Each PC ARC/INFO coverage consists of a directory containing many files. The entire coverage directory contents should be copied. The MS-DOS XCOPY command may be used, as in the following example:
XCOPY D:\DATA_ARC\A_STATE C:\DIGATLAS\A_STATE /S
XCOPY D:\DATA_ARC\ADAIR C:\DIGATLAS\ADAIR /S
XCOPY D:\DATA_ARC\ATOKA\ROADS C:\DIGATLAS\ATOKA\ROADS /S
XCOPY D:\VIEWS C:\DIGATLAS\VIEWS /S
The above examples would copy all the statewide coverages (except the shaded-relief image), the Adair County coverages, the roads coverage from Atoka County, and all view files from the D: CD-ROM drive to the C: hard disk drive. The statewide coverages together require about 17 megabytes of hard disk space. The counties range from about 5 to 19 megabytes in size. The shaded-relief image is just under 100 megabytes in size.
A simple batch-file utility is provided, named \COPYTOHD.BAT, which automates the above process. To run this utility, make the CD-ROM drive the active drive and type COPYTOHD at the DOS prompt. The program will provide usage instructions.
Another way to improve system performance is to avoid displaying large polygon coverages as solid-filled polygons. The polygon boundaries may be displayed much more quickly than solid-filled polygons, but may not be queried for polygon attributes. The two alternate ways of displaying polygons are illustrated by the watershed boundaries and watersheds themes, both of which display polygons from the WATRSHD coverage. Polygon data sets that may display slowly are: ADMINBD, CENSUS, TNRGSEC, and WATRSHD.
All displays will work in standard 16-color VGA mode. However, several data sets will display much better in a 256-color VGA mode. In particular, the shaded-relief image is best displayed in a VGA mode that will support 256 levels of gray.
System performance and usability also may be improved by adjusting the mouse sensitivity using the Preferences option from the File pulldown menu.
