Features in the Hydrology - Line layer are representations of creeks, streams, and rivers for the City of Whitehorse. Data was modeled using the NENA NG9-1-1 GIS Data Template (NENA-REF-006. 2 -202 2 ). Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

The field work for the inventory was carried out during the winter of 2004/2005 with the project delivered by the contractor in October 2005. Delineation was based on 1:10,000 black and white photography acquired by the City of Whitehorse in 2001. Mapping and DTM were available for this project based on the 2001 photography.

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. 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 [YGS integrated data system](https://data.geology.gov.yk.ca/Compilation/33#InfoTab) (YGSIDS) or GeoYukon. A .lyr file is [provided](https://data.geology.gov.yk.ca/Compilation/33#InfoTab) to symbolize feature classes and differentiate overlapping maps at different scales. Additionally, there is a surficial geology map index. The polygon attributes captured include surficial material, texture, age, surface expression, and geomorphological processes. Line features include geological contacts, glacial limits, glacial landforms (cirques, arêtes, eskers, meltwater channels, moraines), and non-glacial landforms (faults, lineaments, landslides, escarpments). 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). The map index provides information on each map publication such as author, map title, map scale, publisher. 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.

Yukon Place Names are derived from the Yukon Place Name Program Database, which is the Government of Yukon's repository for storing toponymic data. The database includes information on the location, history and status of official place names in the Yukon. Although the data has been checked for correctness, there still may be errors. Please report any errors to the Yukon Toponymist: [Geographical.Names@yukon.ca](mailto:%20Geographical.Names@yukon.ca) If you wish to propose a name for a geographic feature please visit [https://yukon.ca/en/geographical-place-names](https://yukon.ca/en/geographical-place-names) .
