LIDAR IN NEBRASKA

Nebraska has been relying on elevation data from as distant as 75 years. A statewide effort is underway to replace this outdated product for modern applications. The Nebraska GIS Council, responsible for promoting efficient use of GIS technology and coordinating public investment in spatial data across the state, is coordinating this effort. To this end, it has formed various workgroups relating to what it calls the Nebraska Spatial Data Infrastructure (NESDI). Three of the NESDI datasets are foundational to all others: geodetic control, elevation, and orthophotography. This poster focuses on elevation, introduces LiDAR technology, illustrates collection progress, and demonstrates that LiDAR, in conjunction with geodetic control and orthophotography, is a robust and cost-effective approach to building a solid foundation for all other datasets.
