Hi:

I think that using the Arduino to help with geologic mapping is "the long way around".
Nowdays, most smartphones have built-in GPS and compasses and there are probably lots of cheap or free apps that would help you with mapping. The typical cost of a smartphone with GPS and compass is $50 to $100 new, cheaper on the used market.

A good example of archaeological mapping may be found at:
Landscape Surveying using Handheld GPS Receivers

The app "Geology Sample Collector" may be something you can use.

Or maybe GeDroid Mapper:

I stumbled across this GIS tablet software recently: https://github.com/NathanW2/Roam/tree/linux
I haven't had a go at compiling it on a RPi yet. They are looking to eventually get it to compile for the Android platform. It runs via Python and Qt and looks to be very advanced.

The HDMIPi screens (non-touch screen) are being shipped soon and hopefully after that, the RPi display (built in touch screen). Adafruit do sell a range of small resistive and capacitance touch screens.

I was going to try and writing something simple my self, perhaps using pygame, but if Roam would run on a RPi, I would rather help develop that, as it hooks right into the QGIS desktop software.

My needs are for a Biology GIS data recorder and waypoint locator. I want to be able to record data about a plant and then find it again the following year. I use QGIS back at home to make up the species maps.

In case anyone finds this and is interested in building their own GIS Tablet, I have started a post here: http://www.raspberrypi.org/forums/viewt ... 83#p676683

about my attempt at building one.
