Converting Raster to Polygons With Floating Raster Points

[BradyHay]

Hi all,

I'm in the process of trying to utilize ArcToolbox to convert a raster image into polygons for use in CAD. Unfortunately the raster to polygon tool won't work as the raster image contains floating raster points (32 bit). I found a potential solution of utilizing the raster calculator to convert a floating type raster to a polygon feature class but It's not under my current license (using ArcMap). I'm wondering if there's a different solution with the version I have or if I'm simply out of luck. Thanks in advance!

how many decimal places do you need?  1? 2?

int(!yourraster! * 10)  or int(!yourraster! * 100) 

just remember to scale back the attributes in the table if needed

Hi Dan,

I appreciate the reply! I checked the editor options and it looks like 3 decimal places so I'm assuming I can substitute 100 as the value. I'm new to ArcGIS, is this a command to be entered into python?

Also I don't have an attribute table associated with the raster image.

If you need 3 decimal places  then * 1000  before taking the integer representation.

You won't have a raster attribute table because it is floating point and only integer rasters have a table.

Appreciate the replies Dan. Unfortunately I'm not currently licensed to use the raster calculator (initial image). I'll have to discuss our current licensing internally in order to complete the task.
