049 PPT Slide
050 Part IV
051 Applications vary by the functionality of their Front-Ends
052 Applications vary by how they are composed from modules
053 The modules can interact with each other in different ways:
054 Applications vary on how the Front-End interacts with the 
    Middle-Tier
055 Landscape Management System
056 LMS Objectives
057 LMS: Changes in Vegetation
058 LMS: Changes in Vegetation
059 LMS Front End
060 Data Retrieval
061 PPT Slide
062 WMS based Visualizations
063 Implementation of LMS
064 Running LMS
065 To run LMS
066 Client code
067 1.start runCasc2d;
068 2. casc2 starts in a new thread, uploads data to its web server 
    and sends "done" event to Edys;
069 3. casc2 waits for new data from Edys; Edys downloads data and 
    runs `till the first rain event
070 4. casc2 waits for data; Edys uploads data, sends event "done" and
     quits
071 5. runcasc2 fetches data from remote web server
072 6. Casc2d detects new data and resumes execution
073 7. Casc2d completes the rain event and writes new data; runCasc2d 
    detects new data and sends event to Edys
074 8. Edys fetches data from the remote web server and starts; casc2d
     waits for new data
075 9. This cycle is repeated `till all rain events are processed
076 10. Casc2d quits, final run of Edys begins
077 11. Edys terminates. All data are on the WinNT side  and can be 
    visualized using WMS tools.
