Figure 4.9, “Mrgelev input and output files” shows the input and output files for the Mrgelev program. The input files are a list of the ASCII elevated files (FILELIST) and optionally a list of PELV files created by Elevpoint (PELVLIST). In both files, the complete file name including path must be provided. When using the PELVLIST file, each file must match the corresponding ASCII elevated file. The program outputs a log file (LOGFILE), a merged ASCII elevated file (OUTFILE), a merged binary elevated file (PTSOURCE), and a report file (REPMRGELEV).
| File Name | Format | Description |
|---|---|---|
FILELIST |
ASCII | List of input ASCII elevated files including path and file name |
PELVLIST |
ASCII | List of input PELV files including path and file name; leave environment variable unset if not processing PinG sources

-
MRG_DIFF_DAYS: [default: N]This environment variable allows Mrgelev to merge files with data from different days.
-
Y: Allow data from different dates to be merged together
Mrgelev will use the environment variables
G_STDATE,G_STTIME,G_RUNLEN, andG_TSTEPto set the start date, start time, length, and time step of the output file. All input files must have the same starting time asG_STTIME, the same time step asG_TSTEP, and must contain more thanG_RUNLENsteps of data. For each input file, if it contains data to cover the actual episode requested byG_STDATE,G_STTIME, andG_RUNLEN, then the data for the actual episode will be used; otherwise, data starting at the first time step of the file will be used. -
N: Require all merged data to be from the same date
Mrgelev will determine the output file time period based on the latest starting input file and the earliest ending input file.
