Program M3TOGIS

Summary

Reads read time steps of variables from a gridded I/O API file and writes them to multiple supported GIS-format-type "raster" (GRIDDED) files.

Usage

        setenv  GRIDFILE  <path name for input gridded file>
        setenv  FILELIST  <path name for input ASCII file-list>
        setenv  HDRDIR    <path name for BIL or FLT header files>
        setenv  IMISS     <missing value for INTEGER variables>
        setenv  RMISS     <missing value for  REAL   variables>
    

For each file in FILELIST

        setenv <file-name>  <path name>
    

Then

        m3togis [and answer the prompts]
    

where

${FILELIST} is list-formatted (quoted strings) with one output file per line, with

        <file-name> <vble-name> <date> <time> <layer> <type>
        

type is one of {BIL BIL2 BIL4 FLT, ZBIL, ZBIL2 ZBIL4, FLT, ARCI, ARCR, ARCE, ASCI, ASCR}
LEN( *file-name ) is at most 16
path-names are of the form <root>.[ flt | bil | bil2 | bil4 | hdr ]
header-file files are of the form ${HDRDIR}/<vname>.bil.hdr
