We collect scientific data at remote sites and just started using Collector to take multiple photos for each site. It's nice that we can use our field device to see the photos when we go back for re-visits, but we need to be able to bulk download all of the photos we collect for each site, with unique site IDs, to save and use them on our computers. Currently, the only option available to us is to save photos one by one to our device (iPad) photos app, then move them to the computer via USB connection. It would be ideal if ESRI could provide functionality with ArcGIS Online hosted feature services to export photo attachments.
Hi Erin,
I have a script that will do this. I export the fgdb to arcmap, then perform a join and rename the attachments from the joined table, then export the attachments using the script. It is definitely easier than one by one, and keeps the naming convention you choose. For multiple photos at same site, it names them the same but adds a sequential number at the end. Let me know if you want more info, as this is kind of an old post, you likely have a solution already.
Can you post more information on how I can access your script to bulk export of photos from Collector AGOL?
I was just working with support and was provided the attached python script for bulk download of attachments.
1. Download the hosted service to a FGDB
2. Open FGDB in ArcMap
3. Create a toolbox item
4. Copy script into the toolbox
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

TiffanyTuro, I'd be very interested in your script for renaming the attachments!
