4.1.2. Camera Setup

All digital cameras write timestamps to the images they take. Most cameras however do

not store the time zone they are conﬁgured for. HoudahGeo uses timestamps to match

images to GPS track logs. It needs to know how to interpret the timestamps embedded

in the images.

Camera clock setup thus is the single most important information you need to provide to

HoudahGeo. Automatic geocoding is only possible when this information is accurate.

To set up the camera clock, you may choose from three options.

Time Zone

Camera time zone: the time zone the camera was conﬁgured to at the time the photos

were taken. Typically this is your home time zone or the time zone you have travelled to.

There are three time zone lists to choose from: named time zones, GMT offsets and

time zone abbreviations.

Clock error: the number of seconds your camera's clock was fast at the time the photos

were taken. If you have accurately set the time on your camera, this value should be 0.

Current camera time: enter the time time as currently displayed on your camera. This

assumes that the camera clock has not been reset since the photos to be geocoded

have been taken.
