track edits

[moldytoe]

Testing out the demo and wonder if I'm missing something.

I see how to split one track into 2. I can select one of those sections. How do you delete one of those sections?

If you are manually editing a track on the map and want to add a point, how do you do that?

If you select a point, I don't see it highlighted on the track properties list. Maybe not a big deal, but I was trying to get rid of a range of trackpoints and tried to do it that way to no avail.

I've been using Arcview 3.2 to do this sort of thing with no issue, but would like to end up with gpx output. Converting an AV shapefile to text and then gpx is ok but there's a lot of extraneous connector lines between track sections that are not in order.

Any hints appreciated.

Hi,

There best way to delete a segment (track) within a file is to open up the properties dialog (right click on the file in the active list).  Hit the 'show points' button to fill the table.  Then identify the range of points by the track number field.  Shift click to grab them all and then delete.

I can't believe that we don't have an option to delete an entire segment after it's selected with the profile/merge tool.  That will be an easy addition to a future version.

You can add points to a track using the insert key.  Select any point on the line and hit insert.  You'll get a point on either side of it that can now be dragged around.

You are right that a selected point isn't highlighted in the track list.  This would be very useful.  Thanks for the suggestion.  If you double click on a track point in the properties it will be selected in the map (and the map centered on it).

Hope that helps.  You've given us some good ideas.

To insert a point as you say doesn't seem to work on an endpoint. I was trying to reconnect a 2 point section that got snipped off in the network creation process. I think adding some points is possible  with the spline process, but something more direct as far as point editing goes might be nice. The arcview model is pretty good - enter vertex edit mode, right click on the line to add, hover and press delete to delete.

Thanks for the reply, I'm sure I'll have more questions!

That's strange, insert should work on an end point -- it just only interpolates one point instead of two.

I'll have to look at how arc adds points.  Thanks.
