Osgeo Live CD/DVD provides a collection of open source geospatial software tools that can be run from a live bootable DVD or USB drive without installing anything. It contains applications for storage, viewing, analysis and manipulation of geospatial data. OSSIM is a high performance open source software for remote sensing, image processing, GIS and photogrammetry. It supports parallel processing, sensor modeling, map projections and advanced image processing. OssimPlanet builds on OSSIM and OpenSceneGraph to provide 3D geospatial visualization capabilities and supports various data formats and services. PlanetSasha is a project to develop a plugin for OssimPlanet to interface with other open source GIS software like Grass and Q

2. - What is it?
OSGeo-Live is a self-contained bootable DVD, USB thumb drive or Virtual
Machine based on Xubuntu (xfce as desktop manager), that allows you to try a
wide variety of open source geospatial software without installing anything. It is
composed entirely of free software, allowing it to be freely distributed, duplicated
and passed around.
It provides pre-configured applications for a range of geospatial use cases,
including storage, publishing, viewing, analysis and manipulation of data. It also
contains sample datasets and documentation.
To try out the applications, simply:
1. Insert DVD or USB thumb drive in computer or virtual machine.
2. Reboot computer. (verify boot device order)
3. Press "Enter" to startup & login.
4. Trial applications from the "Geospatial" menu.

3. - Where can I download it?
http://download.osgeo.org/livedvd/
- Why is it useful?
Live DVD provides a number of open source geospatial tools, Desktop GIS,
Databases, Web services. Everything is compiled and ready to use. Also, there
are sample datasets and tutorials to get started.

4. - What's the Live user name and password?
user/user. See the passwords.txt file on the desktop for application specific
database user/passwords.
- What's the root password?
There isn't one. To run commands as root type `sudo <command>` in a
terminal. To become root type `sudo - su`. Enter the user's password when
prompted.

11. Around the core ossim library, the software distribution
includes a large number of command line utilities that
can be easily scripted for batch production systems and
higher level GUI applications – imagelinker, and
iview. Additionally, bindings have been generated for
other languages.
See "running imagelinker" (Massimo Di Stefano) at:

Ossim overview

12. Also included in the distribution are the osgPlanet and
osgPlanet_qt modules.
These modules build on top of OSSIM and
OpenSceneGraph to provide geospatially accurate 3D
visualization capabilities.

14. OssimPlanet and its applications

15. OssimPlanet is a 3D Geospatial viewer built on top of
OpenSceneGraph, Trolltech QT and OSSIM.
OssimPlanet extends geospatial viewing with access to
native geospatial formats, Elevation data sets, and OGC
Web Mapping Services (WMS) interfaces over the web.
osgPlanet is a C++ library and includes
ossimplanetviewer as a demonstration.
Ossimplanet and its applications

16. The current version of OssimPlanet supports:
● Staging of local geospatial files;
● Remote access of OGC WMS layers;
● Direct access to WorldWind protocol servers;
● Navigation to street addresses through the geocoding
menu item;
● osgEphemeris has also been recently incorporated
providing a skydome and current time/location
positioning of the sun, moon, and stars.
Ossimplanet and its applications

17. Ossimplanet and its applications
Supported Data Sets:
●OSSIM Geo-Spatial Formats
●GDAL Geo-Spatial Formats
●OGC WMS Interface
●WorldWind Server (a Web Mapping Service server)
●Pixia NUI format (proprietary file format)

18. Ossimplanet and its applications
Requirements:
OssimPlanet currently requires a 3 button mouse for navigation.
Event Action
Left mouse drag Rotates the globe
Right mouse drag Zoom in, zoom out
Arrow keys Start constant rotation
(accumulates with additional key
presses)
Return key Freezes all motions
Space bar Resets view to default position
W key Toggles between textured, wire
frame and point mode
L key Toggles directed light source
(currently disabled)
Ctrl+F Toggles full screen mode

19. Ossimplanet and its applications
Preferences:
Enable HUD
Heads Up Display includes the cross hairs at the center of the image and
the latitude, longitude, elevation, and height readout at the bottom left
hand corner of the display.
Enable elevation
Turns on or off elevation processing for topographic relief and
visualization in ossimPlanet. Elevation processing requires that elevation
data sets be staged through the Application Support directory for ossim.
DTED and SRTM file structures for elevation can be automatically
parsed and retrieved by the software.
Elevation multiplier
A pull down menu applies an elevation scaling factor. The higher the
number, the more exaggerated the topography.

20. Ossimplanet and its applications
Enable ephemeris
This checkbox enables the osgEphemeris library. If this option is
enabled, the system date and time as the well as the viewers location are
used to render a view of the heavens. The sun and the moon are
rendered in their relative positions against sky dome.
WMS
The OGC Web Mapping Services interface is supported in ossimPlanet.
The menu item will open a dialog box for getting WMS access to online
servers.

21. Ossimplanet and its applications
Open Session
A Session is an xml file that contains the state of the program including
data that has been loaded and the currrent view. The Open Session
command retrieves this file from disk, loads the data, and navigates to
the saved view.
Goto Lat Lon
Entering a Latitude, Longitude and optionally an altitude will navigate to
that position.

PlanetSasha:
PlanetSasha is a project started thanks to the OSGEO foundation and
Google-Summer-of-Code initiative.
http://web.me.com/epiesasha/PlanetSasha/Project.html
GUI description:
http://web.me.com/epiesasha/PlanetSasha/PlanetSasha.html
Developer : Massimo Di Stefano
Mentor : Mark Lucas
Aim of the project :
Development of a plug-in for the OssimPlanet application for interface
with other Open Source G.I.S software such as Grass and Qgis. This
allows to export the elevation and texture data from Grass/Qgis to
OssimPlanet. The result is to synchronize the grass/qgis maps canvas
extent with the Ossimplanet scene.

23. Ossimplanet and its applications
Application
Author: Massimo Di Stefano
Using a raster elevation map as base layer, display it in a 2D gui and use
the mouse movement to write a tour on the map. The tour has been
processed and the output is an elevation profile and the instruction to
execute the tour in ossimplanet.
