CampControl is an Internet-based system for managing the flow of information, supplies, samples and personnel between main centres and mineral exploration camps.

CampControl greatly improves management efficiency, reduces exploration costs, and improves staff motivation.

CampControl can be deployed anywhere in the world.

Starting in British Columbia and the North West Territories in 2007, CampControl now has users from Nunavut to Mongolia.

 TLE is a powerful tool for creating, reviewing and editing many types of hierarchical data and information, in particular, classifications.

Many geological classifications are available for download from the TLE site - such as the BGS Rock Classification System, AGSO's Geological Time-Scale, and others.

TLE is also able to import classifications existing is the SKOS format.

TLE uses the power of Drag-And-Drop editing in an easy-to-use graphical environment, and provides many other functions necessary for the collaborative development of formal science languages.


MineMatch is a system for describing and comparing mineral deposits, deposit models, and exploration prospects,  -  as well as for communicating these descriptions effectively between geologists and other interested persons.

MineMatch Online is available for use free-of-charge.  It is a web service which can be used anywhere in the world to produce invaluable appendices for 43-101-compliant technical reports in PDF format - without downloading any software.

To find out more about the history of  MineMatch, please visit the original MineMatch website.

HazardMatch is an internet-based computer system developed by Georeference Online Ltd, with the assistance of the Geological Survey of Canada, for identifying and mapping areas that are susceptible to natural hazards.  The application uses the descriptions of geotechnical experts, modern computer reasoning capabilities, and existing GIS data sets to identify these areas.

HazardMatch is a highly-accessible decision-support tool intended for use by government and community planners, insurance companies and scientific researchers.   It seeks to reduce the cost of producing hazard maps, at the same time as improving their auditability and making them easier to understand by non-experts in geotechnical engineering.  HazardMatch was originally developed using the desktop LegendBurster system (see below), although it is now a stand-alone Internet application.

For more information about HazardMatch, please contact Georeference Online Ltd.

LegendBurster was the first commercial system in the world to provide Semantic Net functionality in a GIS environment.  It is  an essential tool for representing ontologically-structured data on maps, and for easy, effective querying of such data. 

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

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.
