Convert rasterized line back into polygon with segment IDs in order?

JoshuaStevens — Wed, 05 Jan 2011 19:29:11 GMT

Hello,

I've ran into bit of trouble with some conversions. Basically, I am working with street data that is in polyline format.

I converted each street to raster so that I could do some other calculations. I then end up with a raster of the street with the values I want.

When I convert the raster to polygon I want the IDs of my value field to be in sequential order that follows the roadway. This happens in North-South streets (I'm assuming raster -> polygon conversion occurs top to bottom). It fails in other cases.

Does anyone have any suggestions how I might get around this?

Any help or advice is greatly appreciated!

Thanks in advance.

The only way to do this would be to link your original line features to the raster by a common identifier with Add Join or Join Field and copy your results over.

If you have a raster with the IDs and your values are gone, you can use the Zonal Statistics or Combine function on the raster side to get your IDs and derived values in the same table so you can do the join.
