Here all GPX files are loaded into a new Viking project in one window.

Each Viking project file is opened in a new window.

The GPX files are loaded into the Viking project in one window.

The GPX files are loaded into a new Viking project in a one window and the Viking project is loaded seperately in a seperate window.

viking --latitude 51.4 --longitude -1.3 --zoom 12 --map 13

viking geo:51.4,-1.3?z=12 --map 13

As a special combination when both -V and -d are both enabled at the same time, Viking will not delete some of the temporary files created during the program run. This is especially useful to monitor results of download requests (which need to be interpreted) if they suddenly start failing, as the file will have often more detailed information about the failure mode.

Multiple headers can be specified by separating each part with an '\n'.

The header allows of substitutions of values of the positional Z, X and Y (in that order) values, as per the url option above. Using multiple and/or different ordered values can be acheived via printf() positional argument specifiers. For example:

DNT: 1\nLine2: %d %d %d\nReordered: %3$d %1$d %2$d

If the tile source is not a PNG file, then this parameter can be used to specify the naming to give consistent extension filenames on disk.

This can also be useful in reading a tileset from other software which may name tiles in an alternative form, e.g. for Mobile Atlas creator it names them .png.tile

This can also be useful for tilesets already on disk as it will avoid attempting to download any tiles.

Thus with this type the hostname and url parameters are not necessary and are ignored.

Use negative numbers to adjust in a westerly direction.

Typical usage would be aligning differing maps, e.g. aerial imagery may be offset from cadastral maps.

Currently this is a single value that applies to all zoom levels.

Use negative numbers to adjust in a southerly direction.

The default is false.

The default is true.

The ETag value is stored in a separate file in the same directory as the tile to enable checking the value across multiple runs of the program.

Note that unlike custom-http-headers for Tile download requests, it does not perform any value substitions in this string.

Use gpsbabel --help on the command line to find out the supported file types and their codes to process them.

Some format codes are handled natively by Viking such as gpx and kml.

A special format code of viking-geojson-osrm is available for handling responses by OSRM[6] route servers.

For instance using Brouter services, the URL uses a pair of values which is longitude and then latitude. Thus setting this value to FALSE ensures the value substitution is performed in the necessary order.

Note that unlike custom-http-headers for Tile download requests, it does not perform any value substitutions in this string.

The order and meaning of these parameters is given by the url_format_code below

B = Bottom of the current view i.e. minimum latitude

L = Left of the current view i.e. minimum longitude

T = Top of the current view i.e. maximum latitude

R = Right of the current view i.e. maximum longitude

A = center lAtitude of the current view

O = center lOngitude of the current view

Z = OSM Zoom value of the current view. See Zoom Levels[7]

P = selected Point's latitude

N = selected poiNt's longitude

S = A user specified input string requested from the user via a dialog box

Thus for the url example above then the format code should be AO

If it is not defined then the returned file is interpreted internally as a GPX file.

Possible values such as 'kml', 'mapsource' etc.. can be used. See GPSBabel File Formats[8] for the full list.

E.g. "-x nuketypes,routes" can be used to filter all routes from the results.

It is the label of the text input box.

(typically /home/username/.viking)

Typically ~/config/viking/

If you've upgraded Viking to v1.9 and want it to use the new location, you will have to manually move the existing directory (when Viking is not running). e.g. in the command line: mv ~/.viking ~/.config/viking

The User Configuration File Location directory can be overridden for the current session by explicitly setting the configuration directory via the --config-dir command line option. See the section called “Details” for more detail.

See CURLOPT_CAINFO[10]

For Windows(TM) systems: curl_ssl_verifypeer=0

See CURLOPT_SSL_VERIFYPEER[11]

Override the default HTTP User-Agent (which is otherwise generated automatically from a combination of Viking's name, the version and curl information) set in all download requests with the value specified.

Also see CURLOPT_USERAGENT[12]

NB The User Agent for individual downloads/requests can be set via the relevant user-agent property when defining use of additional resources.

To enable the export to the little used GPS Mapper format option, set this to true.

To enable the export to the little used GPS Point format option, set this to true.

Set the integer value for the accuracy level request to the GeoClue service. Values to match the GClueAccuracyLevel[13]:

ATM Only attempts to remove a suspicious first point of a GPX track (as opposed to any points within a track).

Over this speed (in metres per second) for the first pair of points - the first point is removed.

Create new TrackWaypoint layers without showing the layer properties dialog first.

0=No markups. 1=Day marked. 2=Day marked and tooltips created. 3=Auto (timed tooltip creation, so if too slow it reverts to 1).

If the following message is shown in the message log:vik_layers_panel_calendar_update: detail level reduced as taking too longthen consider setting this value to 2 - although with the caveat that calendar refreshes may introduce noticable delays.

Particularly if one often views large .vik files, then changing the visibility of items may be considered just part of the viewing process. Thus maybe you don't want to be notified on exit about such things - in this case you can set this value to true.

Allows using an alternative service for acquiring DEM SRTM files. Note that the layout on the server needs to be split into Continent directories.

Set to true to force the use of HTTP Basic Authentication even when OAuth is available

Options are: Pan, Zoom, Ruler or Select

Time to wait between move scroll events before redrawing

Time to wait between zoom scroll events before redrawing

Sensitivity factor for pinch zooming. Best to use keep this value somewhere between 0.5 and 3.0 - a higher value is more sensitive.

If your desktop environment doesn't automatically mount USB storage devices or you wish to also manage it in Viking - then set this to a device's drive label e.g GARMIN or UUID value.

Viking will then put menu entries under Help so you can be manually perform operations as required.

This is provided as a very basic opt in feature, only allowing specification and management of just one device via some additional menu entries. Presently no intention to make this a more fully fledged feature; USB device management is left to other programs.

In metres.

Go Back or Go Forward requests over this range from the last history location will move back to that position. If within this range it will skip over this location and move on to the next saved history location.

If Viking doesn't automatically detect a high resolution display, you can force the setting here - typically by setting this to 2.

In milliseconds

Viking should show a popup with the name of the current track selected. If it is not shown (perhaps you have a slowish machine), try increasing this value.

Or in Windows it uses C:/Progra~1/Rednotebook/rednotebook.exe - This string value must use Unix separators and not have spaces.

Or in Windows use C:/Progra~1/Stellarium/stellarium.exe - This string value must use Unix separators and not have spaces. Needs to be version 0.15.0 or greater (otherwise due to this Bug[17] means this does not actually work).

Or in Windows it uses notepad - This string value must use Unix separators and not have spaces.

A date format description[18] as passed on to strftime(). Note that when displayed in tables sorting by this column simply uses the text value, rather than the underlying date/time value.

UNIX = "/media/user/GARMIN/Garmin/GPX"

WINDOWS = ":/Garmin/GPX"

Older Garmins limits are typically much lower - Etrex 20/30 is 500

You may want to use something like: "/media/user/GARMIN/Garmin/CustomMaps"

Override the base search location for photographs

A matching dated directory corresponding to the track is attempted of the format /geotag_photo_dir/YYYY/MM/DD

By default Viking uses the low level function gtk_show_uri_on_window() function to open URLs, which typically results in opening a new instance of a web browser.

This can be overridden by setting this configuration value to true and setting the environment variable BROWSER to invoke the desired browser, optionally including command line parameters to invoke the desired behaviour; such as "firefox --new-tab".

One could even have a more complicated string to run a specific version with a specific profile, e.g. BROWSER="/home/rob/Downloads/firefox/firefox -P 'Nightly' --new-tab" viking

Note that if you set BROWSER, other programs may also use this value.

This is not applicable on Windows as currently Viking uses the low level function ShellExecute() method to open URLs.

K = Some text to display at the start of the message - Trkpt

A = Altitude of a Trackpoint

S = Speed of a Trackpoint

B = Vertical Speed (Climb)

C = Course of a Trackpoint

L = Location of a Trackpoint

T = Time of a Trackpoint

M = Time diff of a Trackpoint from the previous trackpoint

X = Number of satellites used in the trackpoint fix

D = Distance of the trackpoint from the start of a track (following along the track)

F = Distance of the trackpoint from the finish (end) of a track (following along the track)

P = Distance difference of the trackpoint from the previous trackpoint

N = Name of track to which the trackpoint belongs

E = Name of the trackpoint

If the output has ** after it, then difficulties were encountered in trying to work out the value so probably a default of 0 will be shown.
