Libraries

OEF libraries (JAR files) are arranged in multiple tiers, from low-level generic utility libraries and file format readers, to high-level data model management, user interface components, and visualization.

Utility libraries

Low-level utility libraries provide generic features that are independent of OEF. The libraries may be used without loading any of the other OEF libraries.

Library	Depends upon	Description
SDSC_util     edu.sdsc.io     edu.sdsc.io.csv     edu.sdsc.util.arrays     edu.sdsc.util.color     edu.sdsc.util.debug     edu.sdsc.util.event     edu.sdsc.util.geom     edu.sdsc.util.named     edu.sdsc.util.properties     edu.sdsc.util.range     edu.sdsc.util.text	none	Generic utility classes for CSV file I/O, dynamic arrays, property maps, formatting and parsing, and geometry.
SDSC_projection     edu.sdsc.projection	jhlabs.com Java Map Projection package to handle "proj4" style projections	Classes to define projections and convert between them.

File format I/O libraries

Mid-level file format libraries each perform I/O for specific vendor or community standard file formats. These libraries may require one or more other libraries but they are not OEF-specific. Wherever possible, all features of the file format are exposed.

Library	Depends upon	Description
SDSC_census     edu.sdsc.census	SDSC_util	Classes to read US census summary files.
SDSC_esri     edu.sdsc.esri.arcgrid     edu.sdsc.esri.shapefile	SDSC_projection, SDSC_ogc	Classes to read ESRI's Shapefile and Arc Grid/Info files.
SDSC_geosoft     edu.sdsc.geosoft.gxf	SDSC_projection	Classes to read GXF grid format.
SDSC_ogc     edu.sdsc.ogc.prj	SDSC_projection	Classes to read OGC Well-Known Text (WKT) .prj files.
SDSC_usgs     edu.sdsc.usgs.neic	SDSC_util	Classes to read USGS NEIC earthquake epicenter files.

Data model libraries

Mid-level data model libraries provide spatial data and metadata abstractions that may be used to hide low-level file format details from higher level code.

Library	Depends upon	Description
SDSC_data     edu.sdsc.data.core     edu.sdsc.data.model     edu.sdsc.data.process	SDSC_util	Base classes and interfaces for spatial data, including grids, point lists, polygon lists, and directed graphs.

User interface and visualization libraries

High-level libraries provide OEF-specific functionality for buildilng cross-platform appllications, managing multiple windows, building sessions that combine data and properties into a multi-layered scene, and presenting a user interface and control panels to interact with properties and visualize the data in 3D.

Library	Depends upon	Description
SDSC_app     edu.sdsc.app.application     edu.sdsc.app.document     edu.sdsc.app.mvc     edu.sdsc.app.session     edu.sdsc.gui.component     edu.sdsc.gui.datatransfer     edu.sdsc.gui.layout     edu.sdsc.gui.plaf     edu.sdsc.gui.window	SDSC_data, SDSC_util	Base classes and user interface components for building cross-platform applications.
SDSC_oef     edu.sdsc.geon.oef.app     edu.sdsc.geon.oef.gui     edu.sdsc.geon.oef.io     edu.sdsc.geon.oef.util     edu.sdsc.geon.oef.vis	all of the above plus NASA WorldWind.	OEF-specific user interface support and visualization components.
