Elipgrid-PC Hot Spot Probability Calculations

Brief Description of the Program

ELIPGRID-PC is a program for the design and analysis of sampling grids for locating elliptical targets (e.g., contamination "hot spots"). It computes the probability of success in locating targets based on the assumed size, shape, and orientation of the targets, and on the specified grid spacing. It can also be used to compute a grid spacing from a specified success probability, compute cost information associated with specified sampling grids, determine the size of the smallest hot spot detected given a particular grid, and create graphs of the results.

Requirements

A PC running MS-DOS 5.0 or higher or any recent version of Windows. ELIPGRID-PC has been succesully run in DOS, Windows 3.11, and Windows 95. It should also run in Windows 98 or Windows NT.

Instructions for Downloading, Installing, and Running ELIPGRID-PC

The ELIPGRID-PC files on this server were packaged into ZIP archives using PKZIP 2.04g.

• Click on elipgrid.zip to download a regular ZIP file, or
• Click on elipgrid.exe to download a self-extracting ZIP file.

To install ELIPGRID-PC from the self-extracting ZIP file move the elipgrid.exe file to the desired directory and type "elipgrid" to extract the archived files into the present directory or "elipgrid -d" to extract the files into an ELIPGRID subdirectory. You may then delete elipgrid.exe.

To run ELIPGRID-PC, go to the elipgrid directory and type the command "egpc". To view command line options, type "egpc ?". You should read the file "README" and view the online help screens for further information on how to use ELIPGRID-PC.
