World Wind Geo: The Eclipse RCP Geobrowser

Welcome to World Wind Geo: The Eclipse Geo browser. The Geospatial Web or Geoweb is a relatively new term that implies the merging of geographical (location-based) information with the abstract information that currently dominates the Internet. World Wind Geo is an experimental geo browser built on top of:

• World Wind Java SDK - http://worldwind.arc.nasa.gov/java/ : Allows developers to embed World Wind technology in their own applications.
• Eclipse - http://www.eclipse.org/ : Eclipse is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes.

Our goal is to close the gap between GIS & SIS (Scientific Information Systems) by incorporating low/med/hi resolution GIS datasets from multiple sources: NASA, MS Virtual Earth, and others with the java NetCDF library for plotting/subsetting capabilities of scientific data.

World Wind Geo has the following fetaures:

• Interactive 3D navigation.
• Full support for WMS 1.1.x and 1.3.x using wizards.
• Over 500 real time weather data sets from NOAA and the Navy Research Labs.
• Limited support for KML: Ground overlays, screen overlays, and placemarks only.
• Support for animated ground overlays to visualize events over time.
• Scientific Data Plot/Subset capabilities with NetCDF.
• Open source: built on top of the World Wind Java SDK and Eclipse frameworks.
• Highly extensible: It uses the eclipse plugin framework to extend the user interface.
• Multi platform: built on proven standards: Java and Eclipse.

The NetCDF Viewer

NetCDF (network Common Data Form) is a set of software libraries and machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data. http://www.unidata.ucar.edu/software/netcdf/ . WW Geo bundles a NetCDF viewer for the following conventions:

• NetCDF File types: http://www.unidata.ucar.edu/software/netcdf-java/
• NetCDF conventions: COARDS, Models3, WRF, CF, and others (see link above).
• To use the viewer select "File/Open Dataset" or simply point the built-in web browser to any OpeNDAP/THREDDS data server such as http://dataportal.ucar.edu:9191/dods then click any dataset OpeNDAP link (The data will be displayed automatically on the NetCDF View).

Others

• Full support for WMS 1.1.x layers and 1.3.x animated or static layers.
• Limited KML support: Temporal/static Ground, Screen overlays and placemarks.

Requirements

• Graphics card with updated drivers. See http://worldwind.arc.nasa.gov/java/
• Java 1.5

WW Geo Main GUI Screen Shot

Here is a screen shot of the main user interface. The earth, moon, and mars are shown, the earth displays a sea surface temperature ground overlay obtained from a scientific NetCDF OpeNDAP dataset.

Known Issues

• OSX/Linux: The built-in web browser doesn't work yet. A patch using Mozilla/XULRunner is on the way.
• OSX: The WMS wizard server selection combo doesn't recognize built in server URLs.
