NAME
viking - program to manage GPS data
SYNOPSIS
viking [-d | --debug] [-V | --verbose] [file...]
viking [-h | --help]
viking [-v | --version]
DESCRIPTION
Viking is a free/open source program to manage GPS data. You can import and plot tracks and waypoints, show OpenStreetMap (OSM) maps and/or
Terraserver maps under it, add coordinate lines, make new tracks and waypoints, hide different things, etc. It is written in C with the
GTK+ 2 toolkit, available for Linux, other POSIX operating systems, and Windows, and is licensed under the GNU GPL.

-v, --version

EXTENDING VIKING
Currently, viking has some extention points based on configuration files. The file format is heavily inspired by the GtkBuilder file
format: you specify the class of the GObject to build and set its properties. Technically, it is a XML file containing a "objects" root
element. Inside this element, you set a collection of "object".
Here is an example:
<objects>
<object class="ClassName">
<property name="property_name1">Property value</property>
<property name="property_name2">Property value</property>
</object>
...
<objects>
You can find more examples in the documentation part of the distribution.
Map Source. It is possible to add new map's sources. The file is ~/.viking/maps.xml. An example of the file in the distribution
doc/examples/maps.xml. The VikSlippyMapSource allows to declare any map's source working like OpenStreetMap. It supports the following
properties:
id
this is an integer and should be unique as it used to identify the map source
label
the text displayed in the map's source selection dialog
hostname
the server's hostname (eg. "tile.openstreetmap.org")
url
the parametrized address of the tile, in the spirit of C printf format, with 3 "%d" fields for X, Y and Z (zoom level) (eg.
"/%d/%d/%d.png")
The VikTmsMapSource allows to declare any TMS service. It supports the following properties:
id
this is an integer and should be unique as it used to identify the map source
label
the text displayed in the map's source selection dialog
hostname
the server's hostname (eg. "tile.openstreetmap.org")
url
the parametrized address of the tile, in the spirit of C printf format, with 3 "%d" fields for X, Y and Z (zoom level) (eg.
"/%d/%d/%d.png")
The VikWmscMapSource allows to declare any WMS or WMS-C service. It supports the following properties:
id
this is an integer and should be unique as it used to identify the map source
label
the text displayed in the map's source selection dialog
hostname
the server's hostname (eg. "tile.openstreetmap.org")
url
the parametrized address of the tile, in the spirit of C printf format, with 4 "%s" fields for bounding box coordinates (eg.
"/coord=%s,%s,%s,%s")
Go-to search engines. It is possible to add new new search engines for the "Go-To" feature. The file is ~/.viking/goto_tools.xml. An
example of the file in the distribution doc/examples/goto_tools.xml. Currently, there is a single object class available: VikGotoXmlTool.
Such feature allows to declare any search engine using a XML format as result. The related properties are:
label
the text displayed in the Go-To dialog
url-format
the parametrized address of the query, in the spirit of C printf format, with a single "%s" field (replaced by the query string)
lat-path
XML path of the latitude (eg. /root/parent/elem)
lat-attr (optional)
name of the attribute (of previous element) containing the latitude
lon-path
XML path of the longitude (eg. /root/parent/elem)
lon-attr (optional)
name of the attribute (of previous element) containing the longiude
As a facility (or readability) it is possible to set both path and attribute name in a single property, like an XPath expression. To do so,
simply set both info in lat-path (or lon-path) in the following format: /root/parent/elem@attribute.
External tools. It is possible to add new external tools. The file is ~/.viking/external_tools.xml. An example of the file in the
distribution doc/examples/external_tools.xml. Currently, there is a single object class available: VikWebtoolCenter. Such feature allows
to declare any Webtool using a logic based on center coordinates and zoom level value. The related properties are:
id
this is an integer and should be unique as it used to identify the tool
label
the text displayed in the menu entry
url
the parametrized address of the tile, in the spirit of C printf format, with 3 "%d" fields for X, Y and Z (zoom level) (eg.
"http://hostname/%d/%d/%d.png")
