means.
After the ACK file is written the KML software will select the most recent date for which
there is data for the selected user and plot that data to the screen. It is possible to display
more than one user and or date at a
time, however in the case of a single user the GPS
data is color coded for speed indication. If more than one user is displayed GPS data is
color coded by user only.
To display more than one user or date click on the USER or DATE drop down menus and
using the control (Ctrl) or shift (Shift) keys with the left mouse button to select a range of
users or dates. Keep in mind when working with multiple users or dates, it may take some
time for your system to display the data.
You may also move or delete line segments with the mouse to see the layered data. This
affects only the display and not the actual GPS data.
