I am using qis to edit tracks of a GPS file. Usually I want to delete
extraneous tracks from the layer.
I import the layer as a vector gpx file. If I import the gpx file and it
has more than one track (<trk> </trk>) then the indiviual points will
not show up when I open the attribute table. I just get 2 elements which
are the 2 tracks composed each of multiple segments. If I put all the
trackpoints in one track in one file, then I can see the points in the
attribute table.
To edit the gpx file, I have been opening it in a text editor and making
changes. Then I will see how the display is affected. Sometimes I can
update it by turning on and off the vector layer. I read on here that
ctlr-r will refresh the screen. Both do not always work. This last
time I had to exit qgis and restart it to see my updates.
I am using qis 1.7.4-Wroclaw, gdal/ogr version 1.90, postgresql client
9.0.3, spatialite 2.40, qwt 5.2.2, qt 4.7.1
