Current data on Canada’s forest resources are incomplete, inaccurate and insufficiently location-specific. To eliminate these deficiencies, the Forest Resource Data Program of the Forest Management Institute was assigned the task of developing a new data system. This report describes the procedures, problems, cost and manpower requirements, and results of the pilot study. The pilot area of about 250 000 sq km was located in central Saskatchewan. Provincial and federal forest resource data were summarized using the townships as summary units, and reclassified and merged using a new area-based classification system. A mini-computer was used for this purpose, and also to extract data from the resulting database. Attempts to obtain data from other sources, and to use a database management system to extract data, were unsucessful due to a lack of time and resources. Tabular data summaries of area and volume were extracted from the database using a number of different classifiers and classes. Also, colour maps were produced using an automated mapping system, showing attributes of individual townships. The study took one year to complete, required 2.6 man-years of labour, and cost $70,000. It is estimated that, if done operationally, these figures would be cut in half. The pilot study successfully demonstrated the practical application of the Canadian Forest Resource Data System: data from different sources can be combined and summary tables and location-specific maps of the data can be produced. The experience and information gained are necessary and sufficient for a nation-wide implementation.
