Splitting a polyline shapefile using a fishnet shapefile?

[AlexanderPeace]

Hi,

I have a polyline shapefile that I would like to split into boxes of equal size. I have been told the best way to do this is to use a fishnet grid, is this the best way?

At the moment I have a fishnet polygon shapefile and I am attempting to use the 'Split (Analysis)' tool in Arc Map 10 but I get an error:

"Field Shape not of type TEXT"

Any help appreciated,

Regards,

Alex

Are you setting the Shape field to be the Split Field? I think this parameter needs to be a field containing a unique ID, so a numeric field like ObjectID or FID.

Hi Duncan,

Thanks for your help. Yes I am setting the Shapefile generated by the fishnet as the split field. What do you keen by a field containing a unique ID? How can I generate one of these?

Thanks,

Alex

The third parameter of the split tool, it should be a field that holds a unique ID such as the FID field.

Ok, so how would I create something which contain an appropriate field for this purpose?

Thanks,

Alex

Well for starters just use the FID field, that's unique?

Got it!! Thanks!

The key to this if anybody else tries is to make sure that the Field you are using to split is set to 'Text'

Hi

Despite being slightly flamed by Duncan H. I can offer:

Except you'll need to make a minimum bounding rectangle by width from your polyline first.
