| ALR - Agricultural Land Reserve | |
|
An area set
aside for the more-or-less exclusive use of agricultural activity. The ALR
system was set up province-wide in the early 1970s on the basis of Canada
Land Inventory classification of land suitable for agriculture. The ALR
has degraded over the years by wider interpretations of economic and
social, not just physical, exclusions. openet.ola.bc.ca/geog270/glossary.html

|
| Biogeoclimatic subzone | |

‘Bio’
- indicates the biological nature of the ecosystem, ‘geo’ - indicates the use of soils and geology in the classification,
"climatic"
involves overriding climatic factors in the classification.
The combination of geology, vegetation and climate concepts form
the basis for division of Biogeoclimatic Zones in British Columbia.
Together,
the three levels Bio, Geo and Climatic are used to classify any site in BC
into an ecosystem. In British Columbia, there are 14 biogeoclimatic zones
identified. http://selkirk.ca/rr/bec/zones/pdf/whatis.pdf |
|
| Community Mapping | |
| Data that was collected by communities (general observations about a site
of interest). Geographic extents: all of BC.
|
|
| Cumulative Wildlife Rating | |
|
Mapping which rates the quality of habitat for 10 wildlife species
using the sensitive ecosystem mapping. Refer to Bella Vista
Documents link off of abnc’s site.

|
| DEM image hillshade | |
|
Digital Elevation Model: a computerized representation of an elevated surface. Relief shading is used to visually enhance the terrain features by simulating the appearance of the effects of sunlight falling across the surface of the land.

|
| Hydrology | |
| Study
of the distribution, conservation, and use of the water of the earth and
its atmosphere
|
|
| Imagery | |
| Orthophotos
and other satellite imagery. Geographic Extents: Vancouver Island, Lower
Mainland and other selective.
|
|
| Infrastructure | |
| Local
government features such as cadastral, detailed road network for various
municipalities, detailed watercourses, watercourses classification (Surrey
and Langley only), road network, cities and place names.

| Traditionally,
metadata is understood as data about data http://www.ukoln.ac.uk/interop-focus/presentations/cimi/taiwan/rdf/iap-html/sld002.htm

| NASA Landsat | |
| Landsats
are a series of satellites
built and launched by the National Aeronautics and Space Administration
(NASA). The Landsat satellites observe the Earth, and the data that
they collect have been used for almost 30 years to study the Earth's
environment, resources, and natural and man-made changes on the Earth's
surface. Landsat
data are the standard for Earth observations, and Landsat is the only
system of its type with the mission to collect, archive, and distribute
data of all the Earth's land surface.

| Orthophotos | |
| Are
photos that have been fitted into a standard map projection so that they
contain the qualities of both maps and photographs. Like maps, they have
only one scale, which allows for accurate measurements of distances,
angles, and areas to be made directly from their surface. Like photographs
they depict features as they truly are (without any symbolization). www.richlandmaps.com/training/glossary/m_p.html |

| Riparian | |
| Of,
on, or relating to the banks of a natural course of water

|
| SEI - Sensitive Ecosystem Inventory | |
| ecosystem
is defined as a portion of landscape with a relatively uniform dominant
vegetation; sensitive ecosystems are those which are fragile
and/or rare. SEI
identifies
the remnants of these rare and fragile terrestrial ecosystems using air
photo interpretation and field surveys http://www.shim.bc.ca/atlases/sei/seidoc.htm

|
| Stock Status - Stock | |
|
A
biologically discrete population. Fish species are made up of an aggregate
of stocks. Term refers to the
condition of a population.

|
| SHIM - Sensitive Habitat Inventory Mapping | |
| SHIM
data provided by various groups. Feature types include: fish habitat,
culvert, enhancement, modification, obstruction, stream, etc.

| Trim 1:20K | |
| TRIM
Layers (1:20,000 scale) including lakes, rivers, elevation contours lines,
roads, land cover and transport structures. |
