For what I experienced, first, parcels must be in wkid:3857 without curves in the geometry. Also, there should not have identicals parcels overlapping and multiparts are suggested to be desagregated in single parts.

@jcarlson yes using a very small float preserve the precision. I think it's the best solution because I rather not write to an intermediate format. Thanks for your help!

@David_Brooks The arcpy.conversion.FeaturesToJSON throws a 999999 Error when used on layer that has curves.

@David_Brooks yes that could be a solution, but converting from geodatabase to shapefile brings a lot of side effects that I am trying to get around.

That could be a problem because the topology and the precision is important. There must be another way. For instance when you output a geojson, the curves are replaced by vertices because curves are not in the spec of geojson.

Hi, thanks for the reply! Will this generalize the whole geometry or just replace the curve with vertices?

Hi, Is there a way to replace curve rings in polygon geometries with vertices along the curve using arcpy? I need to output a specific json of a featureSet but curveRings are not allowed. Is there a mathematical function that can be used? Thank you for the info! Maxime Demers

Further readings make me realize that I must use a OAuth2.0 authentification method.

Hi, I am trying to use the Urban API with Python but I got an authentification error: GraphQL query failed with 1 errors [{'message': 'The access token provided is invalid or expired.', 'extensions': {'code': 'UNAUTHENTICATED'}}] Im not sure why the token I provided to the urban api url is not working because it was generated using arcpy like below: import arcpy
from sgqlc.operation import Operation
from sgqlc.endpoint.http import HTTPEndpoint
from urban_api_schema import urban_api_schema as schema
arcpy.SignInToPortal("https://www.arcgis.com", "myUserName", "MyPasswOrd")
#token is generated correctly
token = arcpy.GetSigninToken()
urban_api_url = "https://urban-api.arcgis.com/graphql" + '?token=' + token['token']
endpoint = HTTPEndpoint(urban_api_url)
#here it's the function that call the api to update the parcels
for parcel_chunk in parcels_chunks:
op = Operation(schema.Mutation)
create_parcels = op.create_parcels(urban_database_id="1c80e3e815594fd288d347e132138f0a", parcels=parcel_chunk)
create_parcels.attributes.__fields__('global_id')
json_data = endpoint(op)
errors = json_data.get('errors')
if errors:
print(errors) Any helps would be greatly appreciated! Thanks, Maxime Demers

Hi, I would like to know if there is a way to prevent Collector to be able to add or remove attachment for a perticular web map? We need attachments on a layer, but in that Collector application, we dont want users to be able to modify attachments, but to modify some attributes only. We dont need to see attachments at all in that Collector application if that helps. Thank you!

Hi, I would like to run standalone python 3 scripts (using arcpy) in scheduled tasks on arcgis server v10.6.1 on Windows Server 2019. I have found an installation of python 3 in this location: C:\Program Files\ArcGIS\Server\framework\runtime\ArcGIS\bin\Python\ and I wonder if it's ok to use it for running standalone scripts because ArcGIS Pro is not installed on that server, there is only ArcGIS Server. Also, I have read that I have to create a new python env in order to keep the arcgispro-py3 intact. Is it ok to create a new python env in the C:\Program Files\ArcGIS\Server\framework\runtime\ArcGIS\bin\Python\envs ? Do you have any suggestions in regard with what I am trying to do? Many thanks, Maxime
