Imagenum File (IMAGENUM.txt)
This file keeps track of the numbering of the images in the IMG and Pix4D log files. To restart the
numbering at 1, simply delete the IMAGENUM file from the GeoSnap microSD card.
SYNCHRONIZING IMAGE NAMES
The GeoSnap does not get the actual image names from the camera but uses a sequential
numbering scheme in the specified image name format. Because of this, it is important that the
camera and the GeoSnap be set up so that they both start image numbering at 1 and remain
synchronized through use.
It is recommended to set the camera’s file numbering setting to Reset (for more information on
this, see the Camera Settings section of this manual). Then, before you start a new mission, clear
all images off the camera’s SD card and delete the IMAGENUM.txt file off the GeoSnap card. This
will reset both systems to start image numbering at 1.
CONFIGURING FOR MAPPING FLIGHTS
For mapping missions, we recommend setting up the GeoSnap to trigger the camera using the
distance interval option. The appropriate distance interval can be obtained from your flight
planning software, or from Field of View’s flight planning calculator, available at
fieldofviewllc.com/downloads. To configure the GeoSnap for distance interval triggering:
1. Insert the GeoSnap microSD card into a computer
2. Open the CONFIG.txt file using a text editor (e.g. Notepad)
3. Edit the following CONFIG file options to the specified settings, then save and replace
microSD card in the GeoSnap
@2: File_name = camera dependent (select the correct option for your camera)
@3: Trigger mode = 2
@5: Trigger_dist_m = your desired trigger distance interval in meters
@20: Antenna_offset_m = installation dependent (see the Configuration File
section of this manual for more information on how to properly use this option)
POWERING ON THE GEOSNAP
To power on the GeoSnap, simply plug in the provided USB power cable, or the power pigtail
cable connected to an appropriate power source (see the Specifications section of this manual
for power specifications). Before powering down the system, press and hold the onboard button
for approximately 3 seconds until all LED shine solid. This ends logging, making it safe to remove
power from the system.
Dynamic Motion
The VN-200 requires dynamic motion to reach full heading accuracy. Because of this, if you are
using the GeoSnap Pro on a multirotor, we highly recommend performing a few S-turns in
manual flight mode at the start of the flight before sending it on its autonomous mission.
