With LIDAR's capabilities to easily collect highly accurate above-ground and ground elevation data, agencies are finding this detailed data allows them to make better decisions as they devise programs to man- age, restore and plan natural resources to effectively conserve land resources for agricultural purposes. In natural-resource conservation, LIDAR can be used L in a variety of ways, including watershed and conser- vation planning, engineering, soil surveys, hydrology modeling and habitat restoration. With this last item, LIDAR has played a significant role. The Rainwater Basin and LIDAR The Rainwater Basin is a 6,100-square-mile landscape that was formed at the end of the last ice age, when glacial 24 G E O W O R L D / A P R I L 2 O 1 0 ight Detection and Ranging (LIDAR) continues to prove its worth in multiple arenas, including natu- ral resources as well as agricultural management BY SHANDY BITTLE AND DOUG JACOBY Space-Based Prospecting Remote Sensing Helps Find Gold Deposits Enables Natural-Resource and Agricultural Management 16 G E O W O R L D / J U N E 2 O 1 0 winds carved thousands of shallow, bowl-shaped depres- sions that are now fed by rainwater and melting snow. This area of shallow lakes, marshes and wetlands is located in south-central Nebraska and north-central Kansas. An area in the narrowest portion of the migration route is known as the Central Flyway, a path that spans a mere 150 miles where many millions of waterfowl rest, feed and pair on their annual migrations. These migratory birds include 3 to 6 million snow geese, 4 million mallards, 900,000 white-fronted geese, 900,000 pintails, and millions of other migrating birds, including Canada geese, shorebirds and cranes. Throughout much of the 20th century, wetlands were drained for farming, bisected by roads or silted-in by erosion, until only about 10 percent of the original Rainwater Basin wetlands remain. Compounding the issue is the fact that the bowl-shaped depressions that have been drained or impacted are only fed Data Acquisition Satellite Imaging RAINWATER BASIN JOINT VENTURE
