NE Northeast: Intensity .tif
raster digital data
A one-meter (1m) cell size Intensity 8-bit unsigned integer raster was created from all lidar returns intensity value. The files are delivered in tile format (1000m by 1000m), The rasters are delivered in GeoTIFF (.tif) format and adhere to USGS-NGP Lidar Base Specification, Version 2.1.
This project will support the 3DEP mission, the Federal Emergency Management Agency (FEMA) Risk Mapping, Assessment and Planning (MAP) program and the Natural Resources Conservation Service (NRCS) high resolution elevation enterprise program. The entire AOI covers approximately 8,964 square miles in total in Northeast Nebraska delivered in UTM Zone 14 coordinate system. This project is broken into three delivery blocks. The following block square miles are approximations: Block1 = 4492, Block2 = 2964, Block3 = 1508.
Raster File Type = Tiff
Bit Depth/Pixel Type = 8-bit
Raster Cell Size = 1.0 meter
Intensity Values Normalized To = 8-bit

No restrictions apply to these data.
None. However, users should be aware that temporal changes may have occurred since this dataset was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of its limitations. Acknowledgement of the U.S. Geological Survey would be appreciated for products derived from these data.
Data covers the entire area specified for this project.
The dataset was reviewed to ensure completeness and accuracy.
Using MARS software a one-meter (1m) Intensity GeoTiff (.tif) file was created using all lidar returns intensity value (8bit unsigned integer). The files are delivered in 1000m by 1000m tiles.
