VISUALIZING CADASTRAL
DATA
Up to this moment we have
visualized image data, thematic data, and digital data in the form of maps
and images in the canvas. These data characterize what we call geographic
fields.
Next we will visualize
cadastral data. Some geographical entities, in order to be characterized,
they need to be: individualized, qualified by a set of features, and
represented as maps, which characterize its form and localization, for
instance a street, a plaza, etc. These entities characterize what we called geographical objects.
Because they have
attributes, it is not enough to show them as maps in the canvas, it is
necessary to also visualize a table showing these attributes. Using the SPRING System tools it is possible to point an object in the table and visualize
the object representation or to point the object representation and see its
classification in the table.
Visualizing
Geographical Objects:
-
click in View in the main
menu and enable the Control Panel, or the button
in the toolbar, in the case the Control Panel is not visible.
-
select the Cadastro_Urbano category and the
IL Mapa_quadras. Select the Lines and Objects
buttons.

-
Click the Query... button
in the panel.
-
the "
Generating and Selecting Collections"
window will be presented. This window allow to select an object subset
in a cadastral map in order to be analyzed. This option is useful when
the object table is very large, and consulting is too slow. In this case
it is not required because the attributes table has a little over a
hundred objects. Thus
click in Apply in this window;
-
after a couple of seconds a table and a
Visualizing Objects Display
will show up.
-
select Blocks in the
Display. Click on the drawing button in the toolbar. The filling
blocks get a color. The blocks not filled were not identified.
-
Iconize the Visualization
Objects Display.
-
Point an object in the table,
clicking over any line in the first column.
-
Notice in the blocks map, active in the Main Display, the block
corresponding to that line in the table is being filled with another
color.
-
clicking inside one of the squares
that build up the blocks drawing, all its attributes are highlighted in
the table.
-
to deactivate the selected lines,
click using the mouse right button over any line in the first column and select the option
Remove - Marks - All
-
close the Visualization Objects Display.
