Integrated Cadastral Fabric

The Integrated Cadastral Fabric (ICF) is a single, integrated and consistent digital mapping of the location, extentand nature of land parcels (both Crown and privately held) in British Columbia. It is intended to represent the current groundstate in a continuous, non-overlapping fabric of private and crown-administered surface land parcels which have been defined by various surveys (e.g. including Land Act and Land Title Act surveys).

Tantalis Spatial

Tantalis spatial data consists of a seamless fabric of current and historical Crown Land survey data and Crown land tenure information (also called cadastral information) spanning the extent of British Columbia. It also includes several types of Administrative areas ( e.g. Land District, Regional District, Municipalities, etc.) relevant to land disposition.

Digital Air Photos

Black and white aerial photography is available for all of British Columbia at a variety of scales and, in some areas, dating back more than fifty years. Colour aerial photography is becoming increasingly available, particularly in the Okanagan, Kootenay and Cariboo areas.

Gridded Digital Elevation Model (DEM) Map Sheets

A Gridded Digital Elevation Model (DEM) Map Sheet is a 1:250 000 map sheet with additional slope, aspect, and hillshade data derived from the Terrain Resource Information Management (TRIM) program's DEM.

Hillshade

Hillshade - TRIM products are a derivation of the BC gridded Digital Elevation Model (BC DEM) consisting of eight distinct raster products, presented in two different common planar projections, in file formats appropriate to the file content. The BC DEM files use the National Topographic System (NTS) at 1:250 000 scale (250K blocks) as a delivery basis and have a grid spacing of 25 metres.

Orthophotos

An orthophoto is a geometrically corrected aerial photograph that displays ground features to be displayed in their true ground position with a constant scale throughout the image.

Satellite Imagery

Satellite imagery are photographs of Earth or other planets made from artificial satellites. Satellites orbiting Earth have an orbit, elevation and time intervals to cover the globe and image the same area. Examples of these satellites are Landsat, SPOT, IKONOS, Quick Bird and IRS. Active satellites record reflected radiations which the sensors will send to earth surface. These are Radar Satellites such as Canadian RADARSAT 1 and 2.

1:250 000 Base Map (NTS)

Unlike the Terrain Resource Information Management (TRIM) product which involves direct data compilation, the 1:250 000 data has been produced by scanning various lithographic layers of the published paper map series.

BCACS GPS Base Station Data

The BC Active Control System (BCACS) network comprises permanent, continuously operating Global Positioning System (GPS) base stations linked to Victoria via telecommunication networks. It provides raw GPS observables from GPS receivers located on very precise and accurately located geodetic control monumentation.

BCACS Post-mission Data is available for the whole province by subscription or on a pay-per-download basis.

BCACS Municipal Data - CRD

The BCACS^m is a system which provides GPS corrections in post-mission and real-time using the standardized Provincial coordinate system. Real-time communication is supported via a UHF radio link and/or wireless PCS link (i.e. cellular telephone). Real-time accuracy levels range from approximately 1m (using RTCM code corrections and a mapping grade GPS receiver) to centimetre level (using dual frequency survey grade receivers).

The BC ACS^m - CRD provides the capability to acquire precise control anywhere within the CRD without the requirement to have two GPS receivers or using  costly traversing to bring control in from distant monuments. All the user needs is a single GPS receiver capable of achieving the accuracy they require, and an off-the-shelf radio receiver. Subscriptions to the correction signal can be obtained from the CRD.

BCACS Municipal Data - MV

The BCACS^m is a system which provides GPS corrections in post-mission and real-time using the standardized Provincial coordinate system. Real-time communication is supported via a UHF radio link and/or wireless PCS link (i.e. cellular telephone). Real-time accuracy levels range from approximately 1m (using RTCM code corrections and a mapping grade GPS receiver) to centimetre level (using dual frequency survey grade receivers).

This real-time GPS Service was developed as a partnership between Crown Registry and Geographic Base and the Greater Vancouver Regional District, and the municipalities comprising the Metro Vancouver (MV). CRGB and the MV are working in partnership with selected private companies to build this system to support high precision real-time GPS applications within the MV. The Service supports real-time metre level positioning (DGPS) for mapping and GIS applications and positioning at the level of a few centimetres (RTK) horizontally and vertically for survey and engineering applications.

Geoid Model Data

The BCACS^m is a system which provides GPS corrections in post-mission and real-time using the standardized Provincial coordinate system. Real-time communication is supported via a UHF radio link and/or wireless PCS link (i.e. cellular telephone). Real-time accuracy levels range from approximately 1m (using RTCM code corrections and a mapping grade GPS receiver) to centimetre level (using dual frequency survey grade receivers).

MASCOT Geodetic Data

MASCOT is a geodetic database management and processing system based on Oracle, C, PL/SQL and FORTRAN numerical computing within a Sun Microsystem Solaris computer architecture. The MASCOT Website provides access to the final product on the database. This subscription allows the user to access the MASCOT database and download data up to the subscription limit. If you do not want a subscription to the MASCOT service, then the user can still "pay-per-download" by accessing the MASCOT website and applying for a standard account.
