BASE MAPPING & GEOMATIC SERVICES

Our MissionTo manage the Provincial Baseline Atlas as a corporate service for all government ministries, industry, business, academia and the public, in support of economic development and sustainability through better decisions.

► a 100+ years institution evolving from paper maps and gunther’s chain to digital data and satellites and from serving simple land settlement / management to very wide ranging, complex and inter-related activities / decisions on the land

MANAGEMENT BUREAUCadastral Map integralto Provincial Base Map

Cadastral parcels and hence the cadastral map are inextricably linked to base mapping components

– Parcel corners are defined by co-ordinate values referenced to the Geodetic Reference System

– Parcel boundaries are described in relation to natural features (e.g. height of land, shorelines, high water marks, etc.)

– Compilation and usability require consistency between all base map elements, standards, and business strategies / flows

– Core Review reaffirmed imagery, topography, cadastre and underlying geospatial reference as mission critical “base mapping” for the province

MANAGEMENT BUREAU

The cadastral map as Provincial Base Map is used as a base for other businesses and value added applications

– Zoning and planning units are often share boundaries with the parcel fabric.

– Local government and utilities use the parcel fabric as a referential base for managing their properties and physical infrastructure elements

– ER&DM use the cadastral base in conjunction with Digital Road Atlas information to plan, monitor and respond to emergency situations

so it is important that a common, corporate base be used to facilitate integration and analysis

MANAGEMENT BUREAU

GVRD Service Benefits• Supports real-time 3D positioning with two proven technologies,

the centimetres-level RTK or the metre-level DGPS operations;• Offers 24/7 managed data service and help desk support;• Reduces costs by eliminating government-regulated radio licences

and also eliminates the need to establish and secure expensive user-owned reference systems;

• Increases productivity with highly portable GPS systems• Provides access to the most modern region of provincial geospatial

reference system, which is endorsed by the GVRD member municipalities; and

• Reduces physical infrastructure costs for the installation, survey, maintenance and replacement of many densely located survey control monuments.

• Potential applications include cadastral surveys, engineering layouts, topographic surveys, GIS mapping, hydrographic surveys, fleet management and similar activities.



MANAGEMENT BUREAU

Testimonials• “Using RTK will enable Coquitlam to derive significant

savings when establishing a baseline control network for subsequent local surveys – in particular, the new real-time GPS will be useful for topographic surveys, photo control for mapping projects, and for surveying remote areas of Coquitlam”Henry Wong, City of Coquitlam

• “The new service is great! Corrections are available on the fly, and coverage is extensive. Most importantly, there is no base station to set up”



MANAGEMENT BUREAU

Testimonials

• “Overall, we have seen significant time and cost savings using the GVRD GPS real-time service and would highly recommend the system to any company who undertakes these types of projects.”Dennis Stock, Engineering Design & Construction, City of Richmond

• “The GVRD Service provides us benefits of reducing our expenditures on survey control by more than all expenditures for the Service, and of extending hydrographic surveys into areas where survey control was previously hard to establish.” Gouin Barford, Discipline Head, Civil Marine Engineering, Public Works and Government Service of Canada



MANAGEMENT BUREAUSubscription Plan

2006 Subscription Fee• The public can have unlimited data access to the GPS real-time

service by subscribing to the following available rate plans:– Annual Rate - $2,400, or– Monthly Rate - $250– Rate plans for the 2007 calendar year will be announced in the
