Download Geoeas

The first order of business in any data analysis is to become familiar with the data set. You will
use a combination of statistics and graphical displays to look at the range and shape of the
frequency distribution, to look for data outliers which may be erroneous or unrepresentative, to
look at the "spatial coverage" of the data, and to look for spatial patterns in the data.
Begin by taking a look at a map of the data produced by the program Postplot. Assuming that
you have already copied the software and data into a directory called Geoeas on your hard disk,
and have used the command "CD \Geoeas" to access the directory, you can run Postplot either
by:
(1) using the DOS command C:\GEOEAS> Geoeas <enter> to enter the system menu, moving
the cursor to the Postplot option with the arrow keys, and pressing <Enter>, or by
(2) running the program directly from DOS by typing the command C:\GEOEAS> Postplot
<enter>.
When the program begins execution, it first displays a screen with introductory information.
When you press a key to proceed, you will see the program main screen and menu, as displayed
in Figure 4-1.
The bottom line on the screen provides the list of available options. The first five move you to
an area on the screen (or to a new screen) where you can input or select program parameters. The
Execute option starts the actual processing portion of the program, and Quit moves you to the
preceding menu (or out of the program). All menus in the system operate in a similar way:
options are selected by moving the highlighted bar to the desired option name with the arrow
keys and pressing <enter>, or by typing the first character of the option name.
