It's not actually too hard. N/2 will be the cumulative frequency you're looking for, so a search cursor and a few conditional statements should find your median group. Then just plug that group's range and upper and lower bands into the grouped median formula. I can write it out if you like.

Perhaps try focal statistics on the original DEM to replicate the smoothing function. Then retry.

I guess it could be done by calculating the equations of both lines then solving to see if they are perpendicular and where the would cross, create a point at that intersection and points to line.

I'm assuming you meant this as 20 degrees (i.e 110 degrees)?

I'm not sure. Would probably merge into one FC, planarise, then export them out again. Would work but likely a better way!

Ah I've gotcha. I'm unsure if features in a FC have an extent object. You could turn your FC into a feature layer then export each feature as it's own FC then grab the extents that way? Do everything in memory.

Try ushering and managing the update capability for each feature, log out, log back in, update ownership, log out etc. Can be very buggy. That's all I have, good luck!

Do you plan to use the tool on different tables and field names or is it just to constantly update the one table? If that's the case, just change the path as Dan Patterson has written out for you.

Do you mean it to work as a functioning tool with different data inputs? You need to replace your hard coded stuff with parameters
