Functions for shifting layer data up/down and left/right

Functions for shifting layer data up/down and left/right

[kpurdon]

Load from param spreadsheet (don't worry about this, well write run wrappers after).

opsShiftGpsTime(sys,param)

param.properties.location
param.properties.season_name
param.properties.segment_name= string ('20110601_01')
param.properties.offset = float (gps time)

opsGetLayerPoints for segment
create new gps_time vector from layerPoints (shift by offset)
interpolate (inter1,PCHIP) layerpoints values onto new gps_time vector
call opsCreateLayerPoints (same point path id, new layer values)

opsShiftTwtt(segmentName,offset)
segmentName = string ('20110601_01')
offset = float (gps time)

opsGetLayerPoints for segment
shift layerPoints value up/down
call opsCreateLayerPoints (same point path id, new layer values)

[kpurdon]

opsShiftTwtt (done) and opsShiftGpsTime (in progress) are in the toolbox.

@wliu58i5ki
For opsShiftGpsTime:

1. Get layer data from database - use opsGetLayerPoints

2. create shifted gps times (gps_time + offset)

3. new_twtt = interp1(shifted_gps, twtt, gps_time)

4. Re-insert layer data into database - use opsCreateLayerPoints

Need to delete layer points for the segment before reinserting.

Looks like create layer points will delete old layer points automatically

It only deletes points that are in its way… there will be some points that need to be deleted and not inserted (e.g. gaps will be shifted too).

@jpaden I have committed, if there is something wrong, please let me know.

[jpaden]

Did you test it out on your textbox with data that you have loaded?

Yes, I did. I used ‘2012_Antarctica_DC8’ data.
