Point Property Attributes

This option allows the user to change the properties of one or more points. If multiple points are selected, the changes are applied to all the points. This makes it easy to change the height, code or extra attributes of a whole set of points at once.

Point Number
The point number can be any point number in the range of points allowed for the job. The maximum point number is set in the File\Job Settings option. This option does not allow the point number to be changed, use the Renumber option. The Show check box controls whether the point number is displayed on the screen.

Easting and Northing
Every point must have an Easting (X) value, it is stored to more than 6 decimal places but only displayed to three decimal places. You can see the Easting (X) and Northing (Y) value for the mouse displayed in the bottom left of the screen as you move the mouse.

Interp Ht
This button computes a height value for the point(s) from the triangles if the point does not already have a height associated with it.

The height (Z) value for the point is optional. If a point has no height value, this field will be blank. Computed points like lot corners will generally not have a height value. The height value is stored to more than 6 decimal places but only displayed to three decimal places. The Show check box control whether the point height (RL) is displayed on the screen.

The point code is a text string which is associated with the point. Generally this will be entered during the field survey to indicate what type of point feature is being measured. e.g. a code ‘FC01’ may be used to tag a point on a fence line (fence line 1). The code can consist of alpha and numeric characters, it can be of any length, but generally is less than 10 characters long. The Show check box control whether the point code is displayed on the screen.

Select the layer on which the point(s) reside. See Layers for more details on how layers work. When editing point properties for multiple points, if they are on different layers the layer will be shown as * Various, if that is not changed, the points are left on their current layers. If a new layer is selected, all the selected points are moved onto the new layer.

Each point may have a remark attached. this is generally taken from the field data recorder and contains field notes about the point.

A point can have a name. e.g. for a state survey mark, the control point name can be entered.

Extra Attributes
The first five Extra Attributes will bedisplayed for the selected point(s).
If multiple points are selected with an attribute and you edit the attribute, all the selected points will be updated.

If you change any attributes, only those points with the changed attribute name will be updated.
If point 1 has attributes
Point 2 has attributes
If you change the CCCC attribute to zzz, only point 2 will be updated.
If you change the AAAA attribute to xxx, both points will be updated.

Displaying Points
To display a point (enter points mode) and double click on the point, or click once on the point and press the Properties button. To select multiple points, hold down the Shift or Ctrl keys and click on more points. When the properties button is pressed the points properties will be displayed.

Display of Multiple Points
When multiple points are selected and displayed, the value will be marked as ‘* Various’ if the points have different values. If say two points are selected, and a height of ‘* various’ is displayed, that means that the points have different heights. If the height displayed is say ‘125.000’, that means BOTH points have the same height.

If points have different values, you can select a single value to be applied to all selected points. This is an easy way to apply a single value to a range of points.
