Append Tool - ArcGIS API for Python

CodyPatterson

Hey all,

I'm attempting to work through a project where I take the geometry of a layer, and create a feature using that geometry with a set of attributes that do not match the fields of the destination layer. I attempted to check out the documentation, but it is not helpful for copying features from one layer to another.

How can I copy these features? I do not have access to Arcpy unfortunately or I would have this done already.

I'm open to any ideas!

Thank you in advance!

Hi @CodyPatterson,

I know it's been a while since you posted this and you may have found a solution but I'll post one here as it is something I had to achieve recently myself. It does't use append() but uses the edit_features(adds=[])

This one will take the geometry and match fields from one feature layer to another.

from arcgis.gis import GIS

## Access ArcGIS Online
agol = GIS("home")

## the Item id that contains the source feature layer
source_fs_id = "FS_ITEM_ID"

## the Item id that contains the target feature layer to append to
target_fs_id = "FS_ITEM_ID"

## get the source feature layer as a FeatureLayer object
## you could use a URL and the FeatureLayer object instead
source_fl = agol.content.get(source_fs_id).layers[0]

## get the target feature layer as a FeatureLayer object
## you could use a URL and the FeatureLayer object instead
target_fl = agol.content.get(target_fs_id).layers[0]

## create a match dictionary for each field
field_match = {
    "source_field_1" : "target_field_1",
    "source_field_2" : "target_field_2",
    "source_field_3" : "target_field_3",
    "source_field_n" : "target_field_n"
}

## the list of fields for the feature layer query
out_fields = list(field_match.keys())

## return a feature set of the information
source_fset = source_fl.query(
    out_fields=out_fields
)

## for each feature returned
for f in source_fset.features:
    ## remove the OBJECTID (or FID/OID)
    del f.attributes["OBJECTID"]
    ## replace source field names with target field names
    f.attributes = {new_key: value for new_key, value in zip(field_match.values(), f.attributes.values())}

## add (append) the features
target_fl.edit_features(adds=source_fset)

  

Would love to know if you found a solution yourself or if this helps/works for what you needed?

All the best,

Glen
