[Marble-devel] Plotting custom position data on MarbleWidget (viaPositionProviderPlugin?)[Scanned]

Mon Apr 2 11:20:38 UTC 2012

Hello Konrad

Thanks for responding to my question. Your solution has raised a number
of other questions in my mind. Again any help you can provide would be
gratefully received.

*	I'm not quite sure how I should generate a route from my
position points (PositionProvider). Do you have any examples I could
look at?
*	How can I produce a route with all my GPS waypoints?
*	The track I'm trying to plot is cross-country and so will not
follow any road or path features of the map, will this cause a problem
with the route manager?
*	Will the performance of loading a route file be enough to cope
with 1 position report every second over a period of up to 7 days (i.e.
604,800 or six hundred thousand points)?

Regards

Ian

Hi Ian,

>>I have tried implementing my own PositionProviderPlugin 

try the positionprovider/FileReade plugin,

this is a Gps simulation plugin.

First use marble/routing functionality to create

a route, export the route to:

..\mapdata\routing\route.kml .

The FileReader plugin imports the placemarks from the route.kml,

see if this works.

br, konrad

MarbleWidget (viaPositionProviderPlugin?)

	Hello. I would like to be able to plot a track of position data
(from a custom GPS data source) onto a map displayed in MarbleWidget.
Ideally I would like the user to be able to hover over any point on the
track and get a display of the data (time, position, etc) at that point?

	Could anyone let me know the best way to do this?

	I have tried implementing my own PositionProviderPlugin and
setting this visible in the MarbleWidget:

	Marble::MarbleModel* model = this->model();

	model->positionTracking()->setPositionProviderPlugin( new
Marble::CustomPositionProvider() );

	model->positionTracking()->setTrackVisible( true );

	However when I run this, the widget only displays a small
segment (say 30 degrees) of the map centred at the current position in
the direction given by the PositionProviderPlugin with the rest of the
widget remaining undrawn.

	I am using a QT only build of the MarbleWidget (version 1.2)
build on Windows using Visual Studio 2010

	Any assistance would be gratefully appreciated.
