A legally defined Islands Trust polygon was drawn from metes and bounds descriptions as written in Letters Patent for the Islands Trust 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:

Data and Resources

Dataset Extent

Latitude: 48.0° to 60.0°
Longitude: -139.5° to -113.5°

Additional Information


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


Short Name: ABMS_ITRST
Comments: ABMS_ISLANDS_TRUST_SP contains the legally defined Islands Trust administrative boundary area in the Province of British Columbia. This spatial layer contains one feature.

Column Name Short Name Data Type Data Precision Comments
LGL_ADMIN_AREA_ID AA_ID NUMBER 10 An operationally-generated unique identification number, e.g., 1, 2,3.
ADMIN_AREA_NAME AA_NAME VARCHAR2 200 The authoritative, officially approved name given to the Administrative Area, e.g., Islands Trust.
ADMIN_AREA_ABBREVIATION ABRVN VARCHAR2 40 A short form or commonly-known acronym for the Administrative Area name, e.g., ISLTRST (Islands Trust).
ADMIN_AREA_BOUNDARY_TYPE BDY_TYPE VARCHAR2 20 BOUNDARY TYPE is a high-level grouping of Administrative Areas used to categorise features when reporting, e.g., Census, Legal, Administrative.
ADMIN_AREA_GROUP_NAME AA_PARENT VARCHAR2 200 The name given to the larger administrative area (if there is any) of which this feature is a member, e.g., Province of BC (This would be the ADMIN_AREA_GROUP_NAME of the feature called "Islands Trust").
CHANGE_REQUESTED_ORG CHNG_ORG VARCHAR2 30 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, MMAH.
UPDATE_TYPE UPT_TYPE VARCHAR2 50 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 The date and time the record was last modified.
MAP_STATUS MAP_STATUS VARCHAR2 12 That the digital map has been appended to Letters Patent of the administrative area and has received cabinet or ministerial approval, i.e., "Appended": the digital map has been appended to Letters Patent of the municipality, electoral area, regional district or improvement district and has received cabinet or ministerial approval. The map is referred to as the legal map and forms Schedule 1 to Letters Patent. "Not Appended": the digital map exists but currently there is no legislative mechanism that enables the map to be appended to Letters Patent in the absence of a request for a boundary amendment. In other words, while the digital map is the exact representation of the administrative boundary, it is not considered legal until appended to Letters Patent. If there is a discrepancy in the boundary, the written metes and bounds prevail. Null values are permitted for Administrative Areas for which the map status does not apply.
OIC_MO_NUMBER OC_M_NMBR VARCHAR2 7 The most-recent Order-In-Council (OIC) or Ministerial Order (MO) identifier for a particular administrative area. This number is used in conjunction with the OIC_MO_YEAR and the OIC_MO_TYPE to determine the official OIC or MO Number, which is usually in the form ###/YY(YY), e.g., where OIC_MO_NUMBER is 245, the OIC_MO_YEAR is 2013 and the OIC_MO_TYPE is "OIC", the latest OIC for this administrative area is OIC 245/13 that was enacted into law in 2013. Similarily, where OIC_MO_NUMBER is 103 and the OIC_MO_YEAR is 2019 and the OIC_MO_TYPE is "MO", the latest Ministerial Order for this administrative area is MO 103/2019 enacted into law in 2019.
OIC_MO_YEAR OC_M_YR VARCHAR2 4 The four-digit year that the most recent Order-In-Council or Ministerial Order was approved, e.g., 2014.
OIC_MO_TYPE OC_M_TYPE VARCHAR2 20 The short acronym that determines the type of identifier used in the OIC_MO_NUMBER, e.g., OIC (Order-In-Council), MO (Ministerial Order), OTHER (The boundary was issued using a procedure outside of the traditional mechanisms).
WEBSITE_URL WBST_RL VARCHAR2 254 An Internet URL link to additional project information and/or files related to the OIC_MO_NUMBER.
IMAGE_URL IMAGE_URL VARCHAR2 254 An Internet URL link to additional image files related to the OIC_MO_NUMBER.
AFFECTED_ADMIN_AREA_ABRVN AFCTD_AREA VARCHAR2 120 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., NCRD-EA E / NCRD-EA H. If a record has the value "NCRD-EA E / NCRD-EA H" for AFFECTED_ADMIN_AREA_ABRVN, an ADMIN_AREA_ABBREVIATION of Prince Rupert, an OIC/MO (OIC_MO_NUMBER) value of 501/14, an OIC/MO Year (OIC_MO_YEAR) value of 2014, and an Administrative Area Group Name (ADMIN_AREA_GROUP_NAME) of North Coast Regional District, then the interpretation is that OIC 501 in the year 2014 for Prince Rupert also affects the boundaries of Electoral Areas NCRD-EA E and NCRD-EA H in the North Coast Regional District.
FEATURE_AREA_SQM AREA_SQM NUMBER 19 The system calculated area of a two-dimensional polygon in square meters.
FEATURE_LENGTH_M LENGTH_M NUMBER 19 The system calculated length or perimeter of a geometry in meters.
SHAPE SHAPE SDO_GEOMETRY 1 The column used to reference the spatial coordinates defining the feature.
OBJECTID OBEJCTID NUMBER 38 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 A binary column used by spatial tools to store annotation, curve features and CAD data when using the SDO_GEOMETRY storage data type.
