Symbology for Live View

*Live View is available in all license levels of LP360.

About the Symbology for Live View

Symbology for Live View is the color and size of a point. Symbology can be uniquely assigned for Classification and Returns on a view by view basis. That is, the Ground class (class 2) could have a different color and/or size in the Map View and the 3D View.

Symbology cannot be separately assigned for the Points and TIN channel. That is, a particular class or return will show with the same color regardless of the channel through which that point is rendered. 

Overview of Symbology for Live View

Double Click Class/Return Button

Double click the Class Row in grid or select the Settings button. This will invoke the Symbology dialog. 

Note that the Symbol drop-down serves no function – points are always displayed using the same symbol (a square) in LP360 (this selector will eventually be removed from the dialog). Here, you can set the size and color of the point. Note that the class or return for which symbology is being modified is displayed in the title bar of the Symbology dialog (in the example below, Return 2 of 2 is being modified).

Double Click Return Button

Right Clicking Return button will invoke the dialog of Figure 2 or Figure 3, respectively. From this dialog, you can choose to operate on the selected return, all On Returns or all Off Returns. Below is the right-click dialog from the Ground class button

Below is the Right Click dialog from the Return 2 of 2 button

Navigating one of these options will allow you to select the symbology option. This will invoke the Symbology dialog (Figure 1).

Color Grouping

Note that using the right click function for multiple Classes/Returns can be very handy for color grouping. For example, to color all last returns red, select Last Returns in the drop down list on the Returns tab. Now right click on one of the return buttons and select All On Returns. Navigate to Symbology and set the color to Yellow. Now all last returns will display in Yellow.

Point Size

Point size can be set on an attribute (elevation, classification, intensity, Point Source ID, etc.) by attribute basis or globally for all points. Point size is set on a class/return by class/return basis using the Symbology dialog. This is referred to as the Legend setting.

Point size is adjusted for a view using the Point Size selector in Live View. The first option in the drop down list sets the size to use the settings in the Legend. The numeric options override the legend and set all points, regardless of the legend, to the selected size.

L refers to the Size listed for the display legend atrribute or override with a selected point size or override with a selected point size.

The example above the "L" refers to point size but could also be point source ID).

Note that even though point size is technically a Symbology attribute, the Size override function (that is, selecting a numeric value in the drop down) function is applied to the same views selected for Filter application (lower left checkboxes in the main Live View dialog). This prevents colors from being reassigned in the other views when all you wanted to do was a temporary size change. 

L referes to the Size listed for the display legend attribute.

Symbology is Filter Independent

Note that symbology settings are independent of the filters. Thus if you recolor the ground class for the Map View while working on a filter that you might have labeled “Stockpile”, that same symbology will apply to the ground class in the Map View for all other filters.

Setting the Syncronized Views

LP360 allows each view to have independent symbology. That is, you might set Ground to be orange in the Map View with a point size of 1 but red in the 3D View with a point size of 3. 

Symbology is applied to the view or views that you have checked in the lower left of the Live View dialog. This setting defaults to the View from which you most recently pressed the Live View activation button. If you want the current symbology to syncronize with  other views, simply check those in the Apply Symbology to View section of the Live View dialog.

Display Updates provides a Live and Manual option. If you choose the Manual option use the Refresh button to apply the change to  syncronize the views.

Scan

Scan the points in the LAS files on the active LAS Layer to pupulated point counts in Live View. Changes sampled point counts (shown in red) to real point counds (show in black). Also used to populate the list of point souce ids for the data o nthe active LAS Layer. Scan is similar to the scan funtion in the LAS File Analyst where a complete scan of point attributes and header information can be viewed.
