I want to project many raster files in a folder (but they appear in the content of my ArcGIS project). Here is the screenshot.

These raster files have an unknown coordinate system. When I try to project them manually, the input and output coordinate system is shown below. And I have successfully project several raster files manually.

As you can see, the input and output coordinate system is the same "GCS_WGS_1984". I can manually project these raster files but want to find how to accomplish this using python. Also, after projecting, how to make sure they will appear in my gdb project for future use.

I tried to use the following code but it did not work.

import arcpy

arcpy.env.workspace = r"D:STARinfo_data_test"

#this is the folder where raster files are

arcpy.env.overwriteOutput = True #overwrite the exsiting files



rasterfiles = list(set(arcpy.ListDatasets("b*","Raster")))

#list all the raster files inside the folder with name starting "b"



base = "D:/STAR/assignment/assignment7/Zhenyu_Assign7_GISpro/Zhenyu_Assign7_GISpro.gdb/b90w90r65s400Pro"

#using the exsiting projected raster file as base 

out_coor_system = arcpy.Describe(base).spatialReference

#get the coordinate system of this base raster file



for raster in rasterfiles:

    outraster = raster + "Pro"

    arcpy.ProjectRaster_management(raster,outraster,base)

I do not know how to project these raster files and then put them into my gdb project for future use.

  Why are you projecting to the same geographic coordinate system (i.e. GCS_WGS_84 to GCS_WGS_84)?

  If the coordinate system is unknown you should be using Define Projection, not Project Raster. How do you know it is unknown, have you right-clicked the layer - Properties - Source - Spatial reference?
