Hi I have some long linear polygons that I'd rather store as lines but I'm not sure how best to do this. Ideally I'd have a line goiung through the centre of the polygon lenthways. I have two ideas of how to do this but I'm not sure how to implement them or to what extent they're possible. Perhaps theres already a tool out there that does this?

option one: 1. convert polygon to points at verteces 2. identify the two points furthest apart in each feature. I can do this in point distance but I'm not sure how to automate it 3. mask the area outside the polygone 4. run a cost path between the two points

optoin two: 1. convert polygon to points at verteces 2. Create theissen polygons arouns the points 3.(somehow) save the line along the middle between the theissen polygons?

Does anyone know how I can make either of these methods work or if there is an easier method. My pythons weak so I was going to try it in model builder but if I needs python I can give it a go

Download the ET Geowizards toolbox (Free) and use the createCenterlines tool. I think that should do the trick.

Highly Recommend GeoWizards - has saved many, many hours in ArcGIS/Geoprocessing work. –  Mapperz Dec 2 '13 at 15:14
