3  Introduction

3.1 Business Requirements Overview for Building the Single parcel Fabric (BCSpatial) The goal is to create a single parcel fabric for the province of BC in accordance with the original ICIS mandate. The challenges that have prevented this from occurring have mostly been around having all data supplied to meet the established ICF standard. The initial task for resurrecting this project as the Number 1 priority for ICIS is to review the business requirements for each member segment and use these requirements to review the standards and project phases to ensure the feasibility and value of the resultant single fabric.

3.2 ICIS Member Segment ICIS is comprised of 3 member segments: •	Provincial Government •	Utility •	Local Government

In order to assess the requirements, the ICIS board members will be interviewed to establish these requirements. As per the June 26, 2008 ICIS board planning session, these interviews will be conducted during the August-October time frame with the preliminary results compiled to date ready for review at the September Board planning session. Also in accordance with the June 26th meeting, the interviews will be conducted individually with the provincial and utility members and collectively with the local government members.

4  Single Parcel Fabric System Requirements

NOTE: This section will contain the list of requirements identified during the analysis. Each requirement will represent one unambiguous statement. For example “the cadastre shall be updated with local government updates on a weekly basis”. Requirements that cannot be measured or tested will be difficult to quantify.

Requirements for creating the single parcel fabric for the province of BC will be divided into four categories:

•	Business / Functional Requirements; •	Input/export Requirements; •	Performance Requirements; and •	“Other” Requirements;

4.1 Business / Functional Requirements

Business / Functional Requirements table:

Req. #	Requirement	Description	Priority 1	All of the real parcels present in the fabric and only the real parcels. 2	All of the assigned addresses on each parcel present and accurate. 3	Relative size and position of the parcels including inter-jurisdictional boundaries accurate to good representational accuracy. 4	Other agency information including utilities to good representational accuracy. 5	All data at 10cm accuracy.

4.2 Input/Export Requirements

This section will list Input & export requirements. Those are requirements that affect/interact with member group systems (internal & external) and integrate to the parcel fabric.

Input table: What data is supplied currently, will be or could be. Req. #	Data	Description	Currency	Accuracy	Source 1	Stream inventory	Ministry of Environment uses LG data

Export table: What data is required currently and in the future.

Req. #	Data	Description	Currency	Accuracy	Source 1	ALR Data	Agricultural Land Reserve data 2	Digital Road Atlas	911 purposes Forestry roads 3	Orthos	Imagery needed 4	Education parcels	Roads & buildings – e.g. UBC and UVic 5	Federal data	Foreshore, Airports, Port Authorities, First Nations land, Harbour Commission

4.3 Performance / Availability Requirements

This section will enumerate the Performance requirements; those are minimum, measurable requirements that usually encompass a series of unique requirements. For example, the single parcel fabric must be available for access and extract during standard business hours with 99.9% up time.

Performance Requirements table:

Req. #	Performance Requirement	Availability 1	Strategy needed to: •	Get the basics •	Initiate projects •	Next steps 2	Clarity on definitions and standards for ‘parcel’ and ‘accuracy’.

4.4 “Other” Requirements

This section will be used to address “Other” needs that cannot be assigned to a specific area. Brainstorming ideas on how the single parcel cadastre could be improved should be addressed in this section:

Req. #	Requirement	Description	Priority# 1	Create more sustainability 2	Carbon neutral target (2012) – eco-audit capabilities? 3

Benefits: 	Relative accuracy more important than spatial accuracy. 	Spatially aligned boundaries with neighbouring jurisdictions more value in rural areas. 	Regional focus for economic development. 	911 purposes. 	High value from Utility data being aligned. 	Opportunity to target funds to data sets based on need or level of improvement. 	Standard for parcel data that will improve most over time. 	Concept of data ‘as is’.

Challenges: 	Low value of parcel data from other jurisdictions. 	Low priority for LG to align boundaries – minimal resources assigned. 	Spatial accuracy a ‘moving target’. (NAD 83 vs. new SCR National Standards). 	High costs for increased accuracy > little utility > low priority. 	New data requires skewing of old data to achieve relative accuracy. 	Areas without survey control monuments can only achieve 5 m with best GPS technology. 	Terms of reference needed for future discussions on ‘Parcel’ and ‘Accuracy’. 	Two standards for parcel data. 1) provincial government and 2) local government.

Require strategy that recognizes: 	ICF mandated Accuracy is not realistically achievable 	ICIS webmap is a gradually improving spatially aligned document. 	Assessment of what we have is critical for currency and accuracy 	Spatially aligned frame of regional boundaries within the province can be used to work inward to municipal districts. 	Areas without boundary data can be defined by surrounding areas and their boundaries. ‘White space’ creates need to provide data to achieve comprehensive coverage.
