  Description:

    Abstract: 

      This Digital Raster Graphic (DRG) was produced by 

      down sampling, georeferencing, and conversion of 

      a 1000 dots-per-inch (dpi) composite image of 

      revised map separates to a standard, USGS GeoTIFF 

      DRG. This DRG includes collar information and 

      is georeferenced to the UTM grid.

    Purpose:

      A DRG is useful as a source or background layer in

      a GIS, as a means to perform quality assurance on

      other digital products, and as a source for the

      collection and revision of  vector data. DRG's can

      also be merged with other digital data, for

      example, DEM's or DOQ's, to provide additional 

      visual information for the extraction and revision of 

      base cartographic information.

    Supplemental_Information:

      The Product ID is 902153.

      The UTM x,y position of pixel 1,1 is

	  605515.04,  4374876.19

Data_Quality_Information:

  Attribute_Accuracy:

    Attribute_Accuracy_Report:

      The DRG is an 8-bit color image. Colors in the DRG reflect

      the visual appearance of the map.  Specific RGB values may

      be used for uniform portrayal of features throughout a

      particular DRG series.  

  Logical_Consistency_Report: Not applicable

  Completeness_Report:

    The DRG is a faithfully reproduced digital image

    of the revised source. Data completeness for DRG

    files reflects content of the digitally revised source.

    Features may have been eliminated or generalized

    during digital revision due to scale and

    legibility constraints. For information on

    collection and inclusion criteria, see Standards for 

    1:24,000-Scale Digital Line Graphs and Quadrangle Maps, 

    Parts 1-4, 6-7, and 9-10, National Mapping Program

  Positional_Accuracy:

    Horizontal_Positional_Accuracy:

      Horizontal_Positional_Accuracy_Report:

	Although the datum of the source is retained, in

	order to be consistent with other USGS digital

	data, this image is cast on the UTM and may

	therefore be INCONSISTENT with the credit note on

	the image collar. DRG's meet the accuracy

	standards of the revised digital source

	only in the area of the DRG that falls within the

	neatline of the image, excluding insets. Overedge

	areas fall outside the transformation boundary

	area (map neatline). As a result, areas outside

	the neatline and beyond the control point extent

	can exhibit anomalies or discrepancies. These

	anomalies will also appear in the map inset area

	and in the map collar.

    Process_Step:

      Process_Description:

	The production procedures, instrumentation,

	hardware, and software used in the collection of

	new version DRG's may vary depending on systems

	used at the contract, cooperator or U.S. Geological

	Survey production site. The process step describes,

	in general, the methods used at a typical USGS 

	production site to produce DRG's derived from high

	resolution, composite raster images of digitally

	revised map separates.

  

	A de-screened, standard color palette, 8-bit, 1000 

	dpi, PackBits compressed Tagged Image File Format 

	(TIFF) raster image of composite map separates is 

	generated during the final stage of digital map revision.



	1. The TIFF is usually re-sampled to create a 500 dpi TIFF

	file.  Pixel resolution is a function of map scale.



	2. The TIFF is georeferenced using coordinates of the map

	graticule ticks.  Each tick is visited and assigned its 

	respective coordinates which are stored in a ground control 

	file.  Geographic transformation software is then 

	used to produce a georeferenced TIFF.



	3. The TIFF image is converted to a GEOTIFF DRG.



	4. Prior to archiving, the DRG undergoes the following

	quality assurance procedures: 



	a. The color index values of each DRG are checked 

	to ensure that the RGB combinations are consistent 

	with the standardized color model 1 palette. 

 

	b. All DRG files are inspected to ensure that they 

	are geometrically consistent with normal map presentation.

  

	c. Each DRG is checked to ensure that data elements 

	in the DRG metadata file correspond to the map collar 

	information and to the information in the associated 

	image file.



	d. Each DRG is checked for georeferencing accuracy

	by comparing  the book value of latitude and

	longitude tick marks with corresponding tick

	intersections in the DRG image.  



	e. GeoTIFF header records in each DRG are checked for 

	completeness and accuracy.



	Current USGS DRG Standards, including product specifications 

	are available via the World Wide Web at:



	http://mapping.usgs.gov/standards  



	DRG Standards and specifications can also be obtained 

	from any of the regional USGS Earth Science Information

    Entity_and_Attribute_Overview:

      Revised DRG Standards, of May 2001, allow up to 256

      non-standard colors. The majority of DRG's in the Sales

      Database were produced according to the original April

      1996 DRG Standards. Each raster entity or pixel, of a

      DRG produced with the old Standards or color model 1 of 

      the new Standards, contains a color index from 0 through

      12.  These indexes reference a color palette of RGB values

      from 0 through 255 in which the standard colors used in 

      the DRG are defined as below:
