## Data Exchange

There are two options to exchange simulation results or complete scenarios using GREAT-ER: either to share scenarios with other users for further discussion or to export results for further analysis or inclusion in other documents.

The first is supported by providing an export / import functionality. Selecting Export, an export file will be created from the directory of the active scenario. The export file will then cover all scenario settings and additional data derived from the results and stored in the scenario's directory. Please note that the export / import feature does not include geographic data suich as river network (due to possible licence restrictions). Therefore users have to ensure that they are working on equal geographic data sets if they want to exchange (and work with) scenario data. Conversely an export file can be selected using the Import item and will then be added as a new scenario to the scenario database.

GREAT-ER provides some features for the second task - additional options are available by ARCVIEW within the expert mode. The item Report under the GREAT-ER menu writes a dump of all scenario data and all results to a specified file. Requested parts can be abstracted from this using a common text editor. The second option is to export a concentration profile for a selected river from a catchment: by selecting Analysis / Concentration Profile a tool will be activated. You have to select a stretch by clicking on the view. Moving downstream the C sim, internal values are collected per stretch. The collection will be displayed in a simple X/Y-profile. Because the chart display options of ARCVIEW are quite limited you have the option to export the profile data to create a smarter presentation using your favourite data plotting or spreadsheet program.

Additionally, it should be mentioned that the full set of simulation results are stored under the scenario directory within the files `Csim.dbf` (river) and `CsimSTP.dbf` (treatment plants). You may use copies of these files to further analyse the data.

Other options are available under ARCVIEW in the expert mode. The most important function might be to export the resulting visualisation onto a map by colouring the river stretches. This can be done quite comfortably using the ARCVIEW layout capabilities (mentioned above under section GREAT-ER and ARCVIEW).
