I have a huge dataset with flowpaths containing a catchment area for each line. The attribute table has ~ 780.000 rows, and thereby 780.000 features in the mapwindow.



Is it possible by using a field to merge the data in intervals, so you get a multi-part feature instead?



For instance merge all the features so those with a catchment area of 1-10.000 become one, from 10.001-20.000, 20.001-30000 and so on? The interval doesn't have to be 10.000 but can be another value.



I was messing around with the dissolve feature, but other than doing a manual population of a field and then dissolving by that attribute, I couldn't find another way to do it.



Basically I want what the symbology window does, but I want to do it to the dataset.



I have ArcGIS Desktop 10.5.1 with the Advanced License.

Create a new field of intervals and assign an interval to each record. Then dissolve by interval field. This can be done with field calculator and many if-elif-elses or you can use pandas module (which is included in ArcGIS 10.5) and pandas.cut:




Use cut when you need to segment and sort data values into bins




Add a text field named Intervalfield, modify indicated lines and execute code in the python window of ArcMap. Then Dissolve by Intervalfield. If you want to use some other areafield instead of shapearea, replace SHAPE@AREA with the name of your field:



import pandas as pd
import arcpy

fc = r'C:data.gdbfeatureclass' #Change to match your data
bins = [-1,10,20,30,40,50,9999] #Add/remove bins

df = pd.DataFrame.from_records(data=arcpy.da.SearchCursor(fc,['OID@','SHAPE@AREA']),columns=['OID','Area'])
df['Interval'] = pd.cut(df['Area'], bins=bins).astype(str)

intervaldictionary = dict(zip(df.OID,df.Interval))

with arcpy.da.UpdateCursor(fc,['OID@','Intervalfield']) as cursor:
 for row in cursor:
 if row[0] in intervaldictionary:
 row[1] = intervaldictionary[row[0]]
 else:
 row[1] = 'Unknown interval'
 cursor.updateRow(row)


After code you will have output below, then dissolve.

    This works perfectly, thank you. As a bonus question out of curiosity and it isn't required as I can use this fine, but is it possible to put this into a toolbox, where you can choose your input file and intervals instead of "hardcoding" it?

One-line joke

A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
