2 Reviewing: O-2205 View & Sort Photos on a Computer l Use an photo browser or a photo processing program to sort and delete unwanted photos l For a general purpose photo browser, we recommend View. NX 2 (alternate: Irfan. View) – – l To modify a photo, in most cases we recommend Nikon View. NX 2 (alternate: Picasa) – – – l Free application, see irfanview. com (PC Only) Used for quick image viewing, key EXIF metadata viewing 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 View. NX 2 (alternate: Phyllis) (see next module) – Adds labels with geo-tag and photo description details

3 Reviewing: O-2205 EXIF Metadata l 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: l – 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 l This is referred to as geotagging or geolocation

4 Reviewing: O-2205 Viewing EXIF Metadata l On the D 7100/D 90/D 200, you can view some of your photo’s EXIF data – l 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. View. NX 2, etc. ) In Windows, you simply right-click on the photo and select “Properties” and then select the ‘Details’ tab.

6 Reviewing: O-2205 Post Flight Geotagging Photos l Manual method: – – l Use View. NX 2, 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 View. NX 2 to synchronize track to photos via GPS / Camera time stamp. l – Accurate clock synchronization preferred Location automatically entered in EXIF data.

8 Reviewing: O-2205 View. NX 2 – Manual Geotagging l l l 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: N 34 56. 7 W 112 33. 3 Move crosshairs to desired location & left click – l No LL readout of crosshair location for first time location entry, move pin slightly to get LL readout Confirm location update

9 View. NX 2 – Auto Geotagging l l l Select photo or group of photos to geotag Select Log Matching Click Add to select desired nmea log file Click Save and photo(s) will be updated with location Click icon to view track Reviewing: O-2205

13 Reviewing: O-2205 Picasa Geotagging – Quick Method (Internet Connection Preferred for Map) l l 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 – – l LL Format: N 34 56. 7 W 112 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)

14 Reviewing: O-2205 Picasa Geotagging – GE Method (Internet Connection Required) l l Works in conjunction with Google Earth app (must be installed) Select the photo (or group of photos), select the ‘Tools’ drop-down – l Google Earth will open & after a short delay, crosshairs will be displayed on GE. – l l l Select “Geotag” then “Geotag using Google Earth”. 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)

15 Reviewing: O-2205 Flight Data Logging l l l http: //www 8. garmin. com/support/download_details. jsp? id=5059 With a SD Card plugged in the top slot of the MFD, the G 1000 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 2 GB. Don’t not use high speed data cards (e. g. SDHC, etc) Garmin Software Tool Goggle Earth View 4. 5 MB. csv file size for 3 op hours

17 Reviewing: O-2205 Nikon Geotagging l 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 l Repeatedly check GPS status during photo runs D 90/D 7100 D 200
