![]() Controlling Objects
Visualization
The Visualizing Objects interface is
composed of a toolbar and a list of objects
(see figure below) where all categories that belong to the Information Layer
are shown. The control is done using the two check boxes on the left of each
category name (check the rectangle to see the category on the map and the
triangle to see the legend).
NOTE:
The map presentation is always done on the current screen where the query was
performed. However, it is possible to enable and show other displays,
performing new queries, and then comparing the results in more than one
window. Check below the figure with a cadastral map that contains blocks,
roads, labels etc. Showing Legends and
presentation order
Each objects category
might have a different look and the Visualizing
Objects interface has buttons that allow or not the
visualization of legend in each category. It is also possible to define the
order of objects exhibition when drawing the map. Notice that depending on
the order chosen, some objects might be covered by others.
Observe the presentation
order on the figure above:
Selecting the objects
category
When the IL selected for
query presents more than one objects category, you must choose one of them
for applying the operations available at this interface. The selected
category is always highlighted on the list. Notice on the figure above that
the object category "Malls"
was selected.
On the dialog box
"Objects Visualization", double click on one of the
categories of the list and the rectangle highlighting it is presented. This dialog box also
presents a toolbar which has the following options for analyzing the object
category chosen by pressing one of the following buttons: NOTE: In addition, an item named Undo Query is available. When one selects this
option, all the applied queries (spatial and by attributes) are removed.
