Associated Projects: Component of the ATLSS Program

Overview & Status: This project concerns the continuation of the development of the ATLSS data viewer system (DVS), a customized application based on ESRI-ArcView 3.2 that provides capability of displaying and processing, in a Geographic Information System, the output of some ATLSS submodels. Currently, output from the hydrology model, and spatial index values for the white-tailed deer, Cape Sable Seaside sparrow, wading birds, American alligator, and snail kite, for three hydrologic scenarios (F2050, C1995, AltD13r), and 31 years (1965-1995) can be viewed and spatially analyzed to support Everglades restoration planning. The ATLSS data viewer capability has been expanded, in DVS Version 2.0, to include output from other ATLSS models (fish dynamics models, ALFISH) and will be extended to the snail kite individual-based model, EVERKITE, and Cape Sable sparrow model, SIMSPAR), and will provide users with the possibility to input empirical data in order to determine the degree of correlation between models output and empirical data. Users are able to import into the DVS a set of locations (UTM, decimal degrees, or degree, minute, second coordinates), extract cell values from model outputs, and display the result or export it to external applications like MS Excel or the ATLSS Model Validation tool. Other upgrades include development of DVS's capability to input user's empirical data in order to determine the degree of correlation between models output and empirical data. Additional code will be necessary to allow users to import into the DVS a set of locations (UTM, decimal degrees, or degree, minute, second coordinates), extract ATLSS model values, and display the result or export it to external applications like MS Excel or the ATLSS Model Validation tool.

Needs & products: Managers or decision makers who need to support decision-making, and scientists who need to evaluate hydrological or ecological impacts using ATLSS model outputs benefit from the ATLSS data viewer because it allows the access, display, and analysis of the vast amount of data produced by ATLSS models with a user-friendly graphical interface. With the increase of the number of sites capable to run ATLSS models locally, the ATLSS DVS becomes the first tool in displaying the results of new runs. The DVS is able to provide procedures to import raw data generated from the models into a ESRI-grid format, which is used for displaying and performing spatial analysis, and integrate this data with other data sets in one, largely used GIS environment like ESRI ArcView 3.2. To support users of ATLSS DVS, task-oriented tutorial exercises and on-site additional training sessions have been provided, as well as a web-based user's support center.

Application to Everglades Restoration: The ATLSS DVS is essential to viewing ATLSS output, so that the ATLSS models can be used in CERP evaluations. The ATLSS DVS has been delivered already to Everglades National Park and the U. S. Fish and Wildlife Service for this purpose.
