Hardware requirements
The minimum hardware required is a Unix workstation (at least a Sparc2) supported by ESRI's ARC/INFO software, preferably with 64 Mb RAM and 1000 Mb free disk space. This must be linked to a graphics printer or plotter set up to work with ARC/INFO if hardcopy of output is required.
Software requirements
The software required is a current ARC /INFO v.7.x or later user license.
The Watermarque programs and data are supplied on a CD-ROM. The program is installed on a number of subdirectories on the disk, in a directory stipulated by the system administrator. These subdirectories include:
A map library called watermarque must be created by editing the $ARCHOME/TABLES/LIBRARIES file. This library must contain the Digital Chart of the World (DCW) data, obtained by the user if outside the Department of Water and Sanitation. The library can be situated anywhere on the system, not necessarily in the same location as the WaterMarque subdirectories.
The user password file must be added, to allow different users access to the system. This is not a security device but a way to allow several users to use the program without conflict, saving analyses files and plots to separate directories. It allows the system administrator to monitor the disk space utilised per user or user group, keeps records separate so that they can be effectively archived when a project terminates or can ensure that more heavily used files are backed up more frequently if necessary.
The file :
...directory/wmrq/ptool/icons/login
will contain individual researcher's names with their chosen passwords, or project names should user groups wish to work within a single set of records.
Before opening an ARC session, the canvas colour must be set to white, to give a screen view that resembles the output, i.e. black text will appear black on screen and in plots. The global WMSYS variable must also be set so that WaterMarque knows where to find system files.
The system administrator may edit the global login file in Unix to set these variables. If this is not desirable, then:
setenv CANVASCOLOR WHITE
setenv WMSYS <path/to/watermarque>
Followed by:
arc
and finally,
wmrq
WaterMarque has a menu driven interface which does not permit editing of datasets within the program. This is a desirable feature where several users have access to the data. Any editing of data must occur outside the Watermarque interface using ARCEDIT to edit the spatial data (such as rivers or monitoring point locations) and Unix or ARC/INFO to edit data pertaining to time series, water quality or flow data.
To run Watermarque, first start ARC/INFO by entering
arc at the Unix
prompt. Once ARC/INFO has started the following ARC prompt will appear:
arc:
At this stage, if an error occurs i.e. product not licensed or command not found , or the arc prompt does not appear, contact your system administrator.
Start WaterMarque typing wmrq at the arc prompt, thus:
arc: wmrq
A few seconds will pass while the screen is cleared and the opening window is displayed. This opening window requests a username and password. While the username can be typed in if necessary, by default it will be your Unix login name. The password is not your Unix password, and will usually be the same as your name. Moving between the two menu fields (username and password) is accomplished by using the <Tab> key or the mouse.
Acceptance of the username and password is indicated by hitting the<Enter> key on the keyboard.
To exit the system immediately, click on the Exit button.
