arcgis-desktopdistancegeometry-conversionpointpolyline-creation
I want to convert these points to lines, however they are not sorted sequentially along a line (by ID or FID), i.e. the converted lines zig-zag across the obvious trail of points.
How can I join these point trails based on proximity to points?
I don't have access to the Near (Analysis) tool, which I thought might help me move froward.
Well I couldn't work out how to tie the original attributes back to the lines in ArcGIS. But I ended up getting the job done in R using the AdehabitatLT package. The instruction manual can be found here: http://cran.r-project.org/web/packages/adehabitatLT/vignettes/adehabitatLT.pdf
Here are the steps:
The trajectory lines created using this method for viewing in ArcGIS still don't have the original fields in the attribute table and are just one line per animal. However, the dataframe export into excel gives me the information I need to do the analyses, so it works well enough.
It would be neater if we had this info in the attribute table for each line. But it gets the job done.
I can post the script if anyone is interested.
I'm still interested to hear if I can do this in ArcGIS.

The simplest way is to use the points to create the line. To do this in QGIS use the Points2One plugin. Install this plugin (available via Plugins > Manage and install plugins) and follow the dialog to create a line from your points.
If you have multiple lines, then make sure your points data has a suitable ID field to identify the lines they belong to.
Alternatively you can use v.build.polylines in GRASS (available through QGIS) or the SAGA GIS tool Convert points to line(s) Available through the Processing Toolbox (Ctrl+Shift+T).
