Integrating Knowledge Representation
into GIS
  ESRI UC, San Diego, Aug 2004

LegendBurster is the first commercial system in the world to provide Semantic Net functionality in a modern GIS environment. 

Semantic Nets provide a more flexible representation of point, line and polygon attributes than flat database tables, and, depending on the data, often permit significantly more powerful querying capabilities than standard SQL. 

LegendBurster Semantic Nets are ideally suited for the management of:

  • Hierarchically structured information, such as scientific classification systems
    < View Example >

  • Open-ended lists of attribute values
    < View Example>

  • Features which are explicitly negated or declared to be absent <Explanation>

LegendBurster query results include scored partial matches in addition to exact query matches  -  often a critical advantage during exploratory data analysis  <Example>.  Weightings for the partial matches take into account the three data management issues mentioned above in a fully-auditable manner which includes an interactive explanation facility <Example>. 

Results-weighting algorithms are explained in a paper downloadble from this web site. < Read more .... >

LegendBurster is built around ESRI’s MapObjects technology.  It is available in versions ranging from a free Reader, which can view LegendBurster ontologies, semantic net descriptions and query results, to the most powerful "ArcGIS 8.x Add-In" edition, which can edit semantic nets and line-work.

LegendBurster includes a powerful Ontology Editor which allows for the development and exchange of standardized vocabularies in any discipline  -  an essential requirement for interoperable datasets.

Although still used in-house for consulting assignements, LegendBurster™ has been withdrawn from the market while its reasoning engine is being upgraded to conform to the emerging standards of the Semantic Web, and while it is being re-designd to operate independently of any single proprietary GIS system.

Until ESRI's upgrade of ArcGIS to Version 9, which was incompatible with Add-Ins developed for 8.3, LegendBurster used to be sold at the following prices:


Price* (Canada$/US$ )

Standalone C$600 ~US$400
ArcGIS 8x Add-In


~ US$800
