Segment Map Properties

Segment Map tab:

Object type and name:

Segment Map "Segment map name": the segment map is an editable source map.

Dependent Segment Map "Segment map name": the segment map is the result of an operation.

When you click this flat button, the segment map will be (re)opened.

Coordinate system:

The name and the description of the coordinate system used by this segment map are listed.

Boundaries of map:

The coordinate boundaries of this map are listed as (MinX, MinY) and (MaxX, MaxY).

Domain:

The name of the domain that is used by this segment map is listed. Also the description of the domain is listed.

Value range:

In case this map uses a value domain, the minimum and maximum values that can be stored by this map are listed. This is also called the value range of the map.

Precision:

In case this map uses a value domain, the precision of the values that can be stored by this map is listed.

Attribute table:

In case this map uses a class or ID domain, and the map or the domain has an attribute table, then the name of the attribute table is shown.

Select this check box to link an attribute table to this segment map, or select this check box to create a new attribute table for this segment map (click the create button).

Definition:

For dependent maps: the expression by which the object was created is listed, i.e. the object definition.

Number of segments:

The number of segments as counted by the system in this segment map; this includes segments that are marked for deletion (undefined value).

General tab:

Object type and name:

Segment Map "Segment map name": the segment map is an editable source map.

Dependent Segment Map "Segment map name": the segment map is the result of an operation.

When you click this flat button, the segment map will be (re)opened.

Location:

The path and directory where this object is stored.

Object date and time:

Date and time when this segment map was last changed.

Object size:

Total size of the segment map on disk in bytes (.MPS and .MPS#).

Read only:

Select this check box to make the segment map read only. Clear this check box to make the segment map changeable.

Description:

Description of the object; freely editable. The description of a map appears in the title bar of a map window when the map is displayed. Furthermore, the description is visible on the status bar of the Main window when moving the mouse pointer over the map in a Catalog.

Dependency tab (for dependent maps):

Object type and name:

Dependent Segment Map "Segment map name": the segment map is the result of an operation. When you click this flat button, the segment map will be (re)opened.

Definition:

The expression by which the object was created is listed, i.e. the object definition.

Up-to-date or not:

Lists whether this segment map is up-to-date or not. If not, the name of the object which was changed last is shown including that object's date and time.

Depends on:

In a tree view, the names of the objects are listed on which this segment map depends.

Calculate:

When only the object definition file of this segment map (.MPS) exists:

• click this button to (re)calculate the data file (.MPS#) of this segment map by (re)executing the definition of this map.

Make Up-to-Date:

When the segment map is not up-to-date anymore,

i.e. when one or more objects on which this segment map depends have been changed, and when both the object definition file (.MPS) and the data file (.MPS#) of segment point map exist:

• click this button to check all objects on which this segment map depends, see if these are up-to-date, if not, check all objects below, etc.,
• recalculate all changed objects on which this segment map depends, and finally recalculate the data file of this segment map using all new changed objects.

Release Disk Space:

When both the object definition file (.MPS) and a calculated data file (.MPS#) exist:

• click this button to delete the data file of this segment map.

The expression by which this dependent segment map was created remains stored in the object definition file, so this segment map can always be recalculated.

Break Dependency Link:

Whether this segment map is Up-to-Date or not:

• click this button to break the dependency link between this segment map and the objects on which it depends. This segment map will become an editable source object.

Do not break the dependency link if you wish to be able to update this segment map in a later stage on the basis of changed input objects.

Used By tab:

Object type and name:

Segment Map "Segment map name": the segment map is an editable source map.

Dependent Segment Map "Segment map name": the segment map is the result of an operation.

When you click this flat button, the segment map will be (re)opened.

Used By:

In a tree view, it is listed by which other objects this segment map is used.
