Have any of you considered developing a mobile app to add value to your survey deliverables? I'm thinking particularly in the context of someone who does a lot of boundary surveys. I've played with ArcGIS online app developer, and it seems that it would be pretty easy to add any monuments you survey to a database (with linked photo). A client could then navigate to any corners you set or recover with his smartphone, which is something that people already think they should be able to do.
What do you think? Does this idea have legs?
Since many of us are capturing everything geodetically to begin with, it seems like it would be pretty short work to export points and photos to a geodatabase.
The app would obviously need a splash screen at startup to inform the client that the sole purpose of the app is to find survey markers, that they may not necessarily be in their original positions, should consult a surveyor, etc.
