Using clip tool (ArcGIS) for iteration/looping 2 GDBs in : one for clipped data, second - for clipping features

Question

I have 2 GDBs. The first one (let's name it X.gdb) contains feature classes (A,B,C...n) that are to be clipped. The second gdb (Y.gdb) contains fc (let's name it border1, border2, border3...) with only one polygonal feature (municipal district) in each. These are clipping features. What I need to do is to create model/python script, that creates separate gdb for every clipping feature (border1.gdb, border2.gdb, border3.gdb...) with clipped features from X.gdb

What kind of mistake did I make?

Answer 1

Merge your municipal polygon features into a single file. Make sure there is a name field in your merged out put to specify the polygon representing it's respective municipal district. This code should do the trick once you replace the proper parameters and file locations:

import arcpy
import os

outputFolder = r"D:/test"
arcpy.env.workspace = r"D:/test/data_3857.gdb"
arcpy.env.overwriteOutput = True

#create clip tool parameters
ClipFeatures = r"D:/test/Y.gdb/borders"
fcs = arcpy.ListFeatureClasses()

# use a search cursor to cycle through each municipal district in your merged file, make sure there is a field representing municipal district name, I'm using "Municipality_name" here
with arcpy.da.SearchCursor(ClipFeatures, ["SHAPE@", "NAME"]) as rows:
    for row in rows:
        # create fgdb in outputFolder variable, this will create a folder with   the Municipal district name and a file gdb named muni_features.gdb to store the clipped features 
        outGDB = os.path.join("MD_" + row[1], "Muni_features.gdb")
        arcpy.CreateFileGDB_management(outputFolder,outGDB)
        print "created", outGDB
        geom = row[0]
        #now clip out each feature in
        for fc in fcs:
            out_feature_class=os.path.join(outputFolder, outGDB,"MD_" + row[1] +  os.path.basename(fc))
            print out_feature_class
            arcpy.Clip_analysis(fc,geom,out_feature_class)
        del row

Your indentaion is still off. Copy this code. Paste it into a text file. Name it MyClip.py. In the python window in ArcMap, right click in the interactive window. Choose load. Upload MyClip.py. Press enter. Let the code run.

import arcpy
import os

outputFolder = r"D:/test"
arcpy.env.workspace = r"D:/test/data_3857.gdb"
arcpy.env.overwriteOutput = True

#create clip tool parameters
ClipFeatures = r"D:/test/Y.gdb/borders"
fcs = arcpy.ListFeatureClasses()

# use a search cursor to cycle through each municipal district in your merged file, make sure there is a field representing municipal district name, I'm using "Municipality_name" here
with da.SearchCursor(ClipFeatures, ["SHAPE@", "NAME"]) as rows:
    for row in rows:
        # create fgdb in outputFolder variable, this will create a folder with   the Municipal district name and a file gdb named muni_features.gdb to store the clipped features 
        outGDB = os.path.join(outputFolder, row[1], "Muni_features.gdb")
        print "created ", outGDB
        geom = row[0]
        #now clip out each feature in
        for fc in fcs:
            out_feature_class=os.path.join(outGDB,row[1] +  os.path.basename(fc))
            arcpy.Clip_analysis(fc,geom,out_feature_class)
            del fc
        del row
