Generating an
Information Layer from a Table
Once a query process is
executed, by attributes, spatial or grouping, about an objects map, it is possible
to create a thematic or cadastral IL which represents the selected and/or
grouped objects.
To create a cadastral IL just define the Category, and all selected objects
will have their lines, polygons, and identifiers reproduced in the output
information layer.
To create a thematic IL
two distinct situations have to be considered by the user:
-
executing just an attributes and/or spatial query - in this case only the selected polygons, lines and points will
be copied to the thematic IL, and they will be associated to the
category first class;
-
executing a grouping, independently of
an attributes and/or spatial query - in this case a category and
associated classes can be automatically created using as a class name
the own group (or slice), or even using an existing thematic category,
in this last case it is required to define the most adequate
association.
Next the procedures for
each case described above will be presented.
Generating a cadastral IL after query executions:
-
activate in the "Control Panel" a cadastral category and an associated IL;
-
click on Query...
and, in the
"Generating and Selecting Collections" window, select a collection or all objects
(ALL option), and click on Apply;
-
select the desired objects using
the "
Attributes Query" and/or "Spatial Query" windows;
-
in the
Table module, click
on the Infolayer Generation button to open the "Infolayer
Generation" window;
-
click on Category... to select the category for the
Information Layer that will be created. The "
Categories List" window is presented. Select a cadastral category and click
on Apply in this window;
-
type in the Output Layer
a name for the IL;
-
click on Apply.
NOTE:
Verify, in the "Control Panel" that the just created IL will
be available for visualization.
Generating a thematic IL after performing queries:
-
activate in the "Control Panel" a cadastral category and an associated IL;
-
click on Query...
and in the
"Generating and Selecting a Collection" window select a collection, or all objects (ALL
option), and click on Apply;
-
select the desired objects using
the "
Attributes query" and/or "Spatial query" windows;
-
in the
Table module, click
on the Infolayer Generation button to open the "Information
Layer Generation" window;
-
click on Category... to select the category for the
Information Layer that will be created. The "
Category List" window is presented. Select a thematic categories and
click on Apply in this window;
-
type in the Output IL a
name for the IL;
-
click on Apply.
NOTE: Verify, in the "Control
Panel" that the just created IL will be available for visualization.
Generating a thematic IL after grouping executions:
-
activate in the "Control Panel" a cadastral category and an associated IL;
-
click on Query...
and in the
"Generating and Selecting Collections" window select a collection, or all objects
(ALL option), and click on Apply;
-
group the objects using the "Grouping Objects:<object_name>"
window;
-
in the
Table module, click
on the Infolayer Generation button to open the "Infolayer
Generation" window;
-
if you want to create a new thematic category:
-
click on Automatic Classes, type a name for the category and click on Create,
otherwise:
-
click on Category... to select the category for the
Information Layer that will be created. The " Category List"
window is presented. Select a thematic categories and click on Apply
in this window;
-
select a class in the Classes
list and then the groups, in the Association
list, which will be
associated to the selected class. By
default, the
association is done sequentially from classes to groups. The groups left
with no association are attached to a “None” class;
-
type in the Output Layer a
name for the IL;
-
click on Apply.
NOTE:
Verify, in the "Control Panel" that the just created IL will
be available for visualization. The created classes will have the same name
as the groups and the same color (visual), defined in the "Grouping
Objects:<object_name>"
window.
NOTE 1: The Class visual can be changed through the Visual...button.
