#1 TSEO Toolbox for Spatially Explicit Optimization
TSEO assumes a predefined spatially explicit model using a
raster-based data structure for the spatial information
to be used in the optimization process, as coded using
SMODENV.
General objective of the toolbox is to identify optimum
spatial patterns (such as landcover or land use in a
landscape model) that maximize a certain permormance
criterion.
The desired performance criterion is rarely part of the
simulation model. Because of this, for application of
the optimization toolbox, the simulation model has to
be modified to support the optimization toolbox with
required information. This information relates to the
performance criterion to be maximized. Variables used
in the performance criterion are not usually part of
the model, as these variables often calculate
aggregated indicators of the model system, such as
integrals or sums of state variables. Or, these
indicators reflect on boundary conditions or
contraints, which are to be met during simulation time.
Within a user code part of the model spatial variables
are to be calculated that can be fed into the
performance criterion using TSEO, these are written
into a sptail database using SMODENV.
Parts of this toolbox interact with the spatial
modeling environment, other parts support analysis of
the results within the geographic information system
ArcVIEW. The toolbox is structured in three parts:
- A geographic information system that is used for
visualization of the results and offers a graphical
front end for the most important functions of the concept.
- A spatial explicit dynamic system, that is capable of
simulating environmental processes on a raster-based
data structure.
- Several programs that set up the toolbox for
spatially explicit optimization of dynamic systems.
These programs offer the functionality
The TSEO command-line interface supports a simple
access to the programs of the toolbox.
Exchange of data and maps between these three parts is
performed within a database structure using ArcVIEW
ASCII raster map format. Spatially explicit simulation
models that are capable of reading and writing the
model output in this format are therefore applicable in
the toolbox.
