PlanetScape Program
The main purpose of the program to make virtual excursions on different
bodies of the Solar System to study the landscape (more exactly planetscape)
of this bodies in 3D/Stereo and get information about them.
PlanetScape Navigator
The Navigator makes posssible to choose a planet, to navigate on
the planet or moon choosed, to set options, to save the Navigator
image and to start the image processor (only for Mars for the time being).
The navigator window contains a menubar, two toolbars, and image splitpane
an under the image splitpane a message line.
The right side of the splitpane is an image panel for the globes of
the planet/moon and the left side has a tree for navigation by features
of the planet. The tooltip of the tree elements has some information about
the given feature of the planet..
Choosing a feature will center the globe around this feature in the
low and middle resolution mode and put a cross on the feature in the high
resolution mode. The high resolution mode the latitude and longitude data
will be put in the boxes concernd.

Choosing a Planet or a Moon
One can choose a planet from the menu "Planets". Only Mars has the
data files to fully use the program. For other planets (Moon, Venus,
Callisto, Europa, Ganymede) the only possibility to navigate and save the
image.
The most unfortunate thing, that there is no topographical data measured
by a laser altimeter for the Moon .
Navigation
The PlanetScape Navigator gives the possibility to chose a place
of the investigated planet.
The different possibilities as follows:
Navigate by tree: to open a folder double click, to choose a tree element
click!
Navigate with the Go East, West, North and South
buttons: the step regulated in degrees by the slider
Give the exact latitude and longitude and press the refreh button
Click on either sphere of Mars and the clicked point will be the
centre of the main Mars sphere. (The spheres are
generated from the file *.jpg under the .../globus/ directory of
the specified planet. They can be configured by the planet's property
file. Use them depending on the speed of your computer and real estate
your display.)
Saving the Image
The image can be saved as a .png file with the use of "Save" menu item
under the "File" menu.
Choosing the option for the image processor, resolution and the globes
It is important to say, that the user can add its image the ../globus directory
and edit the planet's property file to change for new images. The added
images shoulde be jpg files
The option chooses the colors for surface colouring: So every surface
point will have the color code for that point or the surface color . The
actual file for the surface will be generated in the image processig.
One globe with its two side or two different globe with the same side and
Resolutions: The high resolution is always in one globe mode.
Activation of the Image Processor
The "Load" button loads the images around the centre choosed in the navigation
process. If the processor is not active, it will be activated.
PlanetScape Image Processor
The processor window contains a toobar, two image plate and a message line.
The toolbar has the following actions:
Save button: it saves the two images together in .png format
Enlarge button makes a twofold enlargement on both images
Export button writes the information about the choosed territory
into the file planet.dta . The Surface Viewer program will use this
file to generate different view about the choosed territory
Elevation Plot button: Choose a line on the topographical
image with the second mouse button (dragging it and click the icon.
Refresh button: It refreshes the images with coordinates from latitude,
longitude text field. (It is meant for moon observers: choosing a named
place on the moon one can refresh the images around this place)
Comment line: The user can add a line of comment to the surface
picture. This line and the information about the choosed territory (which
is visible in the title) wil lbe added to the planet.dta file.
Actions on the topographical images:
Moving the mouse pointer in the topographical image will write the elevation
information of the place into the message line.
dragging with the left button pressed will chose a territory to export.
dragging with the middle button pressed will give a yellow line for elevation
plotting
Clicking with the right mouse button into the left (topological) image,
a popup menu comes up.

Zooming will enlarge twofold the images: it uses a simple linear interpolation
so for a better surface you can use the blurring. However the blurring
will change the value of the original points too. We need a better interpolation
for the enlargement. The "Parameters" menu changes the threshold
parameter which can be between 10 and 230. In the beginning the parameter
10 and clicking on the menu element will add 10 to the original value.
After 230 it will be 10 again. It is a very temporary solution. The "Save"
menu element will save the topological image in png format.
Do not forget to place the sgt_v2.jar file into the jre/lib/ext
directory from the PlanetScape/lib directory
Under the elevation plot there are three button for
the regeneration of the original plot (One can choose an area on
the plot with the left mouse button to enlarge)
edit the attributes of the plot and
print the plot.
PlanetScape Surface Viewer
The "Surface Viewer " window contains a horizontal and vertical toolbar
and an image plane.
The vertical toolbar has the following buttons:
Viewpoint up
Viewpoint down
Increase viewing distance
Decrease viewing distance
The horizontal tolbar has the following:
Refresh button
Viewpoint left
Viewpoint right
Slider for tuning the steps of viewpoint's change in horizontal
Zoom in (2x enlargement)
Zoom out
Open a .dta file to make the image (to keep the planet.dta rename it)
Save the image in a .png file
Stereo checkbox: if it is checked you can see the image in stereo with
3D glasses
Shading checkbox: if it is checked, the image will be generated with shades
