Tom,
I know you're doing what you can, but for now look at my attachments again:
Forget that I used another software to create a Points layer of boundary
points (where the polyline intersects the polygon boundary).
The illustrations show the differences between what I have right now (a
polyline layer with a number of segments with individual measurement
values) and what I need (a polyline layer of one segment length.
For now, I have used Linear Referencing tools but I am only getting the
current begin and end points of each segment; I need to have the values
based on where the polyline intersects the polygon boundary---ideally with
an automated procedure.
I essentially have a 3 part procedure for a segments layer that has 2500
segments:
1) A polyline feature that has segments with measurements. I need to
aggregate the segments into one segment with a total length of X?
2) Break the newly aggregated polyline find the (new) point measures for
where the new polyline segment intersects the boundary of the polygon .
3) My points layer database needs to have fields indicating the prior
segment's Begin Point and the End point values.
*****************
I have tried the tools in Linear Referencing, but haven't been able to find
the tool/tools that work. For example, the one tool that aggregates the
segments doesn't give me the fields I need--Begin and End point measures
for the segments, just the ID fields for the polylines (??).
Hope this helps.
