This spatial layer contains polygons representing 50 m buffers applied to known archaeological sites and historical cemeteries in British Columbia. The 50 m buffer zone represents an area of significant archaeological potential. Buffers are not included for legacy sites or historic places. Due to the sensitivity of archaeological sites, access is provided to authorized users only.

Additional Information


The Archaeological Site Buffers (50 m) layer is a tool to help non-archaeologists engaged in land and resource management decisions to identify areas of significant archaeological potential. Archaeology Branch advises users of archaeological site data that any area within 50 m of a known archaeological site has significant potential to contain protected archaeological material that has not yet been identified or recorded. To assist users in identifying these areas, the Archaeological Site Buffers (50 m) layer provides a clear visual representation of the 50 m archaeological potential zone.

Data Quality

Please note the following data accuracy and completeness issues:

(1) The Archaeological Site Buffers (50 m) layer only shows buffers, not the known site boundaries; therefore, it must be viewed conjunction with a layer that displays known site boundaries.

(2) The layer is updated every Saturday.

(3) All known archaeological sites and cemeteries in the Provincial Inventory have been buffered by 50 m for archaeological potential. The 50 m buffer is arbitrary and may not represent the true extent of archaeological potential in all cases. The buffering does not take into account archaeological site type, previous archaeological study, or topographic surroundings. A professional archaeologist should be engaged to review and confirm archaeological potential.

(4) Archaeological potential buffers are included for historical cemeteries because some cemeteries are known to contain old unmarked graves outside of cemetery boundaries.

Object Description


Comments: Polygon layer containing 50 metre buffer of known archaeological site boundaries protected by the Heritage Conservation Act in the province of British Columbia.

Column Name Short Name Data Type Data Precision Comments
BORDENNUMBER VARCHAR2 13 BORDENNUMBER is a user maintained unique identification number. This is a primary key. In Canada, all archaeological sites are coded by what is known as the "Borden System". It assigns each location a sequence of 4 letters [DcRu] and a number [4] relating to a fixed map code. This is known as the Borden Number.
REGISTRATIONSTATUS VARCHAR2 20 REGISTRATIONSTATUS indicates the registration status. There are 5 options that can be chosen from a drop-down list to populate this column: Decision Pending, Federal Jurisdiction, Legacy, Registered, and Registry Candidate.
ISHERITAGESITE VARCHAR2 1 ISHERITAGESITE indicates if a site is a heritage site or an archaeological site. Heritage sites are denoted as Y or N. Archaeological sites are denoted as NULL.
FEATURE_AREA_SQM NUMBER 19 FEATURE AREA SQM is the system calculated area of a two-dimensional polygon in square meters.
FEATURE_LENGTH_M NUMBER 19 FEATURE LENGTH M is the system calculated length or perimeter of a geometry in meters.
SHAPE SDO_GEOMETRY 1 SHAPE is the column used to reference the spatial coordinates defining the feature.
OBJECTID 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.
