Tree survey question

What’s the best way to use Google Earth to do a field survey and record points for landmark trees? This doesn’t need to be design quality information, just enough to let family members and partners visualize how a division of land might work.

How to build a GPS compass

I'm looking to build or to buy a GPS compass that can be paired to another compass without the need of other devices such as a smartphone but I'd like it to have moving parts, resembling a normal compass.

GPS carriers for M2M or SCADA

Could GPS carriers like L1, L2 or L5 be used for M2M or SCADA leaving out the service of GPS ? If so, is it legal?
