This is an ESRI-ArcView project that has been customized with a graphical user interface (GUI) and which has sufficient functionality to become a spatial query and visualization tool for Across Trophic Level Systems Simulation (ATLSS) generated output data (fig. 1).

The overall goal is to provide an easy-to-use tool capable to access the vast amounts of data produced by the ATLSS models. The system allows users to display and integrate spatial and non-spatial information from different sources; interactively extract statistics for user-specified areas; produce outputs in form of maps, charts, tables, and reports.

Model descriptions are any time available at any time (fig. 2) for the user by simply selecting the species from the list of pictures, and clicking the button(s) (FCI in fig. 2) available on the lower part of the window.

ATLSS model output data can be compared by selecting the species of interest, two available hydrologic scenarios and time interval (continuous or discontinuous range of years). The result is a set of three comparison maps (CM) that can be subject to further investigations like displaying summarized index values by areas for each year (fig. 3).

Line graphs can also be generated from this information (fig. 4). Frequency histograms can also be generated for user specified spatial boundaries (fig. 5). The user can easily change the visual representation of the comparison maps (color scheme and classes of index values. The user can also add graphics (boundary and labels for a better representation of the analyzed area. Figure 6 shows an example of a user-defined label and graphic boundary. One of the available outputs is a quick print layout containing the comparison maps and general information about the data and the analysis.
