The Setup LRMs window contains two panes: the LRSs pane and the Columns pane. These panes are described in the following sections.

The LRSs Pane

The LRSs pane shows the base reference system (as denoted by a shadow check mark in the Basic LRS? column) along with a record for each alternate location reference method (LRM). The text entered in the Loc Ref Name column in the LRSs pane is what will appear in the drop-down list in the Location Reference field on the side of the browser window.
Each reference system is assigned a type in the LRS Type column, with the type being selected from a drop-down list. The list provides the following selections:

Use Location Across: This selection means that for this reference system the identification of a position laterally (for example, across the road) will be done using the two columns Lane Direction and Lane Number. (These two columns are pre-defined in the system, and appear in various windows throughout the system as indicated in the table below.)
Note: The Base LRM is always set to "Use Location Across," thus providing the capability of lateral positioning, which can then be employed (if desired) for a particular system implementation.
Ignore Location Across: This selection means that for this reference system the identification of a position laterally does not use the two pre-defined columns Lane Direction and Lane Number. See the table below for its affect in windows throughout the system.

Window Type/Situation	What Occurs When "Use Location Across" Is Selected for an Alternate LRM	What Occurs When "Ignore Location Across" Is Selected for an Alternate LRM
In the Alternate LRM Definition window.	The Lane Direction column is shown.	No lateral indication columns are shown.
In any location-referenced window when an alternate LRM is selected in the Location Reference field.	The Lane Direction and Lane Number columns are shown.	No lateral indication columns are shown.
In any location-referenced window when the base LRM is selected in the Location Reference field.	The Lane Direction and Lane Number columns are shown.	The Lane Direction and Lane Number columns are shown. (This is because the base LRM is always set to "Use Location Across.")

When you right-click an alternate LRMs in the upper pane, the system displays the following special command in a shortcut menu:

Make Window: This command displays a new window that shows the tree view of the menu items of the system. In the new window, click the parent menu item into which a menu item for the window that will show the cross-reference table between the Basic Reference System (BRS) and the selected alternate systems. After selecting the parent menu item, click OK to close the window. Then log off and log back on, and the menu item will be in the designated place, with the name of the menu item being what is entered in the Loc Ref Name column. Open the new window to see the cross-reference table. The BRS is shown on the left and the alternate system is on the right.

Columns Pane

Note: The values set in this pane for the base LRM should never be changed without first consulting AgileAssets.
The Columns pane shows the columns that define the reference system selected in the upper pane. The following columns appear in this pane:

Column ID: This column shows the internal column ID used in the system.
Column ID "To": This column shows the internal column ID used in the system. The contents of this field are not used if the Show "To" check box is clear.
Column Label: This columns shows the column heading label that appears for the column throughout the system.
Column Label "To": This column shows the column heading label that appears for this column throughout the system. The contents of this field are not used if the Show "To" check box is clear.
Hidden: When this check box is selected, the column will not be displayed.
Initial Value: If a value appears in this column, then the value will be automatically set to any record that is location-referenced when it is inserted into the system.
LRS Column Type: This column indicates whether the column is the "location measure" column. In defining an alternate LRMs, one and only one column must be set as the "location measure"; all other columns must be set as "location attribute".
Order: This column indicates the order (left to right) in which the columns are seen in data windows throughout the system.
Show "To"?: If the check box in this column is checked, then this LRM field will be shown twice in any location-referenced window when an alternate LRM is selected. It is shown once for the "from" point and then again for the "to" point. If clear, then the LRM field appears once and applies to both "from" and "to" points.
Note: This column must be checked for the column designated "location measure."
