split by attribute

TilottamaGhosh — Fri, 04 Nov 2011 10:29:17 GMT

Hi,

Is there a way of splitting a shapefile (point, line or polygon) on the basis of a particular field in the attribute table? I have a point shapefile which shows Points of Interests on the basis of different categories. I want to split the shapefile on the basis of those categories, so that I get separate point shapefile for each of those categories. Is there an inbuilt tool in ArcGIS 10 for that? The split tool won't help as it does it on the basis of another feature class, and that is not what I am looking for. I found this tool through my search online http://www.umesc.usgs.gov/management/dss/split_by_attribute_tool.html, but couldn't make it work. I am looking for a tool like this. Any kind of help or suggestion will be greatly appreciated.

Thanks in advance,

Tilo

Here is a Python script to do just that...

In ModelBuilder try Iterate Feature Selection or Iterate Row Selection iterators.

Hi,

Thanks so much for all your responses. I downloaded the tool from the ArcGIS resource gallery that Dan suggested and it worked perfectly. However, I will also try the methods suggested by gabrisch and Shitij. Thanks a bunch!

Thanks,

Tilo

Hi Dan,

Do you remember what this tool was? Since the website was updated the link no longer works.

Thanks,

Selecting by attribute value and exporting to a new feature class wont work?

When I was in college programmable calculators were just hitting the scene. A group of us approached our calculus professor and asked if we could use them in class. He said : " Sure. But you still need to learn the calculus. Don't become a slave to the machine..." Man, that guy was cool.

Translated: you still need to know data base manipulation, geographic principles and cartography. Thinking and figuring out a solution are still valuable skills all these years later.....

Hi Dan. Thank you for a great tool. I've used it a couple of times before, but now it runs into a problem that i have difficulties with solving.

If you have time and would like to help I've pasted the error message below.

GST_LINTXT is being queried for unique values.

Failed script SplitLayerByAttributes...

Traceback (most recent call last):

File "M:\HAL\TeamNIS\Arbejdsdata\ANDEH\CoastlineL\Tools\SplitLayerByAttributes.py", line 121, in <module>

aString = aString + " " + str(aVal)

UnicodeEncodeError: 'ascii' codec can't encode character u'\xe5' in position 7: ordinal not in range(128)

Failed to execute (Split Layer By Attributes).

Failed at Tue Jul 21 15:30:10 2015 (Elapsed Time: 0,95 seconds)

Is it my attributes in the column GST_LINTXT that might contain values inapplicable for this tool. The format is string.

Best regards
