Are you saying that option 1 isn't equal to option 2? Scenario : Bus route through points 1 to 4. 2 people get on the bus at point 1 to go to 4. At 3, 20 people get on the bus but they want to go back to 2. So the "greater good" is that the bus turns around and returns to 2. That's not a bus service that's a taxi....

Isn't 1 == 2? Maybe not but I am struggling to imagine an example.

And, in the case of external files like tiff or jpeg, you may have to use the normal win file explorer to delete any associated files like worldfiles - tfw, and any aux or xml.

Ben, my version is 10.3.1, but I am pretty sure it's the same in 10.2... Right click on the dataset in Catalog. Scoot down to the Spatial Reference part, click edit to bring up the spatial reference properties page. Click the little pull-down next to the world icon at the top. Click Clear.

Sorry, files??? Is this spatial, well at least the roadway center lines? If you have roadway centerlines as a feature class with measures (PolylineM), then you can join the signs table to it by creating route events. This problem has nothing to do with union or other geometry overlay operations.

Couldn't you do just an intersect or union function on the lines and the polys, then process the output to compute the result.

Well Joshua has effectively given you the answer. Why not implement something like this : with arcpy.da.UpdateCursor(fc, ["SHAPE@"]) as Cur:
for row in Cur:
origGeom = row[0]
row[0] = origGeom.union(origGeom)
Cur.updateRow(row)

Well it will certainly be do-able but... One Polygon or many? How do you want this to be reported ie adding a field to the lines stating how much lies within... Is your data projected to a planar system?

Can you please give us a little bit more detail on what you are trying to achieve. I don't quite understand your question.

I have seen in the past in Arc where a process apparently doesn't complete but it actually has. If there is nothing going on in Task manager I would kill the application, then have a look. But 100mill edges, ???.....

If you have another column which contains the "001", "002" or perhaps just the number, you could probably just do a concatenation with the field calculator. If you havn't got this second field, what governs the "001", "002" part connecting to "Grid1" etc?

This is the difference between "defining" the projection or "projecting" the data to another coordinate system. First, when you defined this data as GCS_WGS84, are you absolutely sure that is indeed the correct definition for this data. Post the data extents from the layer properties page here. Do those numbers look like decimal degrees? ie are they fairly small? If they are large ie >+thousands, then the original data is not in degrees. Once you have established what the original reference system is, then you can take the next step and project it to a reference system appropriate for your analysis.

When exporting from the data frame, if a geographic transformation has been selected, then the output will correctly reflect that. I am very sure that the underlying projection / transformation algorithms are the same, whether using the project tool, data frame export or export into a feature dataset.

What is the format of the imagery files - tiff, fgdb... Pyramids create subsampled data so that the image draw quicker when zoomed out. How is the image "degraded" and what does it look like when zoomed into, say <1:2000. If you are printing these, what is your output dpi?
