I a looking for an iOS app or any approach, that will allow me to do offline map-based surveys and upload the data back to one single database once I am online (like the Esri Collector), but:

  1. in Collector, once I finish one respondent, the second respondent sees the answers, I want to start with blank map.
  2. I will have about 30 people with iPads in the field, I do not want them to see all the answers in one map
  3. I don't have a budget to buy an app

Any ideas?

I can of course take for each respondent a new map, but then I would end up with 700 maps/shapefiles I would have to merge afterwards, what is not user friendly - so I need something like Qfield (QGIS plugin) that would work at iPads.

    For software recommendations there is the Software Recommendations Stack Exchange. – PolyGeo♦ Sep 5 '17 at 21:13
  • You might find GISCloud useful, but perhaps the number of users you require might put this out of reach too: giscloud.com – DPSSpatial_BoycottingGISSE Sep 5 '17 at 21:26
  • Ok, I found the "solution", although it is not superb, it works. I set up layers to be 100% transparent, it means, that users can see layer while creating it, but then it becomes invisible and another user on same iPad wont see previous answers. Works well for me right now. – Jirka Panek Sep 7 '17 at 15:51

  • What are the back-end software requirements that might put the budget of this system out of reach? – DPSSpatial_BoycottingGISSE Sep 5 '17 at 21:25
  • Survey123 does not allow to draw spatial features, it only allows you to answer questions and record your position as point (as far as I know)... – Jirka Panek Sep 5 '17 at 22:01
