			<abstract>The dataset lies within Flathead and Lake Counties in northwestern Montana.
The bare earth digital elevation models (DEM) represent the earth's surface with all vegetation and human-made structures removed.  The bare earth DEMs were derived from LiDAR data using TIN processing of the ground point returns.  The DEM grid cell size is 3 feet.  The elevation units are in feet.  Some elevation values have been interpolated across areas in the ground model where there is no elevation data (e.g. over water, over dense vegetation).

Watershed Sciences, Inc. collected the LiDAR and created this data set for the Montana Department of Natural Resources and Conservation</abstract>

		<useconst>In some areas of heavy vegetation or forest cover, there may be relatively few ground points in the LiDAR data.  TINing the points produces large triangles and hence the elevations may be less accurate within such areas.

Elevation values for open water surfaces are not valid elevation values because few LiDAR points are returned from water surfaces.  Triangles were created across water surfaces by interpolating from the nearest land points.</useconst>

		<logic>LiDAR flight lines have been examined to ensure that there was at least 50% sidelap, there are no gaps between flightlines, and overlapping flightlines have consistent elevation values.

Shaded relief images have been visually inspected for data errors such as pits, border artifacts, gaps, and shifting.  The data was examined at a 1:2000 scale.</logic>

				<procdesc>Acquisition.

The LiDAR data was collected from September 22nd - 29th, 2009.   The survey used a Leica ALS50 Phase II laser system mounted in a Cessna Caravan 208.  Near nadir scan angles were used to increase penetration of vegetation to ground surfaces.   Ground level GPS and aircraft IMU were collected during the flight.</procdesc>

				<procdesc>Processing.

1. Flight lines and data were reviewed to ensure complete coverage of the study area and positional accuracy of the laser points.
2. Laser point return coordinates were computed using ALS Post Processor software, IPAS Pro GPS/INS software, and Waypoint GPS, based on independent data from the LiDAR system, IMU, and aircraft.
3. The raw LiDAR file was assembled into flight lines per return with each point having an associated x, y, and z coordinate.
4. Visual inspection of swath to swath laser point consistencies within the study area were used to perform manual refinements of system alignment.
5. Custom algorithms were designed to evaluate points between adjacent flight lines.  Automated system alignment was computed based upon randomly selected swath to swath accuracy measurements that consider elevation, slope, and intensities.  Specifically, refinement in the combination of system pitch, roll and yaw offset parameters optimize internal consistency.
6. Noise (e.g., pits and birds) was filtered using ALS postprocessing software,  based on known elevation ranges and included the removal of any cycle slips.
7. Using TerraScan and Microstation, ground classifications utilized custom settings appropriate to the study area.
8. The corrected and filtered return points were compared to the RTK ground survey points collected to verify the vertical and horizontal accuracies.
9.  Points were output as laser points, TINed and GRIDed surfaces.</procdesc>
