<p>The Yukon Geological Survey (YGS) has compiled over 195 surficial geology maps into a standardized GIS format, providing approximately 80% coverage of the territory. The maps range in scales from 1:250,000 to 1:10,000 with spatial overlap between scales. The original maps were produced by various agencies, including the Geological Survey of Canada, YGS, Yukon Government, universities, and the City of Whitehorse.</p>
<p> All original feature descriptions have been preserved and also converted to standardized values using the Yukon terrain classification system. The compilation includes 4 GIS datasets and supporting documents available for download via <a href="https://data.geology.gov.yk.ca/Compilation/33" rel="nofollow ugc"> YGS integrated data system</a> (YGSIDS) or GeoYukon. A .lyr file is <a href="https://data.geology.gov.yk.ca/Compilation/33" rel="nofollow ugc"> provided</a> to symbolize feature classes and differentiate overlapping maps at different scales. Additionally, there is a surficial geology map index.</p>
<p> The polygon attributes captured include surficial material, texture, age, surface expression, and geomorphological processes. </p>
<p> Line features include geological contacts, glacial limits, glacial landforms (cirques, arêtes, eskers, meltwater channels, moraines), and non-glacial landforms (faults, lineaments, landslides, escarpments).</p>
<p> Point features include field station, fossil and sample locations, glacial landforms (erratics, kames, kettles, drumlins, flutings), permafrost features (pingos, palsas, patterned ground, thermokarst depressions), and other non-glacial landforms (landslides, tors).</p>
<p> The map index provides information on each map publication such as author, map title, map scale, publisher. </p>
<p> These data are valuable for land-use applications in the territory, including: mineral and placer exploration, geotechnical engineering, infrastructure planning, granular resource assessments, permafrost modeling, agricultural assessments, forest management, and biophysical or ecological land classification.</p>
