This layer includes the BGS 1:250k published maps. Maps in this series show three sorts of geological information; solid ‘bedrock’ geology, (S), Quaternary or ‘drift’ geology (Q), or sea-bed sediments (Ss). These are usually presented as separate sheets, although sea-bed sediments and Quaternary geology, or sea-bed sediments and solid geology may be shown on the same sheet. Quaternary geology maps are for offshore areas only. Sheets were published between 1977 and 2000 with a few special area sheets up to 2009. Sheets were issued on a regular grid based on the UTM of two degrees longitude by one degree latitude. Note the publication dates (latest mapping is available through the BGS digital maps).

Historical maps contain a wealth of information not generally available, but they must be referenced to well-known coordinate systems for maximum use in spatial analysis. Existing georeferencing tools are essentially manual, requiring considerable data entry, much panning and zooming, and precise on-screen digitizing. Here we present alternative approaches based on pattern-matching and spatial computing intended to overcome the inefficiencies of standard tools. We also describe and make available two computer programs implementing the methods discussed. The first, designed for large-scale quadrangles, locates map boundaries, finds ground control points, and produces georeferenced images without operator assistance. Experiments show that quadrangle georeferencing can be reliably automated (88% success rate in our tests). A second program, developed for general maps at any scale, uses self-learning and other approaches to overcome most of the manual aspects of georeferencing. Both programs find control points with single-pixel accuracy, yield transform errors on the order of map linewidth, and can produce warped or unwarped images as desired.

The National Aeronautics and Space Administration (NASA) Aircraft Scanners data set contains digital imagery acquired from several multispectral scanners, including Daedalus thematic mapper simulator scanners and the thermal infrared multispectral scanner. Data are collected from selected areas over the conterminous United States, Alaska, and Hawaii by NASA ER-2 and NASA C-130B aircraft, operating from the NASA Ames Research Center in Moffett Field, California, and by NASA Learjet aircraft, operating from Stennis Space Center in Bay St. Louis, Mississippi. Limited international acquisitions also are available.
In cooperation with the Jet Propulsion Laboratory and Daedalus
Enterprises,Inc., NASA developed several multispectral sensors. The
data acquired from these sensors supports NASA's Airborne Science and
Applications Program and have been identified as precursors to the
instruments scheduled to fly on Earth Observing System platforms.
THEMATIC MAPPER SIMULATOR
The Thematic Mapper Simulator (TMS) sensor is a line scanning device
designed for a variety of Earth science applications. Flown aboard
NASA ER-2 aircraft, the TMS sensor has a nominal Instantaneous Field of
View of 1.25 milliradians with a ground resolution of 81 feet (25 meters)
at 65,000 feet. The TMS sensor scans at a rate of 12.5 scans per second
with 716 pixels per scan line. Swath width is 8.3 nautical miles
(15.4 kilometers) at 65,000 feet while the scanner's Field of View is
42.5 degrees.
NS-001 MULTISPECTRAL SCANNER
The NS-001multispectral scanner is a line scanning device designed to
simulate Landsat thematic mapper (TM) sensor performance, including a
near infrared/short-wave infrared band used in applications similar to those
of the TM sensor (e.g., Earth resources mapping, vegetation/land cover
mapping, geologic studies). Flown aboard NASA C-130B aircraft, the NS-001
sensor has a nominal Instantaneous Field of View of 2.5 milliradians with a
ground resolution of 25 feet (7.6 meters) at 10,000 feet. The sensor has a
variable scan rate (10 to 100 scans per second) with 699 pixels per scan line,
but the available motor drive supply restricts the maximum stable scan speed
to approximately 85 revolutions per second. A scan rate of 100 revolutions per
second is possible, but not probable, for short scan lines; therefore, a
combination of factors, including aircraft flight requirements and maximum
scan speed, prevent scanner operation below 1,500 feet. Swath width is 3.9
nautical miles (7.26 kilometers) at 10,000 feet, and the total scan angle or
field of regard for the sensor is 100 degrees, plus or minus 15 degrees for
roll compensation.
THERMAL INFRARED MULTISPECTRAL SCANNER
The Thermal Infrared Multispectral Scanner (TIMS) sensor is a line scanning
device originally designed for geologic applications. Flown aboard NASA
C-130B, NASA ER-2, and NASA Learjet aircraft, the TIMS sensor has a
nominal Instantaneous Field of View of 2.5 milliradians with a ground
resolution of 25 feet (7.6 meters) at 10,000 feet. The sensor has a
selectable scan rate (7.3, 8.7, 12, or 25 scans per second) with 698 pixels
per scan line. Swath width is 2.6 nautical miles (4.8 kilometers) at
10,000 feet while the scanner's Field of View is 76.56 degrees.

A digital raster graphic (DRG) is a scanned image of an U.S. Geological Survey (USGS) standard series topographic map, including all map collar information. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Universal Transverse Mercator projection. The horizontal positional accuracy and datum of the DRG matches the accuracy and datum of the source map. The map is scanned at a minimum resolution of 250 dots per inch. DRG's are created by scanning published paper maps on high-resolution scanners. The raster image is georeferenced and fit to the UTM projection. Colors are standardized to remove scanner limitations and artifacts. The average data set size is about 6 megabytes in Tagged Image File Format (TIFF) with PackBits compression. DRG's can be easily combined with other digital cartographic products such as digital elevation models (DEM) and digital orthophoto quadrangles (DOQ). DRG's are stored as rectified TIFF files in geoTIFF format. GeoTIFF is a relatively new TIFF image storage format that incorporates georeferencing information in the header. This allows software, such as ArcView, ARC/INFO, or EPPL7 to reference the image without an additional header or world file. Within the Minnesota Department of Natural Resources Core GIS data set the DRG's have been processed to be in compliance with departmental data standards (UTM Extended Zone 15, NAD83 datum) and the map collar information has been removed to facilitate the display of the DRG's in a seamless fashion. These DRG's were clipped and transformed to UTM Zone 15 using EPPL7 Raster GIS.
DRGs are a useful backdrop for mapping a variety of features. Colors representing various items in the image (contours, urban areas, vegetation, etc.) can be turned off or highlighted depending on the mapping application. In ArcView this is done by choosing the "Colormap" option when editing the DRG theme's legend. A variety of other ArcView tools exist to make working with DRGs easier.
Also included:
Metadata for the scanned USGS 24k Topograpic Map Series (also known as 24k Digital Raster Graphic). Each scanned map is represented by a polygon in the layer and the map date, photo revision date, and photo interpretation date are found in the corresponding attribute record. This layer facilitates searching for DRGs which were created or revised on or between particular dates. Also useful for ascertaining when a particular map sheet was created.
