Resource Assessment Using a Geographical I[ivfohm, Ltion System: a Pilot Study in the Smithers A.rea*

and this has been a common practice within the British Columbia Geological Survey Branch for a number of years (MacIntyre, 1991). Geological data are commonly stored in CAD-based files that record points. lines and polygons that describe geological features. Additional infolmation that includes structural measurements and other descriptive features of field data are commonly stored in database management systems that have assnciated geographical coordinates. An integrated mapping program that has tied both the geological vector-.based data with the attributes that describe the features at specific geographic locations has been implemented by the Ontario Geological Survey (Brodaric and Fyon, 19x9). Such systems are a step towards an integrated approach to data capture and management in ways that were not previously possible.
