Other_Citation_Details:

The U. S. Geological Survey, in cooperation with the National Park Service (NPS) and the National Aeronautics and Space Administration (NASA), is to provide the coastal management community with usable, useful digital elevation products. The U. S. Geological Survey processes aircraft Lidar data (provided by NASA), develops software tools and algorithms to use and analyze the data and make products available to the coastal management community through a variety of media, including the internet, CD-ROMs, DVDs and data reports.

Abstract:

GIS contour lines of Sagamore Hill National Historic Site derived from a Lidar GeoTIFF file.

Purpose:

This contour shapefile was generated from a Lidar GeoTIFF. It shows contour lines at 1 meter intervals, and will be used to aid in the interpretation and display of Lidar data files.

Supplemental_Information:

See the source Lidar GeoTIFF tile for more specific accuracy information.

Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcMap 9.2.0

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The expected accuracy of the measured variables are as follows: attitude within 0.07 degree, 3cm nominal ranging accuracy, and verticle elevation accuracy of +/- 15cm (bare earth). Quality checks are built into the data-processing software.

Logical_Consistency_Report: This layer was generated from an existing Lidar tile.

Completeness_Report:

Contour lines break where there was no data (value of -100) in the original Lidar tiles.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Raw elevation measurements have been determined to be within 1.5 meter horizontal accuracy. Processing steps (grid interpolation) may introduce additional error which has not been tested at the time of this publication.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Elevations of the DEM are vertically consistent with the point elevation data, +/- 15cm.

Process_Description:

The Lidar GeoTIFF data was too coarse to create aesthetically pleasing contours. A Neighborhood Statistics operation was run on the Lidar GeoTIFF file in ArcMap. The settings for the Neighborhood Statistics operation were a 14x14 cell rectangle, using the mean as the statistic type and then output to a temporary raster grid.

Process_Step:

Process_Description:

Contour lines were generated using the Contour operation in ArcMap. The temporary Neighborhood Statistics grid was used as the input surface and the contour interval was set to 1 (meter). This was output to a permanent shapefile.
