95/98/XP operating system. Once unzipped, double click the SETUP.EXE file to 
start the installation process. It is suggested that the application be installed in the 
C:\VOL3D directory. The original zipped file can be deleted to regain disk space. A 
fast Pentium machine with 256 mb ram and 1 gb disk drive will prove useful. 
USING THE CHESAPEAKE BAY INTERPOLATOR 
PROCEDURE FOR USING THE VOL3D INTERPOLATOR 
Begin using the VOL3D software by double clicking the VOL3D.EXE icon on the PC. 
The first screen provides 7 buttons (Geography, Parameter, Data Import, Interpolate, 
Math, Graphics, and Reports) that step the user through the interpolation, graphics, 
and reporting process. Also on the first screen, is a Data File Creation Tool , that can 
be used to create VOL3D compatible data files from an external ACCESS data base. 
The ACCESS data base needs to contain data necessary for interpolation, as identi¬ 
fied on Figure D-2. Essential data fields include STATION, LONGITUDE, 
LATITUDE, DEPTH, and VALUE. Other fields, including SAMPLE_DATE, 
PARAMETER name, LAYER, Qualifier (<, >), CRUISE, and CRUISE_ID, provide 
data that can be used to select or subset the monitoring data by cruise, layer, or date.
