A LOCAL 8 WEATHER ALERT is in effect into Wednesday due repeated rainfall. A Flood Watch is in effect for our area until 7 AM Wednesday. Where there are more pauses in the rain, totals will be closer to 2 inches but some will receive at least 4 inches of rainfall total. Creeks and streams run high and areas with poor runoff could face flooding problems. Busy commute hours could face more slowdowns, with fog and standing water on roads as well.
GATLINBURG, Tenn. (AP) -- A group of volunteers is testing the accuracy of a new set of highly detailed three-dimensional maps of the Great Smoky Mountains National Park.
The maps are made using laser pulses transmitted from an airplane and reflected off the ground.
Tom Colson is the park's geographic information systems specialist. He told the Knoxville News Sentinel that the maps are so detailed one can see where a boulder fell down a mountain and came to rest against a stump.
Currently volunteers hiking the backcountry are taking global positioning system readings to confirm the accuracy of the new maps. Once that is done, they will be made available to the public on an interactive website.
Colson expects that to happen around the middle of next year.
