World Wind Geo: The Eclipse RCP Geobrowser

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 - Allows developers to embed World Wind technology in their own applications.

Eclipse - Eclipse is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes.

Goal of World Wind Geo: The Eclipse RCP Geobrowser 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.

Ghostscript

Ghostscript is a package of software that provides:

• An interpreter for the PostScript (TM) language, with the ability to convert PostScript language files to many raster formats, view them on displays, and print them on printers that don't have PostScript language capability built in;
• An interpreter for Portable Document Format (PDF) files, with the same abilities;
• The ability to convert PostScript language files to PDF (with some limitations) and vice versa; and
• A set of C procedures (the Ghostscript library) that implement the graphics and filtering (data compression / decompression / conversion) capabilities that appear as primitive operations in the PostScript language and in PDF.

Ghostscript is written entirely in C, with special care taken to make it run properly on a wide variety of systems, including MS Windows, Apple MacOS, the wide variety of Unix and Unix-like platforms and VMS systems.
