Relational Links

Corresponding columns in different information sources can be used to create a link. For example, a parcel number can link parcel polygons to deed documents.

Address Links

Address data contained in document properties or in tables can be used to find map locations via address geocoding.

Dynamic Segmentation Links

Linear measurement data associated with documents or records can be used to mark locations (lines or points) on the map. Conversely, the documents or records can be found by pointing at the map.

Coordinate Links

Coordinates can be stored with documents or records and used to display points or boxes on the map. Users can then point at or select the graphic features to retrieve corresponding documents and/or records without the need to maintain additional features in the GIS. This may be especially useful for information that is very dynamic, ephemeral or not part of the GIS update workflow.

Geo-reference Links

Geo-registered files can be stored inside the document management system and retrieved for display on the GIS canvass. World files and pyramid files are managed with the parent documents and are automatically extracted when needed for display.

Content Links

Document management systems can search certain types of documents based on their content. Content links enable users to retrieve documents that contain text found in a database record or a GIS feature attribute.
