How to create a series of points along a polyline

Question

I have a series of polylines, these represent various linear landscape features (Roads, hedges,rivers). I need to convert these to a series of points equally spaced (so hedges a point every 2m, a river a point every 5m etc) in order to model them in a 3D programme.

How do I do this - I have done it previous in Arc3, but using 9.3 now and lost.

Thank

Answer 1

You could use ET GeoWizzard. Convert -> Polylines to Points or Polyline -> Split. Not sure if this feature is for free, some are entirely for free, some other features are free to use up to 100 objects.

Edit:

You can also try this code. I did not test this.

It's an out-of-the box feature in version 10 where you would use the Construct Points function on the Editor menu to create points along any line.

I can't think of a way other then doing it progrmatically in version 9.3

Answer 3

Add your polyline feature(shapefile) to arc map, add an empty point (shapefile) both files have to be in same workspace(folder). Then start editor, set point shapefile as target, then select poly line feature using selection tool available with editor toolbar, then click editor drop down menu, choose divide, then provide your required interval in " Place points separated by every .... Units). New point features will be created along polyline at specified interval

Tested in arc gis 9.1 , 9.3

I haven't used it myself, but I believe linear referencing would be the best way to achive what you want. http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/What_is_linear_referencing/003900000001000000/
