<h2>A table of what each digit in a decimal degree signifies:</h2> <ul> <li>The sign tells us whether we are north or south, east or west on the globe.</li> <li>A nonzero hundreds digit tells us we&#39;re using longitude, not latitude!</li> <li>The tens digit gives a position to about 1,000 kilometers. It gives us useful information about what continent or ocean we are on.</li> <li>The units digit (one decimal degree) gives a position up to 111 kilometers (60 nautical miles, about 69 miles). It can tell us roughly what large state or country we are in.</li> <li>The first decimal place is worth up to 11.1 km: it can distinguish the position of one large city from a neighboring large city.</li> <li>The second decimal place is worth up to 1.1 km: it can separate one village from the next.</li> <li>The third decimal place is worth up to 110 m: it can identify a large agricultural field or institutional campus.</li> <li>The fourth decimal place is worth up to 11 m: it can identify a parcel of land. It is comparable to the typical accuracy of an uncorrected GPS unit with no interference.</li> <li>The fifth decimal place is worth up to 1.1 m: it distinguish trees from each other. Accuracy to this level with commercial GPS units can only be achieved with differential correction.</li> </ul>
