    File system layout and configuration

    Simtrap can be installed and maintained under a single root directory, or with file systems distributed across different partitions and disk within a single NFS file system. A single-site system, with a small set of maps and a single satellite image will occupy around 100 MB of disk space; for larger areas, multiple sites, several satellite images and DEM coverage as well as scanned background maps, this can quickly approach 1 GB of disk space requirements.

    In a standard installation, assume a root directory $SIMTRAP. This directory would then contain:

    drwxrwxr-x  10 user    ess       512 Jul 30 09:15 ../
    -rw-rw-r--   1 user    ess       897 Mar 16 09:55 .aca_licenses
    drwxrwxr-x   4 user    ess       512 May  6  1998 bin/
    -rw-rw-r--   1 user    ess       878 Mar 16 09:55 CONFIG
    -rwxrwxr-x   1 user    ess   5980160 Apr  6 16:43 Ssun5*
    drwxrwxr-x  14 user    ess       512 Jul 29 15:39 data/
    drwxrwxr-x   3 user    ess       512 Jul 27 10:00 defaults/
    drwxrwxr-x   2 user    ess       512 Apr  9 15:44 logs/
    drwxrwxr-x   2 user    ess       512 Jul 29 14:59 output/
    Ssun5 is the executable programme.

    The CONFIG file controls the location of all other files by specifying the location of the data and defaults directories.

    The Doc directory contains release notes, READ_ME files etc., and the

    output directory contains temporary output and scratch files of the system.

    bin contains architecture specific subdirectories (e.g., sun5, ibm, hp, lnx with auxiliary programs such as convert, used for the conversion of XWinDumps into GIF files (see also: Hardcopy output of maps and model results.

    log contains a set of log files that are created at startup and during systems operation that can be used for diagnostic purposes.

    plot contains the output from the plot option for the model output display pages.
    WARNING: files in this directory are not removed automatically; they will keep accumulating everytime the plot function is used. The user is responsible for their maintenance and eventual removal.

    data is the root of the data directories. It contains the following subdirectories and files:

    drwxrwxr-x   2 user    ess       512 Feb  7 13:01 KB/
    drwxrwxr-x   2 user    ess       512 Nov 18  1998 bitmaps/
    drwxrwxr-x   5 user    ess       512 Jul  5 14:46 cliser/
    drwxrwxr-x   2 user    ess       512 Feb  1 15:49 descriptors/
    drwxrwxr-x   2 user    ess       512 Feb  8 13:27 explain/
    drwxrwxr-x   2 user    ess      1536 Jul 29 12:02 fma/
    drwxrwxr-x   2 user    ess      1024 Feb  3 08:48 icons/
    drwxrwxr-x  22 user    ess       512 Jul 29 11:38 maps/
    drwxrwxr-x   4 user    ess       512 Apr  6 14:25 objects/
    drwxrwxr-x   2 user    ess       512 Dec 17  1998 rasters/
    drwxrwxr-x  14 user    ess       512 Jul 27 13:21 sim_results/
    drwxrwxr-x   2 user    ess      1024 Jul 27 13:22 temp/

    fma contains all the FMA-Files of the scenarios.

    objects contains the following subdirectories:

    drwxrwxr-x   2 franz    aca          512 Aug  6 12:09 scenarios/
    drwxrwxr-x   7 franz    aca          512 Jun 10 13:47 snet/

    scenarios contains files which describe an entire Simtrap senario per file. snet contains the basic Dynemo-scenarios and files.
