Convert Lines in discretized polygons

Ryan_Conway — Sun, 19 Oct 2014 02:13:20 GMT

Hello,

Quick disclaimer: I am a geologic engineering student that has been placed in charge of the GIS portion of a research project(not sure why) and I do not have very much experience.

I need to turn a road layer into discrete polygons 1m in length. I am trying to overlay visual pothole/road failure data, GPR data, and other data to make statistical comparisons. I know how to make the lines(the roads) into polygons, but can not figure out how to cut them up into little bits automatically.

Any help would be appreciated.

Splitting a polyline in edit mode then buffer...but their has got to be an easier way because I am guessing you are going to say that "I have lots of lines to do"

Thanks that is definitely a good starting point. I dissolved all the poly lines into one line. Then, used the split line feature. However, you are limited to 999 equal pieces. I want 1m cuts which would mean I would have to cut the roads first into km pieces and then meter pieces. This get me going on little sample section though thank you.

If I find a better solution I will post!

You can check out XTools pro (it has a one month trial period, I think). With that you can use convert features to points and generate points at 1m intervals on your lines. Then use them to cut your line. Then buffer your line to get polygons.

Thanks I'll give that a shot.

Do you know if there is a way to buffer points into rectangles rather than into circles?

Thanks!

There are some square buffer tools on resources.arcgis.com (hard to find stuff) which can be used for point features. For lines, the buffer tool allows for squared ends if you have a license higher than the Basic one
