GeoLink™

GeoLink is a collection of MDL (MicroStation Development Language) programs, written by Australian Data Systems. These programs provide additional functions that are not a standard part of MicroStation or MicroStation GeoGraphics.

The following functions are provided by GeoLink:

Dissolve
Merges/copies the database records that are associated with the topological areas displayed with the option to dissolve/merge the graphical elements that make up those topological areas and create new features in the active design file. The areas processed can be in the active design file or in reference file(s). The operator selects the feature code to attach to the newly created graphics (shapes or boundaries and centroids).

Chklink
Validates and reports on the integrity of GeoGraphics data.

• For featurised graphical elements, check that the feature code still exists in the project database and that the type of element that it is attached to is appropriate for the feature definition.
• For graphic elements with database links, check that the entity number exists in the mscatalog table. If it is in the mscatalog, check that the record for the specific link still exists in the attribute table.
• Additional checks include: Maximum number of links per table per element; One element per link; Missing graphics; Missing features; One record per link; Missing map ID; Missing attribute table; and an option to remove orphan links.

Verlink
An aid to visually verify and optionally update individual database links that are attached to selected graphical elements in the active design file. The operator can choose the attribute table to check.

Bulk
Provides a bulk update facility for a database table. The records to be updated can be selected either by executing an SQL query, or by identifying graphical elements in a design file. The two methods can be combined to append records to an existing list. The database records are displayed in tabular form. Sorting and updating of records are controlled through this interface.

Remlink
Provides the ability to remove unwanted or redundant database links from selected graphical elements in the active design file.
