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.

The BCACSm 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
ACSm - 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. Read more >>

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. Read more >>

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. Read more >>

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.

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.

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.
