I was wondering how track intervals to line computed the distance for a segment.
Track Intervals To Line—Help | ArcGIS for Desktop
successive points in a track will be differentiated by a time and distance difference
successive tracks are differentiated by an end track and restart. Some gps units will end a track after a period of stationarity, and start again, once movement is detected. When connecting tracks it sometimes is an issue when you inadvertantly stop before completion
Hi Dan, Thanks for the reply. I was just wondering how the tool computes the distance once it has the start and the end points for the segments.. Distance is one of the output fields. I don't think it is using the GNSS distance data.
It seems like it is first finding the coordinates of the start point and the end point of a segment and then using these to compute the distance. But I can't find out in the documentation how it is computing it. Is it using 2D distance? Can it do 3D distance? Does it project the coordinates first? Can it take the GPS elevation data and compute 3D distance?
Just wondering if there is more detailed documentation on the distance computations.
Good point... that needs to be fixed in the documentation.
Your task... should decide to accept it... take a couple of your points AND Add Geometry Attributes—Help | ArcGIS for Desktop
because you can report the distances in several ways and satisfy your curiosity and it could be passed on to the documentation people as an example
