Description:
Abstract:
These hillshade datasets were derived from USGS 7.5' DEM Quads for the main 8 Hawaiian Islands. Individual DEM quads were first converted to a common datum, and vertical unit, and subsequently mosaicked in ArcGIS 9.x. The hillshade were created from these DEMs using the Hillshade function in ArcGIS 9.2's Spatial Analyst Extension. For all the hillshades, the altitude was set at 45, the Z factor at 1 and the output cell size at 10. The azimuth was set to 45 for the Hawaii (Big Island), Maui and Kauai hillshades. The azimuth was set to 315 for the remaining island hillshades. All rasters are 16 bit signed integers with a spatial resolution of 10 meters. They are in the ERDAS Imagine (.img) format and are referenced to the NAD83 UTM coordinate system. The hillshade for Hawaii (Big Island) is in UTM zone 5N, and the hillshades for the remaining 7 islands are in UTM zone 4N. On this metadata sheet, the bounding coordinates and row and column counts are for a hypothetical 10m grid that would contain the 8 main Hawaiian Islands. For bounding coordinates and the number of rows and columns for each actual, individual hillshade, users should consult their respective layer properties.
Purpose:
These datasets were created to be used in GIS for visualization and analysis.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of these DEMs (and hillshades) depend on the source and resolution of the data samples. DEM data accuracy is derived by comparing linear interpolation elevations in the DEM with corresponding map location elevations and computing the statistical standard deviation or root-mean-square error (RMSE). The RMSE is used to describe the DEM accuracy. For 7.5-minute DEM's derived from a photogrammetric source, 90 percent have a vertical accuracy of 7-meter RMSE or better and 10 percent are in the 8- to 15-meter range. For 7.5- and 15-minute DEM's derived from vector or DLG hypsographic and hydrographic source data, an RMSE of one-half of a contour interval or better is required. The 1-degree DEM data have an absolute accuracy of 130 meters horizontally and 30 meters vertically.
Logical_Consistency_Report:
All users should independently analyze the dataset according to their own needs and standards to determine data usability.
Completeness_Report:
These hillshades cover the full land extent of the main 8 Hawaiian islands (i.e., Hawaii, Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai and Niihau). They were created from 7.5' quad DEMs that were mosaiced together and exported as ESRI grids. Data profiles for this product may not be consistent due to the variable angle between true north and grid north in the UTM coordinate system.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:

Process_Description:
The USGS has used four methods to collect DEM data. Of these methods, only one, interpolation from vectors or digital line graph (DLG) hypsographic and hydrographic data, is currently used for 7.5-minute DEM's and other series DEM's.
