3 Software structure and functions
Within the software different user profiles, workspaces, projects and filesets
containing different files can be created.
- User: Each user can be added by creating a new user account with the
user name and a specific workspace.
- Workspace: Each user has a workspace that can be created anywhere on
the harddrive. This workspace contains all projects and project files. All
changes that are made within the software will lead to according changes
within the working space. Please do not change the filestructure or files
within the working space as this may result in problems when opening the
project in the software afterwards.
- Filesets: Files are organized within filesets that can be created within
the user interface. Any created fileset will result in the creation of a folder
accordingly within the working space. Within these filesets (and folders
within the working space) all files can be organized.
- Files: Files are GIS data layers that can be ?? into or ??xported from
the filesets in different formats.

The software has been designed to support the different GIS data file formats
asci, EsriGrid and geotiff. All imported files are links to the original files but hard
copies can be created within the programme if desired. All functions are at first
added to the file and have to be executed in a second step after all the settings have
been made by the user.
Generally all functions within the program are classified within three
- Information Reader Functions: The functions within the category
information are functions that do not change the file but give information
about the present file e.g. mean, standard deviation or median (read-only
- Option File Changer Functions: The functions that can be chosen within
the option file changer environment allow to create simple copies of the GIS
layers or to change the present GIS layer by applying certain procedures,
e.g. normalization or categorization (read and write functions).
- Connection Functions: Connection functions integrate more than one GIS
layer in a mathematical algorithm and result in the creation of new files
(read and write functions with more than one file). These functions include
for example subtractions, summations or calculating the mean value over
different GIS layers. Furthermore this category includes functions that
calculate correlation coefficients over different files.

Information readers, options and connections have to be added to the files before
they can be applied. To add a function select one or more files go to Edit→Add in
the menu and select information reader, option file changer or connection function.
You can also right click on one file, go to Add and select the specific function
category from the context menu.
|Figure 5||Add information readers, options and connections|
After adding functions to your files they will be added in the filetree
to the specific files. Connections will be in line with the other raster files.
Functions have to be executed after being added to your filetree. To execute
functions go to Edit→Execute in the menu and select inforreader, options or

When adding a function to your filetree, the function symbol is first displayed in
grey and after being executed they are displayed in color.
