Image Log File (001-IMG.TXT)
The IMG log file is a log of the image name and position of
the camera at the moment of image capture.
Pix4D Image Log file (001-P4D.TXT)
The P4D log file is a Pix4D compatible log of the image name
and position of the camera at the moment of image capture.
Flight Log File (001-FLT.TXT)
The FLT log file is a 25Hz log of the position of the camera
throughout the flight.
IMAGENUM.TXT
This file keeps track of the numbering of the images in the
IMG log file. To restart numbering at one, simply delete this
file from the GeoSnap microSD card.
GeoSnap File Descriptions
The GeoSnap does not get the actual image names from the
camera but just logs the correct image name format with a
sequential numbering scheme. Because of this, it is
important that the camera and the GeoSnap be set up so
that they both start numbering the images at 1 and remain
synchronized through use.
It is recommended to set the camera’s file numbering
setting to Reset. Then, before you start a new mission, clear
all images off of the camera’s SD card and delete the
IMAGENUM.TXT file off of the GeoSnap card. This will reset
both systems to start image numbering at 1.
Image Name Synchronization
To improve your GPS accuracy, place a
10cm round or square ground plane
under the GPS antenna. This could be
as simple as placing some aluminum
tape (that you can buy from a
hardware store) around a 10cm piece
of wood or cardboard, sticking the
antenna to the center of the plate,
and attaching that whole assembly to
the top of your aircraft.
