Hello,
I would like to raise discussion about Android surveying software I'm involved in. It is open source and you can get it from https://play.google.com/store/apps/details?id=com.astoev.cave.survey.
I know many cavers are happy working with DistoX and I have to admit this is a great way of surveying. CaveSurvey tries to help if you don't have one or you already have different surveying devices. So far it can use any combination of manual input, several(5 so far including DistoX) Bluetooth laser distance meters or the Android sensors. There is also simple preview, sketching and several export options, etc but is a nice ground for extending it further. Slightly outdated poster of the features is present here https://raw.githubusercontent.com/lz1asl/CaveSurvey/master/doc/CaveSurveyPoster.png.
What do you think?
Best,
Aleksandar
