Since the middle 1970's, the U.S. Geological Survey (USGS) has
maintained a coal quality database of nationwide scope. Many of
these data have been released in USGS Open-File Reports or other
series. The present CD-ROM reports coal quality data for coal
samples that represent complete-bed thicknesses at various
localities. The data are presented on a whole-coal, as-received
basis, except for the oxides which are presented on an ash basis.
Documentation is provided in PDF files for all the data and
software included on this disc, including an index that allows
full-text searching across all of these files. This disc contains
analytical data for selected U.S. coal samples, descriptions of
the samples and their collection locations, descriptions of
analytical methods and sampling techniques, a description of the
database format, and bibliographic references.
System Requirements
This CD-ROM was produced in accordance with the ISO 9660
standard. While the data and text files are accessible by any
computer system recognizing this standard, the data manipulation
and display software (LandView III) requires a Windows (3.x, 95,
or NT) environment. Although the software will run on a system
with as little as 4MB of RAM and a 1X CD-ROM drive, larger memory
and a faster drive will enhance performance.
Getting Started
PLEASE NOTE: If your computer system has any removable-media
drives in addition to your CD- ROM drive, ensure that there is a
piece of media in the drive when invoking LandView III. Otherwise,
an error message will occur.
1) Under Windows, run the program: "D:\INSTALL\Setup.exe" where
"D" is the letter of your CD-ROM drive. Wait until all of the
icons have been placed in the program group or folder. Then
simply execute the LandView III program.
2)  Install the MARPLOT fonts by choosing Fonts from the Windows
Control Panel, then "Install new Font" from the File menu (in
Windows 3.1, press the Add button).  Then choose the directory
where LandView has been installed (usually C:\LV3).  The fonts
MARPLOTP and MARPLOTD should appear in the font list window.
Press the "Select All" button, and then the OK button.
3)  LandView III is designed to run in Windows 95 and Windows NT.
You can, however, run it in Windows 3.1 if you install the 32-bit
processor, called WIN3S.  To install WIN32S, go to the
\INSTALL\WIN32S\DISK1 directory on the LandView CD, and run
SETUP.EXE.  (Note:  do not run _MSSETUP.EXE or _MSTEST.EXE).  If
you are running Windows from a network file server rather than
from your local hard drive, you may need the assistance of your
network administrator to install WIN32S.
Quick-Start Tutorial
Included on this CD-ROM is a "Quick-Start" tutorial on how to use
LandView III to search for specific information from the Coal
Quality Database. The nine pages comprising this tutorial are
contained in a "pdf" file that can be printed and used as a guide
to understanding the basic functions of LandView III.
LandView III - A Guided Tour
In addition to the "Quick-Start" tutorial, a more in-depth
examination of the various LandView III capabilities is available
in the pdf document entitled, LandView III - A Guided Tour. This
guide explores more of the graphical and mapping facilities of
LandView III.
LandView III Documentation
LandView III comes with several documentation and tutorial files:
LandView III Guided Tour (in PDF format),  LandView III Help (in
both PDF and Windows Help file formats), MARPLOT user manual and
technical documentation (in PDF format), and MARPLOT Help (in
Windows Help file format).  The Adobe Acrobat Reader for viewing
PDF files is included on this CD.
Introduction to the LandView (tm) III - Version 1.0, October,
1997
LandView III is a desktop mapping system that includes database
extracts from the Environmental Protection Agency, the Bureau of
Census, the U.S. Geological Survey, the Nuclear Regulatory
Commission, the Department of Transportation, and the Federal
Emergency Management Agency.  These databases are presented in a
geographic context on maps that show jurisdictional boundaries,
detailed networks of roads, rivers, and railroads, census block
group and tract polygons, schools, hospitals, churches,
cemeteries, airports, dams, and other landmark features.
LandView III version 1.0 Notes
The maps and data in LandView III, as in its predecessor LandView
II, are divided into 10 geographic areas, each on its own CD-ROM,
plus an additional CD covering the entire United States (see
below for a list of states on each CD).
The detailed networks of roads, rivers, and railroads comes from
the Bureau of Census TIGER/Line 1995 files, and are present on
CDs 1-10, but are absent from the national CD (#11).  (Since the
LandView Guided Tour refers to the map of Prince William County,
VA, that map, as well as the maps for the District of Columbia
and the State of Delaware, is included  on the national CD.)
The national CD has been augmented by the addition of major roads
from the Department of Transportation (refer to the Help system
under "U.S. Highways" for more details), and major streams and
rivers from the U.S. Geological Survey 1:2 Million scale Digital
Line Graph (DLG) files.
The Population Estimation feature now offers two methods, one
that uses Block Group Centroids (like LandView II), and another
that uses Block Group Polygons, and prorates the population
statistics based on the land area within the radius.
