An Integrated Survey Area is an administrative area within which a British Columbia Land Surveyor is required to integrate cadastral surveys with a network of control monuments under the Integrated Survey Area. Tantalis is an information system designed specifically for the needs of the complex workings of Crown Land Registry and to provide automated support for all aspects of Crown land administration. It was designed to provide a foundation for integrating spatial data associated with mapping of survey plans and administrative boundaries with attribute data associated with legal documents and administrative records. The system records and tracks the sale, survey, license, access, return, and restriction of Crown land in British Columbia. This new system introduced the capacity for further applications, to revolutionize access and processing of Crown land information

Additional Information


Tantalis is a computerized land information system designed to fulfill desktop access to an integrated database containing all records-both spatial and textual-needed for the business of provincial land administration. The business needs to be supported by Tantalis are diverse and are summarized as follows. - Track applications for the use of Crown land from the point of initial enquiry through to the issuing of legal documents and registration of interest. Tools were needed to support the extensive consultation and evaluation activities that take place during the application process prior to the issuing of any legal documents; - Maintain a registry of interests in Crown land consisting of legal documents associated with all land transactions as well as all historical survey information; - Maintain a spatially continuous fabric of all land parcels, administrative boundaries and reserves over Crown land; - Support the ongoing administration of Crown land tenures.

Lineage Statement

80% accurate. With the exception of unsurveyed (digitized) boundaries, the cadastral data is captured at a 1:1 scale.

Object Description


Short Name: TA_ISA_SVW
Comments: TA_INTEGRATED_SURVEY_AREAS_SVW contains the spatial representation (polygon) of the areas providing official survey control through a standard vertical and horizontal reference system to support mapping, engineering, surveying and other works. The view was created to provide a simplified view of this data from the administrative boundaries information in the Tantalis operational system. These areas are established by Order pursuant to section 12(1) of the Land Survey Act.

Column Name Short Name Data Type Data Precision Comments
ADMIN_AREA_SID ADMIN_AREA NUMBER 38 ADMIN_AREA_SID is a system-generated sequential identifier that uniquely represents the integrated survey area amongst all administrative areas stored in the Tantalis system.
INTEGRATED_SURVEY_AREA_NAME ISA_NAME VARCHAR2 50 INTEGRATED_SURVEY_AREA_NAME is the commonly used reference in notices and correspondence for the areas established under section 12(1) of the Land Survey Act. For example, KAMLOOPS INTEGRATED SURVEY AREA 23 refers to the extent in central British Columbia British Columbia providing official survey control.
FEATURE_CODE F_CODE VARCHAR2 10 FEATURE CODE is a standard alphanumeric code to identify the type of feature represented by the spatial data. A feature code is most importantly a means of linking a feature to its name and definition. For example, the code GB15300120 on a digital geographic feature links it to the name "Lake - Dry" with the definition "A lake bed from which all water has drained or evaporated." The feature code does NOT mark when it was digitized, what dataset it belongs to, how accurate it is, what it should look like when plotted, or who is responsible for updating it. It only says what it represents in the real world. It also doesn't even matter how the lake is represented. If it is a very small lake, it may be stored as a point feature. If it is large enough to have a shape at the scale of data capture, it may be stored as an outline, or a closed polygon. The same feature code still links it to the same definition.
SHAPE SHAPE SDO_GEOMETRY 64 SHAPE is an ArcSDE column that references the spatial feature's coordinate geometry.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a required attribute of feature classes and object classes in a geodatabase.
