Technical Thematic Report No. 17. - Monitoring ecosystems remotely: a selection of trends measured from satellite observations of Canada
Tree crown density > 10%. Includes:
|Shrubland||Tree crown density < 10%, shrub cover > 40%|
Note: Most wetlands will be included here
|Grassland||Tree or shrub cover <10%, herbaceous vegetation present|
|Low Vegetation and Barren||Includes areas vegetated with lichens, heather, herbs, shrubs (<40% of vegetation is shrubs, otherwise it will be classified as “Shrubland”), bare soils, or rock outcrops|
Note: while old and new fire scars make up the majority of this class, areas of harvest, mining, and severe insect defoliation may also be included
|Urban||Land covered by buildings and other artificial structures. Confusion with other non-vegetated classes may occur for small urban areas. |
Note: Urban area in this report is status as of 1996-1997 from the National Atlas. AVHRR data is too coarse to map changes in urban area over time.
|Snow/ice/glacier||Land covered with permanent ice or snow. |
Note: Errors exist in this class for the Pacific Maritime and Boreal Cordillera ecozones+. These errors have been corrected in the 2005 land cover map, but are not corrected in the transition matrices. Changes in this class over time therefore cannot be discussed.
|Inland Water||Land covered with water in liquid form|
Note: The ‘inland water’ class extent is taken from the National Atlas. Changes in inland water are not mapped due to the dynamic nature and high variability of this class.
