Project management

A project is an aggregation of geographic themes (maps, points) and modeling themes (fuzzy-models, neural networks, dynamic models). The user can use projects to simplify the handling of data and models. Firstly he can create a new project with the project name in P1. The project name must be unique. All maps are stored in a HDF file with the same name as the project and the extension h5. That implies that the HDF file also must be unique.

In an open project all maps, point themes or line themes can be stored simply by using the "add"-command. In the same way the models can be stored.

To open a project please go into the selected project directory and click at any file in this directory. Then use the open button and the project will be opened. SAMT can handle only one project in one session. If you want to use a different project please close SAMT and start it again.

For example: to open the project "schreiadler1" please go into this directory and click to fuzzy or point or scripts. Then use the open button (click two times) and the project will be opened.

The project management is convenient and should be used to store all basic maps and all models. The modeler get closed view to all relevant data and models of one simulation. This is useful even if the model was not used for a while.

Complex_models

Complex_models are a new type of models in SAMT. Complex_models allow the use of a potentially infinite set of model parameters. To create a new complex_model a new tool "config1" was included in SAMT. The config1 simplifies and supports the model creation, including additional files (Makefile, includes, skeleton for main etc.) and compilation of a new model. To use the config1 please create a new model in $SAMTHOME/modell/model_name and goto this directory. At this place use the config1. For example a filter model with the spatial input (hdf and gridname) and the filter parameter:

After model development the model can be included in the project using Project/Add_cModel. This copies all needed files (model_name.xcfg and model_name.values) in the project directory. The configuration will be loaded from the project directory. This allows the use of one model in different projects.

Starting a complex_model pops up a simplified control window which gives the opportunity to change the model parameters and to start the model. The result of a simulation of a complex_model will be automatically included in the grid tree of SAMT with the model_name. The next picture shows the control window for the filter example.
