Vegetation indices quantify the concentrations of green leaf vegetation (chlorophyll)around the globe, in an attempt to monitor and correlate vegetation health and stress. The MODIS vegetation products include the Normalized Difference Vegetation Index (NDVI)and an Enhanced Vegetation Index (EVI). Included in the MOD13C1 product is both NDVIand EVI, so both have been provided for the CAFF Dedicated Pan-Arctic Satellite RemoteSensing Products and Distribution System. These indices come in a variety of resolutions,but MTRI has provided a monthly global composite on a 0.05° Climate Model GRID(CMG).
The 1 cm resolution vegetation digital height model was extracted using a bare earth model and digital surface model (DSM) derived from unmanned aerial vehicle (UAV) imagery acquired from a single day survey on July 28th 2016, in Cambridge Bay, Nunavut. The mapping product covers 525m2 and was produced by Canada Centre for Remote Sensing /Canada Centre for Mapping and Earth Observation. The UAV survey was completed in collaboration with the Canadian High Arctic Research Station (CHARS) for northern vegetation monitoring research. For more information, refer to our current Arctic vegetation research: Fraser et al; "UAV photogrammetry for mapping vegetation in the low-Arctic" Arctic Science, 2016, 2(3): 79-102. http://www.nrcresearchpress.com/doi/abs/10.1139/AS-2016-0008
The digital canopy model (CNM) is a representation of the height of the canopy. This 3D representation of the arboreal vegetation corresponds to the 2D canopy 2015. If required, the CNM can be coupled with the 2015 [Numerical Surface Model (DSM)] (/city-of-montreal/digital-surface-model) 2015 to obtain more detailed coverage.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
Created for distribution by the GeoYukon application as a comprehensive resource for all publicly available Base Data information in the Yukon government. This data may be used directly by other applications to dynamically display Yukon data; however, it may be subject to change as data sets are updated or added.

A list of the site series ecological units of the current biogeoclimatic ecosystem classification. Site series are subdivisions of the biogeoclimatic subzone/variant, and describe sites capable of producing the same mature or climax vegetation unit (plant association or sometimes, subassociation). Site series are described in the Regional Field Guides to Site Identification. Site and soil conditions, and the vegetation community, are used to identify site series
A list of the various 'regional' (zone/subzone/variant/phase) ecological units of the current biogeoclimatic ecosystem classification. At this 'regional' level, vegetation, soils and topography are used to infer the climate and to identify geographic areas that have relatively uniform climate. These geographic areas are termed biogeoclimatic units. The basic biogeoclimatic unit is the Subzone. These units are grouped into Zones and may be further subdivided into variants based on further refinements of climate (e.g., wetter, drier, snowier). The map units of the Biogeoclimatic map are mapped to the highest possible thematic resolution - subzone or variant. In some cases, where further sampling is required to define the unit climatically, polygons are labelled as an undifferentiated unit (e.g. CWH un)
The current and most detailed version of the approved corporate provincial digital Biogeoclimatic Ecosystem Classification (BEC) Zone/Subzone/Variant/Phase map (version 12, September 2, 2021). Use this version when performing GIS analysis regardless of scale. This mapping is deliberately extended across the ocean, lakes, glaciers, etc to facilitate intersection with a terrestrial landcover layer of your choice
The Land Cover Dynamics MODIS product is a yearly product that represents thetiming of vegetation phenology globally. Sub-datasets include vegetation growth, maturity,senescence, and dormancy. This product also includes the NBAR-(Nadir Bidirectionalreflectance distribution function (BRDF) adjusted Reflectance) based EVI, in part becausethe EVI is used to create the Land Cover Dynamics. The Land Cover Dynamics product uses both Terra and Aqua MODIS data. Version005 (provided) has a 500 m spatial resolution, which is an improvement from the 1,000 mversion 004 product. This product is only available in MODIS tiles, so the tiles needed tocover the CAFF pan-Arctic region has been downloaded but not clipped to the pan-Arcticextent at this time.
Location of long-term vegetation (including fungi, non-vascular and vascular plants) monitoring sites and programs. Comes from the Arctic Terrestrial Biodiversity Monitoring Plan is developed to improve the collective ability of Arctic traditional knowledge holders, northern communities and scientists to detect, understand and report on long-term change in Arctic terrestrial ecosystems and biodiversity. The report can be seen here http://www.caff.is/publications/view_document/256-arctic-terrestrial-biodiversity-monitoring-plan The monitoring locations are place over the Circumpolar Arctic bioclimate subzones (CAVM Team 2003) http://www.caff.is/flora-cfg/circumpolar-arctic-vegetation-map
