Could you post screenshots of your model and particle track tool dialog, please?

May have trouble with mypath backslash. Try mypath = r'C:\input '

What's the error message?

Richard, just curious how to limit merged line segments to those that are touching. Are you referring to the edit merge tool, or Merge geoprocessing tool, or neither?

1.) Dissolve lines using UNSPLIT_LINES 2.) Select the original line segments containing names. 3.) Spatial Join named lines to dissolved lines. You will run into problems where there are T-intersections between differently named lines, but there is no way around it, AFAIK.

As a (possibly fairly accurate) rough estimate, you could simply subtract one surface from the other to get the height difference between pixels. L * W * H is volume, but this assumes your world is made of LEGO blocks the size of your pixels. More accurately, convert your rasters to TINs, then either Surface Volume or Polygon Volume to get the volume for each surface. Subtract the difference. You may also want to look into Extrude Between.

I did look at your data, but I'm really lost on what exactly you're asking. Your line was split into three segments, so it seems you know how to do that. Please try rephrasing your question if you want more help from me.

I don't know about the join method, but you can do the same through copy/paste. Do you need to automate this?

It sounds like you'd want Feature to Line for this (Advanced License required) - the third situation below. Alternatively, since you've already go the intersection points, you could use Split Line at Point (also requires Advanced License).

Agreed. Just adding a link to the TextElement object.

I ultimately want to create a streets layer of all the streets that intersect the polygons. Why not Clip the streets by the polygon layer?

My interpretation is that she's looking for "the construction site farthest from the nearest toxic waste facility," which makes sense.

‎03-18-2015

Not sure I completely understand, but to get the nearest distance between construction and toxic sites, use Near (outputs only nearest features) rather than Generate Near Table (potentially outputs all combinations). Then, sort the feature class by near distance.

actually FID is a numeric field, so a str(i) there would crash the query clause, since its comparing a number to a string. No. " FID = " + str(i) results in a whereclause of " FID = 0 " (desired) not " FID = '0' " (what you predict). Your method may work, but so does mine.
