Is there a script to perform a spatial join without creating a new feature class, but updates field(s) in the target feature?
spatial join writes a new feature class. Typical workflow for updating fields is using AddJoin then CalculateField tools.
Glad to have found this site. I have been searching endlessly for a py script that will write out the OID + x + y for each feature in a polyline feature class / shapefile but I cannot locate anywhere. I know it would or should be a short script. Can you help?
write out to a text file?
Yes, write out to csv text file
see latest post. cheers

I have just found this site so I’m a newbie. I was wondering if there was a contents page for the different scripts available for download? I seem to be having some trouble finding anything.
Thanks,
Donna
the content is mostly embedded within the posts on this blog. There is not a “download all scripts” page. Though that is an interesting idea.
We’ve been trying to get the https://arcpy.wordpress.com/tag/football/ script to work, but have not been successful to get the output files to fill. They output files create but are empty. Can someone help us???!!!!
Here is our script:
#Function 1
arcpy.CreateFileGDB_management(“C:\\Users\\carmodyco\\Desktop\\Python\\Carmody_Final”, “final.gdb”)
def build_football_field(final,footballfield): # function called build_football_field (output_gdb, output_feature_class):
print(‘Creating football field.’)
football_field_fields = (‘Polygon’, ‘Packers’) # creating the object (‘SHAPE@’, ‘TEAM’)
fc =os.path.join(“final.gdb”,”footballfield”) # fc = joining the paths of final.gdb and footballfield (output gdb, outputfeatureclass)
if not arcpy.Exists(os.path.join(“final.gdb”, “footballfield”)): #checking to see if path exists
arcpy.CreateFeatureclass_management(“final.gdb”, “footballfield”, “POLYGON”, “#”,”DISABLED”,”DISABLED”, arcpy.SpatialReference(3857)) #creates a polygon feature class in final.gdb with spatial reference of WGS 1984 Web Mercator
arcpy.AddField_management(fc, football_field_fields[1], “TEXT”,field_length=20) #adds a new field to the table
cursor = arcpy.da.InsertCursor(fc, football_field_fields) #inserting a row into the table (in_table, field_names)
field = [(0, 533.3), #vertices of the field
(1000, 533.3),
(1000, 0),
(0, 0)]
cursor.insertRow([field,””]) #inserting row
home_endzone = [(-100, 533.3), #vertices of the home endzone
(0, 533.3),
(0, 0),
(-100, 0)]
cursor.insertRow([home_endzone, “Packers”]) #inserting row for home_endzone called Packers
away_endzone = [(1000, 533.3), #vertices of away_endzone
(1100, 533.3),
(1100, 0),
(1000, 0)]
cursor.insertRow([away_endzone, “Bears”]) #inserting row for away_endzone called Bears
#need to call the function
field1 = build_football_field(“C:\\Users\\carmodyco\\Desktop\\Python\\Carmody_Final\\final.gdb”, “C:\\Users\\carmodyco\\Desktop\\Python\\Carmody_Final\\final.gdb\\footballfield”)
#Function 2:
def build_yard_lines(final,yardlines): #function called build_yard_lines (output_gdb, output_feature_class):
print(‘Creating yard markers.’)
football_line_fields = (‘POLYLINE’, ‘MARKER’) # creating an object (shape@, marker)
fc = os.path.join(“final.gdb”, “yardlines”) # joining paths of yardlines and final.gdb(ouput_gdb, output_feature_class)
if not arcpy.Exists(os.path.join(“final.gdb”, “yardlines”)): #checking to see if path exists
arcpy.CreateFeatureclass_management(“final.gdb”, “yardlines”, “POLYLINE”, “#”, “DISABLED”,”DISABLED”, arcpy.SpatialReference(3857))
#creates a polyline feature class in final.gdb with spatial reference of WGS 1984 Web Mercator
arcpy.AddField_management(fc, football_line_fields[1], “TEXT”,field_length=10) #adding new field to the table
cursor = arcpy.da.InsertCursor(fc, football_line_fields) #inserting a row into the table (in_table, field_names)
markers = [10, 20, 30, 40, 50, 60, 70, 80, 90] #creating markers
for marker in markers:
line_1 = [(marker * 10, 533.3 / 2), (marker * 10, 0)]
line_2 = [(marker * 10, 533.3 / 2), (marker * 10, 533.3)]
if marker > 50:
cursor.insertRow([line_1, str(100 – marker)])
cursor.insertRow([line_2, str(100 – marker)])
else:
cursor.insertRow([line_1, str(marker)])
cursor.insertRow([line_2, str(marker)])
lines = build_yard_lines(“C:\\Users\\carmodyco\\Desktop\\Python\\Carmody_Final\\final.gdb”,”C:\\Users\\carmodyco\\Desktop\\Python\\Carmody_Final\\final.gdb\\yardlines”)
I noticed a few errors in your code that could cause the error. I’ve refactored what you posted and shared the code at https://github.com/gbrunner/nfl-drive-charts-in-arcgis/blob/master/response_to_wordpress.py. Also, take a look at https://github.com/gbrunner/nfl-drive-charts-in-arcgis/blob/master/create_drive_chart.py too. That is the tool I used to create drive charts.
