Convertion from raster to polygon

Question asked by geonetadmin on Sep 28, 2010
Original User: ggarcia78


I am converting a raster file into a polygon, but there is an offset which is not consistent as you can see in the figures I am attaching... I already did the same process several times, but is always happening the same offset, I don't know what to do. I will appreciate very much your help on this... or even giving to  me an alternative to get the same result without this offset.
I am attaching some figures, so you can see that the resulting polygon is not going in between the raster pixels...Somebody knows actually the details of how ArcGis does this type of conversion?

Best regards,
