How To: Convert a floating type raster to a polygon feature class and retain the decimal values
The Raster to Polygon tool can only process integer input rasters. Hence, a floating type raster must be converted to an integer type raster before using the tool.
The following workflow requires a Spatial Analyst license. The Int tool mentioned in this article exists in both the Spatial Analyst and 3D Analyst toolsets.
The instructions provided describe how to convert a floating type raster to a polygon feature class and retain the decimal values.
Using the Raster Calculator tool, multiply the raster with a multiple of 10 required to remove the decimal values. For example, multiply a raster by 1000 if the raster values contain three decimal places, and by 100 if the values contain two decimal places.
