Control Panel

It is through the "Control Panel" window that the Information Layers and their different representations are selected either for visualization or for the desired operation.

All the data manipulation (editing, processing, crossing, etc. ...) is performed over the Information Layer which is active in the "Control Panel".

The "Control Panel" window is presented for the user together with the Spring main window when the Database Project is activated, and it is responsible for the data selection function and the visualization windows control.

The "Control Panel" fields are enabled only after a project activation. It is through this dialog box that all the project contents (Information Layers) can be presented in the computer window.

The View option in the menu bar of the main window in the spring module allows to show or hide the "Control Panel" through the View - Control Panel options.

How to select data for an operation

To select an IL over which an operation will be performed it is required, first, to activate it, or even, depending on the operation it is required to display it in the active window. So, use both lists Categories and Information Layer in the "Control Panel".

  • Categories - only the categories in the active Database which have at least an Information Layer in the active project are presented. According to the category, the IL's and their available representations are presented. The parentheses "( )" at the category's side are filled with (V) when some IL of that category is selected.
  • Information Layers - are presented according to the selected category. The field below shows the available representations for the selected Information Layer.

When selecting an Information Layer (IL) it is enable the options in the menu bar in the main window to operate over that IL. Many times it is not required the data visualization, only the selection is enough so that any application works over it.


Activating an IL for operation:

  • activate a Database ( atalho_bancod.gif - 1054 Bytes) and a Project ( atalho_projeto.gif - 1036 Bytes). Automatically the "Control Panel" is presented;
  • select View – Control Panel or View - Control Panel (Windows) atalho_painel.gif - 967 Bytesin the main menu if, for any reason, the "Control Panel" is closed;
  • select a Category in the list;
  • select a corresponding Information Layer.

NOTE: Notice that there will always be an active IL from the active Project, and its name will be displayed in the footnote area in the active drawing window at the moment, or as a dark highlighted line over the name in the Information Layer list in the "Control Panel". Notice that according to the selected category model it will be enabled one of the options in the main menu. For instance, if the category selected is the thematic, the option Thematic will be enable to work over the active IL.

How to visualize an IL

To display one or more IL in one of the five drawing areas, one has to define which ILs will be presented for visualization. In order to do this, it is required to activate the desired window before selecting the data. The Window 1 corresponds to the main window of the "Spring" module, which is initially active. If no other window is activated, the data selection will be in Window 1.

NOTE: An active IL does not mean that it will be selected to present it in one of the drawing areas. It is required also to select its representations.

The data selection for visualization happens at the representation level. After selecting the Category and Information Layer one should select the IL's representation that will be displayed.

For each selected representation, an equivalent letter is introduced between parenthesis before the IL's name, indicating the selection. The representations change according to the Information Layer category, as follows:

THEMATIC

Points (P) - it presents all the 2D points; Lines (L) - it presents all lines, defining or not a polygon; Matrix (M) - vectors are represented using a matrix format; Classes (C) - it presents points/lines/polygons associated to classes and their respective visualizations; Text (T) - toponymy automatic generated or edited.

NUMERICAL

Samples (A) - spot heights and imported or edited contour lines; Grids (G) - rectangular grid; TIN (Ti) - triangular grid "Triangular Irregular Network"; Contour lines (I) - contour lines generated from the grid; Image (Im) - grid gray level image; Text (T) - toponymy automatic generated or edited.

IMAGE

M (M) - monochromatic channel , R (R) - red band, G (G) - green band, B (B) - blue band; Text (T) - toponymy edited over an image; Synthetic (S) - it codes three bands into a single image band; Labeled (C) - image created by labeling processes; Segmented (R) - lines created by an image segmentation process.

NETWORK

Lines (L) - it presents all lines; Objects (O) - it presents lines/nodes associated to an object and their respective visualization; Text (T) - toponymy automatic generated or edited.

CADASTRAL

Points (P) - presents all the 2D points; Lines (L) - it presents all lines, defining or not a polygon; Objects (O) - it presents lines/nodes associated to an object and their respective visualization; Text (T) - toponymy automatic generated or edited.


NOTE: All the ILs can have a text presentation associated. A text can be edited/imported for any IL of any model, or generated automatically for ILs of any model, but image.

 

Priority

The Priority sets the visualization sequence for data visualization and it is associated to each Information Layer. The higher the visualization priority the lower the presentation order, so, an IL with priority 100 will be presented before an IL with priority 110.

IMPORTANT: Click on CR after entering the priority value for each IL.

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:

  • activate the Database ( atalho_bancod.gif - 1054 Bytes) and the Project ( atalho_projeto.gif - 1036 Bytes) desired;
  • select View – Control Panel or View - Control Panel (Windows) atalho_painel.gif - 967 Bytesin the main menu if, for any reason, the "Control Panel" is closed;
  • select a Category;
  • select an Information Layer;
  • activate in the Windows Control, of the "Control Panel", the desired window;
  • select the set of data for visualization, in the "Control Panel", selecting the desired Representation and define the Priority for each IL;
  • click on Draw or atalho_desenhar.gif - 941 Bytesin the active window.


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.

 

Thematic Classes Selection or Samples

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".

How to control the SPRING windows

Besides the Window 1 represented by the main window of the spring module, there are four other windows for visualization, numbered 2, 3, 4 and 5. The window 5 is specially reserved for some procedures, such as: data mosaicing and images registration. The opened windows definition, active and linked in the working area is performed through the present options in the Windows Control of the "Control Panel".

  • Activate a window is important for the data selection definition for visualization and for operation results presentation which are performed in the window, as contour lines generation for instance. Activate a window is an exclusive option, that is, only a window can be active at each time. When activating another window, the previous will be automatically deactivated. Activating a window and an IL are independents, because, when activating a window where previously an IL was selected for this window, it does not mean that this IL will be active just by activating the window. When the "Spring" module is initiated the window 1 (main window) will be by default the active window.
  • View - it controls the windows presence in the working area. All the five windows can be presented at the same time, because, these are non exclusive options. When showing any other window, besides window 1, this will become the active window. To close a window in the working area, just remove the window selection or click on the window's Close button (or Alt+F4). The system store the ILs which are selected in each of the five windows. Even if the active window is closed or changed, the data will be kept selected.
  • Link - it controls the presentation in the Window 1, such that a rectangle in the working area presents the selected data in another window. This rectangle is movable and it is manipulated in the same way that the zoom resource. See more details at how to link a drawing window.

NOTE: The system stores the ILs which are selected in each of the five windows. Even if the active window is changed or closed, the data will be kept selected.


Zooming the Drawing Area

Once there is one or more ILs drawn in some of the five windows, it is possible to enlarge, using another window, what is being seen. In the "Control Panel" use the "Zoom" button to increase 2, 4 or 8 times the data in the drawing area. Move the cursor over one of the windows and the cursor position will also be increased, by the same factor selected (the figure below shows the cursor position increased 4 times).

NOTE: This zooming resource is really useful when one wants to locate with a higher precision the control points in an image registration process.
