[ATTACH=CONFIG]33230[/ATTACH]I'm trying to iteratively convert a ton (~300) thresholded rasters (integer value 0 or 1) into shapefiles. I've attached a picture of my model. The model runs through rasters, and does write shapefile output, but when I compare the resultant shapefiles to the rasters, they are completely off. Initially, I was writing the intermediate rasters to memory, since I only need shapefiles where the original raster value = 1. In both cases, the output is apparently unrelated to the "parent" raster file, and I'm not sure what the problem is.One thing I've noticed is that the raster to polygon geoprocess is running suspiciously rapidly, compared to running it as a one-off tool in arcMap. Incidentally, the output I get from doing the same thing manually in arcMap makes sense.I'm including converted Python code below, in case that would help anyone think about this.# -*- coding: utf-8 -*-
