Images may have associated geographical data, either recorded when
the image was captured or set later (e.g., using the PanGazer Image geography dialog box).
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 popup menu.)
- Show location on regular map – this similarly opens Google
Maps, but shows the regular Map layer; this is less useful but is
often much 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
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 (usually Google Earth).
The files used for the last two options 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
For showing the location with Google Maps or Google Earth an internet
connection is required. Other viewers may or may not require an
interconnect connection – for example, MapGazer is designed to be
able to work offline.
