Cursor Display
There are four different cursor styles: Hand, Pointer, I, and Cross. The cursor changes appearance
depending on its screen location and functionality. These cursors’ functions are initiated by clicking on the
left mouse button.
3.1. Hand
The cursor appears as a hand when it is over an active link on the web page or tool bars. This is an
indication that some action will occur if the left mouse button is clicked.
3.2. Pointer
The cursor appears as a pointer when it is over some form fields or any part of the map when no
other command is active (e.g.: zoom or monument select commands). Users can make form
selections from drop down lists by clicking the left mouse button when the pointer cursor appears.
Clicking the left mouse button over active map features initiates an action. When the left mouse
button is clicked over a survey monument when the cursor is a pointer, the Point Reporter page opens
and that monument’s data is displayed.
3.3. Text Bar
The cursor appears as an “I” when it is over a form field that will accept textural key-ins. Clicking the
left mouse button opens the field for data entry. Users can delete existing information or enter new
information from the keyboard at the point where the text cursor was placed.
3.4. Cross
The pointer appears as a cross when the select and zoom commands are used to identify an area of
the map. Zoom Window and the monument selection commands are the primary commands that use
this cursor.

Map Legend Display Control
The Map Legend controls feature display in the map. The Map Legend lists all available features for the
current map window (depending on the zoom level). Users click on the check marks to turn the features
on or off in the map. The legend automatically updates as the zoom level changes and features are
turned on or off by the web application (see Display Thresholds – Section 4.3).
4.1. Default Legend Setting
The legend displays the features in Figure 4.1 when the statewide map is displayed. The legend will
change depending on the features that are available for display in the map area and at the specified
Figure 4.1 - Legend Settings
4.2. Legend of a Zoomed In Area
The legend automatically updates when the map window changes, and additional features are turned
off or on. Figure 4.2 shows an area of Carson City with additional features including survey
monuments. In the example, the color filled City Limits feature is unchecked and is not displayed on
the map.

4.3. Display Thresholds
The term Display Threshold describes the automatic process that determines which features will be
displayed as the map view changes. To keep the LoIS map from being too cluttered and difficult to
read, LoIS Web automatically checks the map extents and updates the map and legend with the
features appropriate for that view. Users are not able to change the display threshold settings.
In addition to the Display Thresholds, the legend will not contain entries for features that do not exist
on the map extent. For example, if no city limit boundaries exist in the map, then the legend entry
for City Limits will be removed.
