Legally defined Local Trust Area polygons were drawn from metes and bounds descriptions as written in Letters Patent for the Local Trust Areas in the province of British Columbia.

A polygon dataset that includes all of the administrative areas currently in the Administrative Boundaries Management System (ABMS) is available here.

A complimentary point dataset that defines the administrative areas is also available available here.

Other individual datasets are available from the following records:

Additional Information

Purpose

Administrative boundaries are used by agencies at all levels of government for land use planning, treaty negotiations, emergency management and planning, running elections, conducting demographic analysis and municipal planning.

Lineage Statement

Primary data sources for ABMS include Metes and Bounds legal descriptions from the Letters Patent, ICF (Integrated Cadastre Fabric), TRIM (Terrain Resource Information Mapping), and FWA (Freshwater Atlas). Other sources were used to clarify boundaries (e.g., Tantalis for crown land parcels, legal plans, etc.).

Object Description

Object Name: WHSE_LEGAL_ADMIN_BOUNDARIES.ABMS_LOCAL_TRUST_AREAS_SP

Short Name: ABMS_LTRST
Comments: ABMS_LOCAL_TRUST_AREAS_SP contains legally defined local trust area administrative boundary areas (subdivisions of the Islands Trust) in the Province of British Columbia. This spatial layer contains multipart features.

Column Name Short Name Data Type Data Precision Comments
LGL_ADMIN_AREA_ID AA_ID NUMBER 10 LGL_ADMIN_AREA_ID is an operationally-generated unique identification number, e.g., 1, 2,3.
ADMIN_AREA_NAME AA_NAME VARCHAR2 200 ADMIN_AREA_NAME is the authoritative, officially approved name given to the Administrative Area, e.g., Regional District of Alberni Clayquot.
ADMIN_AREA_ABBREVIATION ABRVN VARCHAR2 40 ADMIN_AREA_ABBREVIATION is a short form or commonly-known acronym for the Administrative Area name, e.g., Tofino (Corporation of the Village of Tofino), RDAC (Regional District of Alberni Clayquot).
ADMIN_AREA_BOUNDARY_TYPE BDY_TYPE VARCHAR2 20 ADMIN_AREA_BOUNDARY_TYPE is a high-level grouping of Administrative Areas used to categorise features when reporting, e.g., Census, Legal, Administrative.
ADMIN_AREA_TYPE AA_TYPE VARCHAR2 50 ADMIN_AREA_TYPE is a low-level grouping of Administrative Areas used to categorise features when reporting, e.g., Province, Regional District., Harbour and Port Authority.
ADMIN_AREA_GROUP_NAME AA_PARENT VARCHAR2 200 ADMIN_AREA_GROUP_NAME is the name given to the larger administrative area (if there is any) of which this feature is a member, e.g., Regional District of Alberni Clayquot (This would be the ADMIN_AREA_GROUP_NAME of the feature called "The Corporation of the Village of Tofino").
CHANGE_REQUESTED_ORG CHNG_ORG VARCHAR2 30 CHANGE_REQUESTED_ORG is the government acronym of the Ministry or sub-org that last requested the change that resulted in the modification of the record, e.g., GeoBC, MCSCD.
UPDATE_TYPE UPT_TYPE VARCHAR2 50 UPDATE_TYPE is a short description of the latest alteration of the feature's geographic or attribute content, e.g., Inserted (added new), Change in geometry.
WHEN_UPDATED UPT_DATE DATE 7 WHEN_UPDATED is the date and time the record was last modified.
OIC_NUMBER OIC_NUMBER VARCHAR2 7 OIC_NUMBER is a single, most-recent Order-In-Council (OIC) identifier for a particular Administrative Area. The OIC_NUMBER is in the form ###/YY where ### is a number, then a forward slash "/" followed by a two-digit Year abbreviation, e.g., 245/13 denotes OIC Number 245 enacted into law in 2013.
OIC_YEAR OIC_YEAR VARCHAR2 4 OIC_YEAR is the four-digit year that the Order-In-Council was enacted into law, e.g., 2014
AFFECTED_ADMIN_AREA_ABRVN AFFCTD_DMN VARCHAR2 120 AFFECTED_ADMIN_AREA_ABRVN is a semicolon-delimited list of the abbreviations (ADMIN_AREA_ABBREVIATION) of Administrative Area boundaries that are affected by the OIC number in the OIC year, e.g., SQCRD-EA E; SQCRD-EA H. If a record has the value "SQCRD-EA E; SQCRD-EA H" for AFFECTED_ADMIN_AREA_ABRVN, an ADMIN_AREA_ABBREVIATION of Prince Rupert, an OIC (OIC_NUMBER) value of 501/14, an OIC Year (OIC_YEAR) value of 2014, and an Administrative Area Group Name (ADMIN_AREA_GROUP_NAME) of Skeena-Queen Charlotte Regional District, then the interpretation is that OIC 501 in the year 2014 for Prince Rupert also affects the boundaries of Electoral Areas SQCRD-EA E and SQCRD-EA H in the Skeena-Queen Charlotte Regional District.
FEATURE_AREA_SQM AREA_SQM NUMBER 19 FEATURE_AREA_SQM is the system calculated area of a two-dimensional polygon in square meters.
FEATURE_LENGTH_M LENGTH_M NUMBER 19 FEATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters.
SHAPE SHAPE SDO_GEOMETRY 1 SHAPE is the column used to reference the spatial coordinates defining the feature.
OBJECTID OBEJCTID NUMBER 38 OBJECTID is a column required by spatial layers that interact with ESRI ArcSDE. It is populated with unique values automatically by SDE.
SE_ANNO_CAD_DATA BLOB 4000 SE_ANNO_CAD_DATA is a binary column used by spatial tools to store annotation, curve features and CAD data when using the SDO_GEOMETRY storage data type.
