Editing and splitting of activities/graphs/tracks explained

Postby CHnuschti » Fri May 29, 2009 9:02 am

This section explains how to split activities and how to edit data and GPS (location) tracks

MLC= Mouse left click
DMLC= Double mouse left click
MRC= Mouse right click

In the Daily Activity view, basic SportTracks allows to split activities, edit existing data tracks (such as heartrate etc.), but also allows to modify existing GPS tracks (location by coordinates) by moving the location of one or more points. Splitting and editing of data tracks is done in each a seperate window, while editing GPS (locations) is done in the route view.

Editing GPS or data tracks usually is used to remove/correct few obviously faulty spikes/locations, but can also be the favorite tool for meticolous personalities.

0) Preliminary remarks
SportTracks handles tracks with the time (="timestamp", for example YYYY-MM-DD-HH:MM:SS) as reference point. Points of time are the nodes of the frame of a track, everything else (location, altitude, heartrate etc.) is attached to these nodes. You will be able to modify everything, except the points of time. You may move the points of time, but they will be moved all together. Deleting a point of time will have no effect on the time of the adjacent points of time. Time is somehow the constant of the tracks.

You may possibly mess up your activity into an irreversible condition in course of your editing. Don't worry, there are 3 possible remedies:
a) When SportTracks directly downloads a record from a device, it writes an own file (*.fitlog) for each activity, containing the original, raw, detailed, unaltered data "as delivered". See storage FAQ for common locations of storage.
Over the Daily Activity menu, just remove your messed up activity with MLC on the "Remove Activity" entry and reimport/restore it by choosing the corresponding *.fitlog file with MLC on the "Import" entry.
b) Quit SportTracks without saving the logbook. Your messed editing won't be saved.
c) If still available in your device, you just can import the activity directly from the device again. Remove the messed up activity first according to a).

Question:

How do I split activities?

Answer:

Splitting activities

1) Go to daily activity view, select a day/activity in the calendar or in the list on top with MLC.
2) In the daily activity menu, select "Edit activity" and then "Split" with MLC.
Image

3) A window "Split Activity" will open. Now enter the split point either by defining Time or Distance, or MLC and hold the slider, then move it to the split point. Modifying any of the editable fields or moving the slider will instantly actualize everything else, so you have all informations you need. Check/uncheck the option box "Remove empty time between activities". If checked, this will remove the time segment (including distance and corresponding values) between the two adjacent points of time. If unchecked, end and start of both splits will be the same point. The field is prefilled with the actual time difference.
4) You can use the option box "Remove empty time between activities" also to remove an entire segment (and the corresponding distance and values) within your activity. Check the box with MLC, then enter the time duration of the segment to be excluded in the field. On the slider, a grey bar will appear, it represents the segment which will be removed. You still can move the slider with MLC and hold, the bar will move with the slider. In the field, only positive time values are accepted, so move the slider to the point, where the segment to be excluded shall start. The informations on bottom are still displayed accordingly.
5) MLC "OK" to apply. Each split will now have an own activity entry in the lists. Note: there is NO "undo" for this operation, splitting is not reversible.

Important note

The total duration of the activity shown in the split menu is also determined by your pause setting (A) as defined and explained in this FAQ point 4). Contrary to this, pause setting (B) according to the FAQ point 5) has no influence, watch pauses are never included in the total time of the split menu.
If you have setting (A) off/unchecked (=> pauses are not included in total time), your set split point might lead to unexpected results, having the activity splitted slightly put off. This can occour if your split point is in proximity of such pauses.

The following handling is recommended: Prior to split an activity, go into route panel and determine your split point along the route. Over the setting Settings=>Display=>Routes=>Details, include "Time elapsed" in the values to be displayed in the route view. The pause settings as described above do determine the "Time elapsed" exactly the same way as they do determine the "Time" in the split menu.
Now pick your split point in the route view (select it with mouse left click), take note of its elapsed time, then enter this time into the "Time" field of the split menu. This should assure your activity is indeed splitted where you intended.

Question:

How do I edit data tracks?

Answer:

Editing data tracks

6) Go to daily activity view, select a day/activity in the calendar or in the list on top with MLC.
7) In the daily activity menu, select "Edit activity" and then "Data Track" with MLC.
Image


8 ) A window "Edit Data Tracks" will open. Now select which data track you want to edit with MLC, for example Heartrate.
Image


9) Your data track to be edited will be displayed. The graph is always displayed over time and will always include also the "stopped" time and "watch pauses" "covered" by settings (A) AND (B) of the pause settings (points 4) & 5)). Handling of the graphs what concerns moving, zooming, selection of a single point or a part of the graph with several points etc. is same as explained in the graphs FAQ. All the points displayed along the graph can be edited. You very likely have to zoom in for an easier editing.
Additional features a), b), c), d), e), f), g) are available, see details below.
Important: You may see your changes in course of your editing in this window, but saving/applying to the logbook, lists etc. will not happen until you have confirmed this window with MLC on "OK", so you still can cancel.
Image


10) Standard editing: MLC a point or select a section of the graph. Then move mouse pointer over any selected point. The pointer will change into a double arrow. Now MLC and hold, then move up/down to wished position and drop. All points will be moved by the same amount and connected to both next nonselected, adjacent points.
Image


11) Feature a) Add time (and values) OR single value to the data track
MLC icon, a window "Add" will open. Now either choose to add an entire section or a single value to the data track with MLC. Enter your values in the available fields.
12) Adding a single value will connect the added value to adjacent values.
13) If you choose to add an entire section defined by time duration, you can place it wherever you want, append it at begin or end of the existing data track, or place it in between. Set values in the fields accordingly.
Image


14) Feature b) Remove one or more points from data track
Select a point or select a group of points by selecting a section of the graph., then MLC the "Remove"-icon. Points will be deleted. If single point, both nonselected, adjacent points will be connected. If a group of points, both selected boundary points will be connected.
Image


15) Feature c) Remove data outside a range of your choose
The radical cure, deletes ALL points of hole data track outside your defined range. Useful to get rid of unwanted spikes and the like.
MLC icon, a window will open. Select the type of range ("...above"/"...below") by checking/unchecking the boxes with MLC, then define the "cutoff" values, MLC "OK" to apply.
Note: pay attention when applying a "cutoff" of type "...below"; while it can wipe out unwanted "minimum" spikes, it might also remove hole sections (probably) in the begin/end of a data track. See picture, an entire section of approx. 2min at begin is removed.
Image


16) Feature d) Undo performed operation.
Note: this will undo ALL your previous editing steps and bring the data track back to its original shape as it was before you opened the "Edit Data Tracks" window.

17) Feature e) & f) Import/Export data track
Usually used for data tracks, where for example you have the GPS track (location), but your data track comes from a seperate device.

Note: the process of joining two or more data tracks very likely is also possible via the standard import process. This might be a much easier way than the procedure described below.
The import feature of SportTracks allows also to "update" an existing activity, this is the way to go. See this FAQ entry for details.

Import and export will require/be "comma separated values" (*.csv). So for import prepare your files as such. Format first value time in seconds, second value unit of your data track, which must correspond to your unit choice in the settings of SportTracks. First line "Seconds;Value" MUST be included.
Note: You must know what you do here, you can easily mess up your data tracks as hole, for example in having different values types that should correspond, which however are not assigned to the same points of time.
Image

18 ) MLC "Import" icon, in file browser change extension type if your data comes as *.txt or similar. Pick your file and confirm. Your imported data track will be displayed.
Image
Image


19) Feature g) Change start time
Change start time by entering your time/date in the field "Start Time:" or MLC on the arrows to move forth/back the point of time. The field "Duration:" can not be edited. Details coming soon.

Question:

How do I edit GPS (location) tracks?

Answer:

20) Go to daily activity view, select a day/activity in the calendar or in the list on top with MLC.
21) Now in the daily activity view, go to the route view/window bottom right. Here, top left MLC "Explore"-icon and change to "Edit". Track will be editable now.
Image


22) For better visibility of your editing/track, you may want to have some additional display help. Go to Settings=>Display=>Routes and check the "Show GPS points:" box with MLC. Optionally, change size and/or color of these markers with MLC in the dropdown menu "Size:" and "Color".
Image


Pointers and graphic help, addition of GPS points "inside" and "outside" of the existing track
"GPS points" are the points of time containing a location (=coordinates) which are visualizable in the route window of the daily activity view according to 22). "Points" in the following descriptions mean such "GPS points".

23) Move mouse pointer over a connection line between 2 points: it will change into a "+"-icon. This allows you to add a point in between. MLC it, a GPS point will be added.
24) Move mouse pointer over a point. It will change into a square icon with 4 arrows (="moving"-icon). This allows you to move this point with MLC and hold, it will stay connected with both adjacent points.
Image Image


25) Move mouse pointer over begin or end of the track. You will notice a graphic help to handle the addition of GPS points "outside" the given track: a point next to begin/end and an arrow in between. These 2 boundary points can NOT be moved, also are not part of the existing track, they are displayed only in the "edit" view. Their function is to enable the addition of GPS points.
Move mouse pointer over the boundary point, it will change into a "+"-icon. MLC it, only now a "real" GPS point is added and attached to the track, after this you can move this point and bring it into wished position. Faster alternative to create and move a new GPS point at once: MLC the "+"-icon and hold, then move to the whished position and drop in a single process.
26) The graphic help will be moved forward to enable a further additon, and so on.
Image Image


27) Selection of points
- Single point selection: move mouse pointer over point and MLC it.
- Selection of a group of points: MLC a point, then push Ctrl key and hold, and continue selection of (also nonadjacent) points with MLC.
Alternative: MLC the "Select"-icon top left (blue square), then move the mouse pointer into the route view. Pointer changes into a cross. MLC and hold, then drag a rectangle over the points/track segment. You can even expand this selection with more nonadjacent points. Push Ctrl key and hold, MLC the "Select"-icon again, move into the route view and drag a rectangle again. The selected points will be added to the previous selection. And so on.

To deselect points, just MLC somewhere else.
Note: you still can pan, once points are selected. Move mouse pointer outside the track, then MLC and hold. Pointer changes into a hand. Pan your sector, the previous selection is kept. Only MLC without hold will deselect the selection.
Image


28 ) Deleting points
Once you have selected one or more points, MLC the "Delete"-icon (red cross) on top left, they will be deleted and the connection line be drawn between the next 2 adjacent, nonselected points.
Pan as described in 27) is possible also here.
Note: there is NO undo function, no way back!
Image


29) Moving points
Once you have selected one or more points, move the mouse pointer over any selected point, it will change into the "moving"-icon. MLC it and hold, then move and drop. All selected points will be moved by the same distance. The "Select"-icon must be unchecked to enable the "moving"-icon to appear.
Pan as described in 27) is possible also here.
Note: also here, no undo function, but you still can move "back" manually.
Picture shows moving a selection of 2 groups of nonadjacent points for illustrative purpose, this is not necessarily useful.

Question:

What effects does all this editing have?

Answer:

Effects of editing data/GPS tracks on calculated values
Your edited data/GPS tracks will be regarded as the valid ones and in principle affect values in lists and summaries.

The following statements below are valid for these conditions:
a) You did not insert or attach a time segment as explained in 11) and 13)
b) You did not insert a value with a point of time "outside" the existing track as explained in 11) and 12)
c) You did not insert/attach a GPS point "outside" the existing track as explained in 25) and 26)
d) You did not delete first and/or last point of a data OR GPS track

Editing data tracks:
- Editing an existing data track will change your average (for elevation: total ascent/descent) and possibly minimum/maximum values, but ONLY of the edited value.

Editing GPS tracks (location):
- Moving/deleting any point will change the total distance. Since you can not change the time of such points, this will affect only speed/pace averages, possibly max./min. speeds/paces, but NOT all other averages.


As soon you perform operations as described in a), b), c) , d) above in this post, you may get unexpected effects on distance, time and averages.

Question:

Are there any plugins or tools available offering additional features of editing?

Answer:

Related plugins and tools

After Import Plugin allows you to process the data tracks to optimize and remove spikes, it can automatically do this when you import activities.
http://sporttracks-plugins.com/SportTra ... ocId673233

MiscPlugin has some limited support for certain import too:
