Create a Multi polygons feature issue

DominicRobergeIADOT — Sun, 21 Apr 2024 20:50:01 GMT

Hello,

I am trying to create a multi polygons feature into a hosted feature layer and I am stuck! I am creating the array of rings on the fly and trying to replay the array of rings from my geometry template. When I print the information, everything looks good, but when I try to create a the feature, my "array" of rings is really a "string" of rings.

below is the code and the issue I am facing

Any help would be much appreciated

Thanks!

geomList = [] geoArray = [] for d in search_SAhistcountTVMAXFeat: if d.attributes['LandRecordsIDCount']>1: print(d) #Select at records with that specific LandRecordID fExpression = "LandRecordsID='" + d.attributes['LandRecordsID'] +"'" print(fExpression) SLHFLcount = LandHFL.query(where=fExpression ) feat_list = SLHFLcount.features ### NEED TO EXTRACT SINGLE PART FOR EACH POLYGONS strPoly ='' strPoly = '[' print("RAW Geometry ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~") for f in feat_list: print(f.geometry['rings']) print("") strPoly = strPoly+str(f.geometry['rings'])[1:-1]+',' strPoly = strPoly[:-1] strPoly= strPoly+']' print("All Geometry as String~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~") print(strPoly) print("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~") print(" ") #single part template drtest = {'rings': [[[-10478969.9507, 5105644.4034], [-10477947.6054, 5105639.626], [-10477952.3827, 5104555.1757], [-10478998.6146, 5104559.953], [-10479017.7238, 5105333.8779], [-10478979.5053, 5105338.6552], [-10478969.9507, 5105644.4034]]],'spatialReference': {'wkid': 102100,'latestWkid': 3857}} print("Rings from template") print(drtest["rings"]) print(" ") print("after update") drtest["rings"] = strPoly print(drtest["rings"]) print("Creating Template-------------------------") features_to_be_added = [] template_hostedFeature = deepcopy(SLHFLcount.features[0]) template_hostedFeature print("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~") drShape = drtest #geom_union_b print(drShape) new_feature = deepcopy(template_hostedFeature) print("") # assign the updated values new_feature.geometry = drShape #output_geometry[0] new_feature.attributes['LandRecordsID'] = d.attributes['LandRecordsID'] #new_feature.attributes['Property'] = '' print("Final new feature-------------------------") print(new_feature)

Hi @DominicRobergeIADOT

You are converting the geometry to string.

strPoly = strPoly+str(f.geometry['rings'])[1:-1]+','

when you need to keep it as the nested lists and manipulate the lists instead to create your new geometry..

I had been looking at this issue for too long 🙂

got it

geoArray.append(f.geometry['rings'][0])

Thanks!
