Copy feature classes from feature datasets (2024)

byDilsonKitoko

Hello, I'm trying to write a code to copy the feature classes inside of feature datasets.

I'm having two issues. I have 2 feature datasets, but when I do the "print(fcList)" , seems like only the features one dataset are being listed. The second one is that the tool stucks at the arcpy.CopyFeaturesHere below my code:

Thanks in advance for any tip.

import arcpyfrom arcpy import envenv.workspace = r'C:/Trials/NPD_FactMapsData_v3_0_2.gdb'# Set local variablesOutputFGDB = r'C:/Trials/New File Geodatabase.gdb'#env.workspace = arcpy.GetParameterAsText(0)datasetList = arcpy.ListDatasets('*','Feature')try: for dataset in datasetList: env.workspace = dataset fcList = arcpy.ListFeatureClasses() print (fcList) for fc in fcList: print('copying...') arcpy.CopyFeatures_management(fc,OutputFGDB) print("copy finished")except: # Report if there was an error arcpy.AddError("Could not copy feature classes") print ("Could not copy feature classes") #print arcpy.GetMessages()‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

for dataset in datasetList:

add an indentation after this for the block, get rid of the try except block as this is likely failing with the lack of indent then excepting, add lots or print statements and review

Hello, thanks for your reply. I "cleaned" the code, but still not working. Still starts failing atfcList. Only the features from one dataset are being listed.For the second dataset fcList is returning "None". If I printdataset or datasetList, i can see the 2 datasetslisted. Then in thearcpy.CopyFeatures its try to write a file with shapefile extension, of course an error.

import arcpyarcpy.env.workspace = r"C:\Trials\NPD_FactMapsData_v3_0_2.gdb"OutputFGDB = r"C:\Trials\New File Geodatabase.gdb"datasetList = arcpy.ListDatasets() for dataset in datasetList: arcpy.env.workspace = dataset fcList = arcpy.ListFeatureClasses() for fc in fcList: arcpy.CopyFeatures_management(fc, OutputFGDB)‍‍‍‍‍‍‍‍‍‍‍

I think in CopyFeatures you would specify the path for the output FC rather than the destination GDB/Folder, grab the fc name and use that within your loop (something like os.path.join(OutputFGDB, fc_name). Have a look at the feature class class attributes and see the name property, may well be fc_name = fc.name, also ensure you import os module.

for fc in fcList: also has no indent on what you've copied.

Again put in some print statements and it would be helpful to see what output, messages you get also.

To get the script to iterate through your datasets you need to specify what datasets to use.

import arcpyfrom arcpy import envimport osenv.workspace = "C:\\GDB.gdb"outGDB = "C:\\outGDB.gdb"env.overwriteOutput = TruedataSetList = arcpy.ListDatasets(feature_type='feature')#check to make sure the list is populatingprint dataSetListfor ds in dataSetList: for fc in arcpy.ListFeatureClasses(feature_dataset=ds): #Check to see if the list is populating. print fc arcpy.CopyFeatures_management(fc, outGDB)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Another good options is to use Walk and allow it to collect the feature classes within your datasets.

Hello Mark,

Thank you, after your tips i figure it out the isse with listing all fcs. For the ouput I had to os.path.basename and splitext to get the fc names and thenos.path.join to generate the full output.

Cheers,
