Smartphones have incorporated many sensors and some of them can be helpful for a geologist in the field:
- They have GPS, so it is possible to register your route in a Google Maps map. I find this may be interesting in combination with image, video, audio or text registration.
- They have an orientation sensor, so it is possible to create a compass with a few lines of code. The doubt is whether someone is going to trust this kind of device instead of an expensive mechanical compass.
- Some devices measure color. I doubt this can be very useful (color "x4832789bjkfbjk" or whatever is the output).
I am curious to maybe develop one in the future, or encourage a reader to program one.
How can the device help geologists in the field?
