CONFIGURATION FILE SNAPSHOT
The yyyy-mm-dd_hhmmss_config_snapshot.html file is an HTML file that contains the parameters used for the
session. While the original CONFIG file is in the root directory and is used to change GeoSnap settings, the CONFIG
file snapshot cannot be changed and is found in every session folder that gets generated. Note that an internet
connection is not required to view the CONFIG file snapshot.
GEOTAGS TOOL
The Geotags Tool is a simple application that gets written to every session folder. It has three main functions:
1.
It creates a Pix4D and Agisoft compatible
“geotags file”
using the position data from the events file and
the image name/numbering scheme you specify.
2.
It creates a KML file that allows you to quickly see your geotags in 3D using Google Earth.
3.
It can embed geotags and their accuracy estimates into the metadata (Exif and XMP) of your images.
The following are two different step-by-step guides on how to use the Geotags Tool. The first focuses on how to
create the geotags file and KML file only, while the second focuses on how to also embed coordinates into the
metadata of your images. A video of the process can also be found at
