3.0 Mapping Conventions
The following rules and standards apply to TEM in British Columbia. A list
of core polygon attributes, which must be captured in the map database,
are presented in Section 4.1.
3.1 Ecoregion/Biogeoclimatic Units
Ecoregion and biogeoclimatic polygons are labeled according to the ecoregion
and biogeoclimatic units they represent. Ecosection units are given a three-letter
code. Biogeoclimatic units receive codes of up to nine characters in length
(Figure 3.1). Both ecosection and biogeoclimatic unit codes are available
on the TEM website (see Appendix B).
| Figure 3.1 | Symbols
for Biogeoclimatic Units |
The ecosection unit symbol is generally presented above the biogeoclimatic
unit symbol, with both enclosed by a circle (see Figure 3.2). A new symbol
is placed on the map whenever one or both of the units change.
