ILIADS 3.0 provides the data management capabilities to access CxP-vetted lunar data sets from the LMMP-provided Data Portal and the LMMP-provided OnMoon lunar data product server. (LMMP stands for Lunar Mapping and Modeling Project.) It also provides specific quantitative analysis functions to meet the stated LMMP Level 3 functional and performance requirements specifications that were approved by the CxP.

ILIADS 3.0 is a rich client (aka, thick client) lunar Geospatial Information System (GIS) software application. It is a redesigned software framework and architecture that leverages GSFCs experience developing the ILIADS 2.0 core software. Specifically, ILIADS 3.0 is built upon ILIADS 2.0.

The purpose of ILIADS 3.0 is to provide an integrated, rich client lunar GIS software application. Most significantly, the objective in designing and developing ILIADS 3.0 was to provide a flexible and expandable software framework that readily enabled new features and functions to be integrated into ILIADS driven by the science and engineering user community. To contribute to the decision support process, ILIADS 3.0 also provides interfaces to readily enable interoperability between ILIADS 3.0 and other NASA-developed lunar information systems whenever it may become required to interface ILIADS with such systems.

By building upon Goddard’s IRC core framework, ILIADS is also well suited to being readily integrated with future lunar surface system assets (e.g., crewed rovers, spacesuits) as an embedded system application. ILIADS 3.0 provides cross-platform support and thus executes on a diverse suite of computing platforms that are used by NASA scientists and engineers. The application is designed to provide author ized/ authenticated users with the ability to use the Internet to securely, yet easily, identify and locate geographically distributed sources of vetted lunar data products that have been derived from US and international lunar spacecraft missions. It can query the data catalogs of these sources to identify available lunar data products and the metadata associated with them. The software uses standard OGC (Open Geospatial Consortium) WMS, WCS, and WFS (Web Map Service, Web Coverage Service, and Web Feature Service) services to access mapped lunar delta products from these sources so that they may be processed by ILIADS 3.0 and rendered as multiple semi-transparent raster or vector visualizations, so that the lunar data product information is readily understood in the context of one another.
