In the Control Panel window, the Information Layers and its different
representations are selected for visualization as well as for a desired
operation.
Every data manipulation
(edition, processing, crossings etc) is performed on the Information Layer that
is active in the Control Panel.
The Control Panel window is presented for the user along with the main Spring window, when a database Project is activated. It is
responsible for the functions of selecting data and controlling the visualization
displays.
The fields of the Control
Panel are enabled after a
project is activated. In this dialog box, the content of the project
(Information Layers) can be presented on the screen.
The option View in the menu bar of the Spring
module main window shows or hides the Control Panel through the options Active
Panel and Inactive Panel respectively, in the UNIX version, or
View - Control Panel () in the Windows
version.
The figure below represents
the Control Panel. In this figure,
the button Window Control allows one
to define the active window. The Available ILs field informs which Categories and Information Layers are available. Selected
ILs presents the ILs that were selected in the
Available ILs field. The letters (D, C, T, I and N) before the Category Names indicate
the type of category (for instance, D for DTM and C for Cadastral). The buttons
represent the draw, selection, search, vector edition, raster edition and help
operations.

Operating SPRING
To select an IL on which an
operation is about to be performed it is required to activate it or, depending
on the operation, it is necessary to draw it on the active display. To do so,
use the two lists of the Control Panel:
Available ILs and Selected
ILs.
When selecting an Information
Layer (IL), the options in the menu bar of the main window become
available to operate on that IL. Many times it is not necessary to view the datum, only the selection is enough, so that any application
is able to operate it.
Activating an IL
for operation:
NOTE: Observe that there will always be
an Active IL of the Active
Project, and its name will be shown
in the footnote area of the active drawing window, or as a dark stripe over the
name on the Information Layers List of the Control Panel. Depending on the model of the selected category, one of the options
of the main menu will be enabled. For instance, if the category is thematic,
the item Thematic will be enabled to
operate on the active IL.
To present one or more ILs in
one of the drawing areas, one must define which ILs will be presented for
visualization. In order to do it, it is necessary to activate the desired
display before selecting the data. The Main
window of the Spring
module is initially active. If no other window is activated, the data
selection will be in the Main one.
OBS: An activated IL is not necessarily
selected for visualization in one of the drawing areas. One should also select
its representations.
The selection of data for
visualization happens in the representations level. After selecting Category and Information Layer one must choose which representations of that IL
will be presented.
For each selected
representation, an equivalent letter is shown in parenthesis before the name of
the IL, indicating the selection. The representations vary depending on the IL
category, as follows:
THEMATIC
Points (P) -
show all 2D points; Lines (L) - show all lines defining a polygon or
not; Matrix (M) - vectors formatted as a matrix; Classes (C) -
presents points/lines/polygons that are associated to classes, with its
corresponding visual aspects; Text (T) - toponimy automatically
generated or edited.
NUMERIC
Samples (A)
- spot heights and imported contour lines or edited; Grid (G) -
rectangular grid; TIN (Ti) - triangular grid "Triangular Irregular
Network"; Contour Lines (I) - contour lines generated from a grid; Image
(Im) - gray level image of the grid; Text (T) - toponimy automatically
generated or edited.
IMAGE
M (M) -
monochromatic channel, R (R) - red channel, G (G) - green
channel, B (B) - blue channel; Text (T) - edited toponimy over the image;
Synthetic (S) - three band coding into a single image; Classified
(C) - image created by a classification process; Labeled (R) - lines
created by image segmentation.
NETWORK
Lines (L) -
show all lines; Objects (O) - show lines/nodes that are associated to
objects, with its corresponding visual aspects; Text (T) - toponimy
automatically generated or edited; Restrictions (R) - turn restrictions.
CADASTRAL
Points (P) -
show all 2D points; Lines (L) - show all lines defining a polygon or
not; Objects (O) - presents points/lines/polygons that are associated to
the objects, with the corresponding visual aspects; Text (T) - toponimy
automatically generated or edited.
OBS: All ILs can have associated texts presented. A text can be
edited/imported to any IL of any model, or automatically generated for ILs of
any model, except image.
The context menu presents a number of operations that are performed regarding in Active Infolayer or Category of Active Infolayer.
This menu is displayed when click with mouse right button on area of the tree of Category and Infolayers or on area of the List of Selected Infolayers.
Some of operations are:
Draw;
Vector Editing;
Raster Editing;
Query;
The Priority sets
the sequence for data visualization and it is associated to each Information
Layer. Click on
To visualize data one
should first Activate a window, select the set of representation desired
and then click on Draw in the activated window.
Visualizing
a project data:
NOTE: to deselect all the IL representation just do a double click
on the corresponding IL, or a double click on a category to deselect all
the ILs belonging to this category.
A thematic map can have its
entities (points, lines and polygons) associated to classes defined in
the Database, that is, each one with a different visualization aspects (color,
filling, pattern, etc.). If the user wants to present in the drawing window
only the polygons which are in a given class, he/she can use the
Data Selection, window, which allows the class selection to be
presented.
In the Numerical IL's case,
the sample representation can be of the following types: 3D, Lines 3D, Break
Line, or Master Line. With the Data Selection window it is possible to select
only some types for visualization.
NOTE: Once the classes to be presented are selected, from a certain IL,
these will be stored automatically, even if the Spring
module is finished. To restore the classes’ presentation in an IL, a new
selection has to be made.
NOTE: The line visualization of a thematic IL can be changed, because it
is independent of the filling defined for a polygon. The visualization of these
lines is defined through a dialog box
Information Layer.
Besides the Main Window, there are four
other windows for visualization, but n other windows can be created. The Auxiliary Window is specially reserved for some procedures, such as: data mosaicing
and images registration.
