Unformatted text preview: Sheet1 Page 1 THE GEOID99 README FILE----------------------- Version: January 12, 2000 das/drr The GEOID99 GEOID MODELS------------------------ You have received these models on CD-ROM, or downloaded them from the National Geodetic Survey (NGS) web site or the NGS FTP site. Files you may have received include: INTG.EXE (PC) or The geoid interpolation program (source code is INTG (Sun) INTG.FOR (PC) or INTG.F (Sun)) XNTG.EXE (PC) or Program for extracting, translating (ascii/binary) XNTG (Sun) and yielding statistics of geoid files (source code is XNTG.FOR (PC) or INTG.F (Sun)) DOSXMSF.EXE (PC) 32-bit DOS extender (needed for running INTG.EXE on a 386 PC) The following file names are valid for PC or Sun (if, however, you downloaded the ASCII versions of these files, the suffix will be ".asc" rather than ".bin"): g1999u01.bin GEOID99 grid #1 for CONUS (40-58N, 230-249E) g1999u02.bin GEOID99 grid #2 for CONUS (40-58N, 247-266E) g1999u03.bin GEOID99 grid #3 for CONUS (40-58N, 264-283E) g1999u04.bin GEOID99 grid #4 for CONUS (40-58N, 281-300E) g1999u05.bin GEOID99 grid #5 for CONUS (24-42N, 230-249E) g1999u06.bin GEOID99 grid #6 for CONUS (24-42N, 247-266E) g1999u07.bin GEOID99 grid #7 for CONUS (24-42N, 264-283E) g1999u08.bin GEOID99 grid #8 for CONUS (24-42N, 281-300E) g1999a01.bin GEOID99 grid #1 for Alaska (60-72N, 172-204E) g1999a02.bin GEOID99 grid #2 for Alaska (60-72N, 202-234E) g1999a03.bin GEOID99 grid #3 for Alaska (49-61N, 172-204E) g1999a04.bin GEOID99 grid #4 for Alaska (49-61N, 202-234E) g1999h01.bin GEOID99 grid #1 for Hawaii (18-24N, 199-206E) g1999p01.bin GEOID99 grid #1 for Puerto Rico/VI (15-21N, 291-296E) To Install: 1) Make a subdirectory on your hard disk. 2) Copy the various geoid files into that subdirectory. You need not put the geoid files in the same directory as the programs. (If you have also received G99SSS model files, you may safely place them in the same directory as GEOID99, if you like.) 3) If you are using a PC, check your AUTOEXEC.BAT and CONFIG.SYS files to insure compliance with the following notes: Note 1: If you are running a 16-bit PC (such as a 386), then DOSXMSF.EXE must either be present in the same directory as INTG.EXE, or, it must be in a directory in your DOS PATH environment variable (such as: c:\dos). DOSXMSF.EXE may be freely reproduced and distributed, without royalty. Sheet1 Page 2 Note 2: You must have a statement FILES=25 (or a number greater than 25) in your CONFIG.SYS file. To Execute (PC or Sun) Type INTG , and follow the prompts. To Terminate You can stop the program at any time by the Control C key combination. BUT, PLEASE DON'T START YET. PLEASE KEEP READING THIS DOCUMENT. Check The Byte Counts of all Downloaded Files--------------------------------------------- Before beginning, it will be useful to ensure that all files you have received are the correct size. (Download problems are often manifested by incorrect byte counts in the files). Check with the list below to make sure your files match these numbers...
