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!
