View & Sort Photos on a Computer Use an photo browser or a photo processing program to sort and

delete unwanted photos

For a general purpose photo browser, we recommend ViewNX2 (alternate: IrfanView)

– Free application, see irfanview.com (PC Only)– Used for quick image viewing, key EXIF metadata viewing

To modify a photo, in most cases we recommend Nikon ViewNX2 (alternate: Picasa)

– Free applications, see picasa.google.com (PC or Mac)– Change EXIF data & add location coordinates– Photo resizing, cropping, etc. (covered in next module)

To label a photo, we recommend ViewNX2 (alternate: Phyllis) (see next module)

– Adds labels with geo-tag and photo description details

EXIF Metadata Exchangeable Image File Format

– A standard that specifies the formats for images, sound, and ancillary metadata tags used by digital cameras

– The EXIF metadata information is part of the image file and is readable and changeable by computer apps

– Data parameters include: Camera specs & time stamp, image data,

latitude/longitude data, etc.

– Lat/lon location data is saved in the EXIF metadata if available to the camera when the photo was captured

This is referred to as geotagging or geolocation

Viewing EXIF Metadata

On the D7100/D90/D200, you can view some of your photo’s EXIF data – While the photo is displayed on the LED screen, you press the

multi selector down to scroll through the photo’s EXIF data.

Post sortie viewing EXIF data:– Most photo viewing applications allow you to view EXIF data

(e.g. ViewNX2, etc.)– In Windows, you simply right-click on the photo and select

“Properties” and then select the ‘Details’ tab.

Post Flight Geotagging Photos Manual method:

– Use ViewNX2, etc. to open selected photo, locate lat/lon on a map then transfer/type in location to the photo

– Using “satellite” background map is useful to determine picture direction

Automated method:– Capture GPS track during the flight & import

the GPX track file– Use ViewNX2 to synchronize track to photos

via GPS / Camera time stamp. Accurate clock synchronization preferred

– Location automatically entered in EXIF data.

ViewNX2 – Manual Geotagging Select Add/Edit location icon Slew map to desired area or search for a

place– Also can enter known place or lat/lon

coordinates to position map (i.e. roughly center of map)

– LL Format: N34 56.7 W112 33.3

Move crosshairs to desired location & left click

– No LL readout of crosshair location for first time location entry, move pin slightly to get LL readout

Confirm location update

Picasa Geotagging – Quick Method(Internet Connection Preferred for Map)

Use Picasa & internal Google map engine

Select the photo (or group of photos), select red place mark button

Map will appear & slew to geotag info if available, can reposition manually

Also can enter known place or lat/lon coordinates to position map

– LL Format: N34 56.7 W112 33.3– If no internet, map will still slew to

lat/lon coordinates (w/no map picture) Place green marker at desired

location and select OK to encode photo (no undo)

Picasa Geotagging – GE Method(Internet Connection Required)

Works in conjunction with Google Earth app (must be installed)

Select the photo (or group of photos), select the ‘Tools’ drop-down

– Select “Geotag” then “Geotag using Google Earth”.

Google Earth will open & after a short delay, crosshairs will be displayed on GE.

– Note all photos in Picasa catalog may be overlaid on GE, can get busy

Move map to align crosshairs with target location

Advantage of GE: also can rotate map to determine picture direction

Then select Geotag & Done to encode photo (no undo)

Flight Data Logging With a SD Card plugged in the top slot of the MFD, the G1000 will

continuously records numerous flight parameters every second This allows you to remove the SD card and play back the flight on

Google Earth using a Garmin supplied software tool Notes:

– SD card should only be inserted or removed with the MFD power OFF! Otherwise there is a high risk of scrambling all the data on the SD card.

– The system works best with standard low speed SD cards up to 2GB. Don’t not use high speed data cards (e.g. SDHC, etc)

4.5 MB .csv file size for 3 op hours

Nikon Geotagging

Geotagging photos depend upon a good connection between the camera and the GPS, and reliable GPS data depends upon the unit being locked on to a sufficient number of satellites

Repeatedly check GPS status during photo runs
