How Do I Avoid Claim Jumping?, Seeking the best techniques for prospecting "open" land Options

[English]

Hi everybody.
HELP!
What's the easiest and most accurate way to view or to plot active mining claims? My goal is to preview claims from a birds-eye-view on a map so that while I'm prospecting I will not trespass on mineral rights. Geocommunicator.com is not accurate, title master platts don't show un-patented claims and LR2000 provides serial numbers that when entered into Geocommunicator.com gives all coordinates (each corner of the claim) in "decimal" format (not degree, minutes and seconds). The area I'm prospecting shows a claim density of 50 - 100 claims and I KNOW there has to be an easier way to identify/view claim bounderies without me:
1) Converting decimal coordinated to degrees, minutes and seconds (for EACH corner of EACH claim).
2) Ploting those coordinates on a topographical map.
In other words...
What's the best technique for prospecting while at the same time avoid trespassing?
THANKS!

Great input everyone!

There are some other instances where I've seen fences and fishing access and or cattle.
State lands, state wildlife areas can have leases for grazing and would have fishing access. But those are not public lands, they are owned by the state and run by state land trust board. Prospecting requires written permission and mining ops of any kind are only under leases and approved plans.

Another situation might be open space, owned by that county or city etc and are not "public" land like NF or BLM. That city or county can make it's own rules to those lands, it's best to ask if you can't find the answer for open space.

Shoot me a pm if you want me to check on some details for you, I may have already done some research in the past for the area your researching.
