The tool generates only the raster's boundary when it uses as input a raster that was automatically (after user confirmation) added to the TOC resulting from the Export Raster Data.
Steps to reproduce the failure:
First convert yout raster to Int and tha use tbe Int raster as a input raster of Raster to polygon tool.
Hope this works.
This is not really a question, just a bug report and a workaround, but thanks for your reply.
Maybe I should post it somewhere else, just don't know where.
Thanks. I was hoping to post it publicly to let others know about the issue and related solution.
Have you reproduced all the steps as described? The bug should occur when using Raster to Polygon after having used Export Data on the same session. It is a very specific case and easy to circumvent, but very annoying. It seems that ArcMap fails to properly load the raster (resulting from the previous operation), so the next operation works as if it received a blank raster.
