profile graph in ArcGIS pro 2.0

junewong

I am using ArcGIS pro 2.0 with 3D analyst extension, and i have created a tin layer including elevation data.

But i have no idea why the profile graph is showing zero ? The blue profile line is created by ready-to-use tools "Profile"

When i was using ArcMap, profile can be created by using 3D analyst toolbar.

Thanks.

As Dan already mentioned, this will require you to run Interpolate Shape—Help | ArcGIS Desktop first and then create the profile graph

Profile graph.... doesn't it require 3D line geometry?

Thanks!

And the next question is how can i export the graph to excel?

the export icon as shown is only for images.

and the attribute table only contains shape_length.

did i miss any steps? i am new to Arcgis Pro.

Many thanks again!

FeatureVerticestoPoints with an Add Geometry Attributes to get the coordinates then

Table to excel depending on your license levels of course.

or FeatureClassToNumPyArray then standard numpy savetxt to get it to a csv format which allows for x, y, z to be read in

Hello Dan,

after working with Feature vertices to points, the attribute table is like this,

am i working right?

thanks.

you now have the points... at this point you can proceed with

the Add Geometry attributes to get the point information to add X, Y and Z values
and calculate the cumulative distance using the field calculator on a new double field. (or in a secondary program)

If you add a field called SeqDist type double, appropriate precision and scale, set your program to python parser use the below and you can now graph distance versus the Z value

Thanks Dan. i did it.

junewong

and i have one more question, as i just have about 10 points along a 100m long wide, can i have more points?

many thanks!

DanPatterson_Retired

June... you should mark the question answer with the answer that worked.

As for the 10 points issue... since it only took 10 points to produce the line, it has captured all the inflection point, so adding more won't add anything.

If you insist on doing this anyway, you will have to densify the polyline (there is a Geodetic Densify in the same area)

Explode to points as before, repeat the calculations and redo the length.

Sooooo, if the extra points won't improve the graph, I see little point
