I have two different folder (workspace1 and workspace2) with Rasters data with the two different parameters. Whatever raster in workspace1 (input raster name e.g 001_mean, 002_mean, 003_mean, 004_mean ….012_mean ), I would like to execute below equation

((Raster – Min Rater value) * (0.95 – 0.01)) / (Max raster value – Min Raster Value )

and save it into outputfolder 1 name of output (e.g. 001_FPAR, 002_FPAR, 003_FPAR, 004_FPAR ….012_FPAR)

After calculating workspace1, I want to take different raster file from workspace 2 (raster name , 001_SR, 002_SR, 003_SR, 004_SR……012_SR) and multiply it with each raster file with calculated raster from workspace 1 and save it into outputfolder 2 as name of 001_APAR, 002_APAR, 003_APAR, 004_APAR ……012_APAR.

I have written the code below but its giving error.

import arcpy  
from arcpy.sa import *  

workspace1 = glob.glob(r"D:\MODIS-NDVI-2012\MASKED-NDVI-2012A") 
workspace2 = glob.glob(r"D:\MODIS-NDVI-2012\MASKED")
outFolder1 =  r"D:\MODIS-NDVI-2012\FPAR"
outFolder2 =  r"D:\MODIS-NDVI-2012\APAR"

list = arcpy.ListRasters() 

for inRaster in list:
    localRaster = Raster(inRaster) 
for r in workspace1 
NDVIMINResult = arcpy.GetRasterProperties_management(inRaster1, "MINIMUM")  
NDVIMAXResult = arcpy.GetRasterProperties_management(inRaster1, "MAXIMUM")  

NDVIMin = float(NDVIMINResult.getOutput(0))  
NDVIMax = float(NDVIMAXResult.getOutput(0))
outminus = Minus(inRaster1, NDVIMin)
outminus1 = Minus(0.95-0.01)
outmultiply = Multiply(outminus,outminus1)
outminus2 = Minus(NDVIMax, NDVIMin)
outdevide = Devide(outmultiply,outminus2)
outdevide.save = (outdevide) 
for r in workspace2
outmultiply1 = Multiply (outdevide,Raster)
outmultiply1.save (outmultiply1)

Could you please copy the error message you received and paste it here? I cant be sure without seeing the error message but I think that you have a problem with the following line

outminus1 = Minus(0.95-0.01)

Here you used one parameter with the function "Minus" instead of two.


Here are the corrected lines:

for r in workspace1:
    NDVIMINResult = arcpy.GetRasterProperties_management(inRaster1, "MINIMUM")  
    NDVIMAXResult = arcpy.GetRasterProperties_management(inRaster1, "MAXIMUM")

You should pay attention to the indentation of the block of code that follows the for statement.

  • the error massage is Parsing error SyntaxError: invalid syntax (line 14) Aug 17, 2016 at 15:07
  • You need to add ":" after the for statement in line 14 and indent the following block of code to the right Aug 17, 2016 at 15:15
  • Would you please copy and paste the corrected line . Aug 17, 2016 at 15:17
  • I will add it in a separate answer Aug 17, 2016 at 15:19
  • @MohannadAdham please don't add as a separate answer - you can edit this one and add to it.
