The Tools menu
Distance, Cumulative, Surface
These functions compute a distance between two points,
cumulative distances between several points and surfaces
(end with double-click).
The pop-up menu of each function (right click) is
respectively the same as the one to create a line, a broken
line or a surface.
The result of the measurement is displayed in a label at the
bottom of the graphic window. Click the box on the left to
keep the label displayed.
Note:
When the «Snap» option is set to TRUE in the Preferences, it is possible to lorg on the layers’ graphic elements.
GrInfo
Once this function called for, a new tab appears and presents a table.
This function gives geometric information on the selected map objects
(only if the «Info.Gr» option is set to TRUE in the Preferences).
Objects are selected with the Select command toolbar.
Note:
The «Partial» option in the Preferences allows selecting objects either
partly (TRUE) or completely (FALSE) in the area. This concerns the
modes of selection by area.
Click the «Add» option in the pop-up menu of the selection and the
information on selected objects is added to the table. Also, the sum of
distances, perimeters and areas is displayed in the bottom of the
table.
Index Img Layer
This menu gives access to an extremely powerful function; that is the possibility to compute and create an image layer
based on a group of georeferenced images. It goes without saying that these georeferenced images may not overlap
and should be adjacent, just like in a checkerboard.
To do so, select one sole image among the ones in the directory. Note that during that operation, the system has
indexed images and has created an XML file called «Layer.XML» in the directory in which the images are stored.
Note:
This file is created with the user exits MobileSTAR.
Once the image layer computed, it is displayed in an overview. First-time display may take some time. We
recommend you afterwards to define the visibility scales of your image layer in the pop-up menu that goes with the
name of your image layer in the theme manager.
