Images may have associated geographical data, either recorded when the image was captured or set later (e.g., using the PanGazer Image Geography dialog).

In particular, if an image being viewed has latitude and longitude information (is ‘geotagged’) then you can display its location on a map by clicking on one of the options in the Image menu:

• Show location on satellite map – this opens Google Maps centred at the image location, showing the Satellite view with a location marker pinpointing where the camera was when the image was captured.  (This option is also available from the right-click pop-up menu.)

• Show location on regular map – this similarly opens Google Maps, but shows the regular Map layer; this is less useful but is often faster.

• Show location using GPX (map) viewer – if an application is installed which is associated with the .gpx file extension (used for Global Positions eXchange format files) then PanGazer writes a temporary file including the location as a Waypoint with the name of the Image and then opens it with the default application for GPX files.  Applications which can be associated with GPX files include MapGazer » and MemoryMap.

• Show location using KML (earth) viewer – if an application (such as Google Earth) is installed which is associated with the .kml file extension (used for Keyhole Markup Language files) then PanGazer writes a temporary file including the location as a Placemark with the name of the Image and then opens it with the default application for KML files.

Further, if North is set for the image (see Setting North) then if you right click on a point on the image you can then select on the pop-up menu:

• Show direction using GPX (map) viewer

• Show direction using KML (earth) viewer

These will show the location (as described above) and also draw a line in the viewer that extends from the image location for 5 kilometres in the direction of the point that was clicked – this can be help identifying features in the view.  The line includes ‘ticks’ (cross marks) each kilometre.

Note that if the line appears to ‘miss’ the feature clicked, the North setting for the image needs adjusting (see Setting North). Also, in extreme terrain, the view of the line might not include the location ‘pin’ – in this case just adjust the viewpoint.

 
The files created for the last four options (show using a GPX or KML viewer) are transient and will be deleted when PanGazer is closed. If you want to save a permanent GPX or KML file, click the Image menu option:

• Save location as ... – this opens a save dialog starting at the image source directory or at the directory where you last saved a GPX or KML file.  You can save the location as either a .gpx or a .kml file. The save dialog is initialised with a suggested file name constructed from the name of the Image and with the same extension that you last used to save a location (the first time you save a location the suggested extension depends on the viewers available).

  You do not need to have a GPX or KML viewer in order to save a GPX or KML file (for example, you can save a GPX file then use a web application to view it).  However, if an appropriate application is installed then PanGazer will automatically use it to open the saved file.

Note: For showing the location with Google Maps or Google Earth an internet connection is required.  Other viewers may or may not require an internet connection; for example, MapGazer » is designed to be able to work offline.
