Having attachments from Collector be saved in folder on server

ChristopherHolewinski1 — Thu, 22 Dec 2016 19:26:33 GMT

I'm currently attempting to create a map to be used with Collector to aid our assessors in taking pictures of properties. I've created a map that contains the parcel layer and I have attachments enabled, and can successfully attach pictures to each parcel. The problem is that I would like to be able to have those pictures be able to be downloaded/saved to a folder so I can import them into our assessors software? Or does Collector just save those pictures to the cloud with no way to access them outside of AGOL?

Any information would be greatly appreciated.

Thank you,

Chris

If the photos are saved as attachments in AGOL they should be included if you download your data as a file geodatabase. You could then use a python script to export the attachments as image files in a folder. We have variations on this that create folders for each feature and then export the attachments so the resulting files are somewhat organized.

I am using Collector and have a field crew that is attaching photos. Everything works fine except the attach and attach rel tables that are in SDE only allow exporting of 1 photo. I am useing a python script I got from geonet

import arcpy
from arcpy import da
import os

inTable = arcpy.GetParameterAsText(0)
fileLocation = arcpy.GetParameterAsText(1)

with da.SearchCursor(inTable, ['DATA', 'ATT_NAME', 'ATTACHMENTID']) as cursor:
for item in cursor:
attachment = item[0]
filenum = "ATT" + str(item[2]) + "_"
filename = filenum + str(item[1])
open(fileLocation + os.sep + filename, 'wb').write(attachment.tobytes())
del item
del filenum
del filename
del attachment

This is the exact same code we use - maybe check your spacing and indentation to make sure everything is lined up correctly?

If SDE is the issue you might also try to copy/paste everything into a file geodatabase and then run the export script on it.

We use this you will just have to create the local FGDB with a FC and table then follow #7 for modifying the script to fit your use

1) Create local file geodatabase to hold data and attachments you want to download from ArcGIS Online (called data.gdb in script)

2) Create feature class (called myLayer in script), enable attachments, add globalID's

3) Add the following field to the feature class -GlobalID_str, text, length: 50

4) Create table called MatchTable (called MatchTable in script).

5) Add the following fields to the MatchTable table:
- GlobalID_Str, text, length: 50
- PhotoPath, text length: 255

6) Enable "sync" on hosted feature service (http://resources.arcgis.com/en/help/arcgisonline/index.html#//010q000000n0000000)

7) Open AGOL_pullFeatures script in text editor and modify the following:
    -ArcGIS Online username/password
    -REST url to feature service to pull from
    -path to and name of local file geodatabase
    -fields to pull from the hosted feature service (must match local feature class)
    -name of local feature class (this will hold the data from the hosted service and the attachments)
