Raster to Polygon tool fails to convert a raster

Thiago_Nascimento

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:

1. Open the ArcMap (tested on version 10.8.0.12790);
2. Add an elevation raster to the TOC. For example, the 'EGM2008_subset.tif', available at https://www.arcgis.com/home/item.html?id=042f87ce25e34bffa244cf306dcb7aae;
3. Classify the raster's symbology in 3 classes;
4. From the layer's context menu, choose [Data > Export Data];
5. Check the option 'Use renderer' and proceed;
6. When prompted 'Would you like to add the exported data to the map as a layer?', choose 'Yes';
7. Open the Toolbox and use the tool [Convertion Tools/From Raster/Raster to Polygon];
8. Set the previously converted raster as the input raster and proceed;
9. The resulting Shapefile output comprises only the boundary of the raster

Workarounds:

1.  
   1. After exporting the raster, when prompted to add the exported data to the map (step 6), choose 'No' and then add the raster manualy after this.
   2. Proceed with the conversion
2.  
   1. After exporting the raster, when prompted to add the exported data to the map, choose 'Yes'.
   2. remove the raster's layer from the TOC, then undo this action, so that the layer is added again.
   3. Proceed with conversion

Hi,

First convert yout raster to Int and tha  use tbe Int raster as a input raster of Raster to polygon tool.

Hope this works.

Thanks
