makes it easy to separate the logical layer and data layer thus
increasing its flexibility. This database was also chosen
because it can easily be transferred to a more powerful database
when extra functionality is needed.
2.5 TCP/IP Protocol
The TCP/IP protocol is the communication protocol that is used
in the system to transmit data between the server computer and
any number of client computers over an Internet connection.
The TCP part of the protocol establishes the connection
between computers and exchanges streams of data. The IP part
of the protocol addresses the packages of data and drops them
into the system so that they can be delivered to the appropriate
computer.
3.0 INTERFACE FOR INTERNET USER
3.1 User Access and Main Page Layout
The general public and forest fire managers are the two
potential users of the WMMS. The forest fire managers have
the capability to use this system like a public user but also have
the added ability to control, update and monitor the system.
When an authorized user is logged onto the system, the
program will check the user's access rights and make available
the appropriate toolbars. For example, when a manager is
logged onto the system, the Manager's Toolbox will be
available in addition to the tools available to the public user.
The tools reserved for managers are under the heading labeled
Manager's Toolbox on the main page of the website.
A sample screen capture of the WMMS is shown in Figure 3.
This screen capture depicts the setup for a user with managerial
capabilities. This sample can be accessed from the following

The left hand side of the screen shows the reference map and
legend which contain the possible layers that can be added to
the display. The center of the screen shows the province of
Alberta which can be panned or zoomed into in order to show
the user a more detailed map. The right hand side of the screen
displays the possible tools that can be used to assist in modeling
wildfires. A list of all possible tools includes the Fire/Hotspot
Report Tool, Trajectory Tool, Prometheus Tool and Manager’s
