Convert data type in Euclidean distance calculation script

[AndrewOrr]

Hi all,
I have a python script where I'm trying to perform a Euclidean distance on a feature class to generate a raster. The map units are meters so it outputs the cell size in meters as an integer format. I want it in miles, so I multiply by a constant to convert to miles. This, however, does not change the integer data format to a floating point. Is there any way to specify or convert the output Euclidean distance data format to FP so I can get an output as FP?

Here is the line of code I'm using in the script:

OutEucDistance = (EucDistance(src_layer, "", resolution, "")*0.000621371192)

Thanks for the help,
-Andy

according to the help

the output raster is supposed to be floating point, perhaps trying to multiply that raster by a constant raster outside you euclidean distance might work

That's an idea! I'll look into it. Thanks!

As Dapper Dan pointed out, the output of EucDistance should be floating point. And, (integer * float) should always give you float. But if you want to make triple sure, you can always convert a grid to float using the Float tool.

One thing that may be messing you up is the artificial ArcGIS designation of a raster as "discrete" or "continuous", which is used for symbology but can be unrelated to the pixel data type.

from arcpy.sa import *
...
OutEucDistance = Float(EucDistance(src_layer, "", resolution, "")) * 0.000621371192

Excellent, that worked very well curtvprice.

Thanks!
