Save time with ArcGIS and Python

I usually try to avoid using ArcGIS. As I prefer to do geo-spatial analysis in R, using some great packages including sp, raster and rgdal.

But some recent analyses have required some tendonitis inducing* mouse clicking in ArcGIS. Only a simple task of converting rasters to float files. But none the less, thumb, forefinger and mind numbing after a while.

Here is a basic loop which, will convert all rasters in a folder (inFolder) to floats in a output folder (outFolder). You could potentially use this for many different functions in arcpy.

# Import system modules
import arcpy
from arcpy import env

# Set local variables
inFolder = "T:\\Your_Directory\\Environmental Data\\Bioclim_ascii\\Rasters"
outFolder = "T:\\Your_Directory\\Environmental Data\\Bioclim_ascii\\Float"
arcpy.env.workspace = InFolder

for Ras in arcpy.ListRasters():
    arcpy.RasterToFloat_conversion(inFolder + "\\" + Ras, outFolder + "\\" + Ras + ".flt")

* no tendonitis was developed during this demo.
