11
Question 5

• Key characteristics (g) Accuracy of data
  (absolute)
• Absolute accuracy relates to the relative
  position of the data with respect to the
  reference system, it answers the question of how
  accurate the data is relative to its true
  position.
• Better than 1m 50
• 1m to 2m 29
• 2m to 5m 21
• 5m to 10m 29
• 100m or worse 21

12
Question 5

• Key characteristics (h) Accuracy of data
  (relative)
• Relative accuracy relates to the relative
  position of the data with other data in the same
  dataset. Usually, this accuracy is of a higher
  standard than absolute accuracy.
• Better than 5cm 43
• 5cm to 10cm 21
• 10cm to 1m 21
• 1m to 5m 29
• 5m to 10m 21
• 10m or worse 21

  Service)
• Technical information (e) WFS
• No respondents currently use to WFS (Web Feature
  Service)

18
Question 7

• Technical information (f) Is seamless cadastral
  data important for your business?
• 64 of respondents agree that seamless cadastral
  data is important for their business.

19
Question 8

• Do you have any cadastral needs that are not
  being met?
• Federal access to national cadastral data.
• Each Dept has to negotiate federal access to
  provincial data separately.
• Cost is often the prohibitive factor often it is
  not feasible to purchase an entire data set
  (license), when ad-hoc purchases will suffice.
• Location and identity of First Nation Lands.
• Current mismatch between Indian Land Registry
  System and Canada Land System (CLS) but this is
  being addressed by both depts under a joint
  project.

20
Question 9

• How important is it for your organization to move
  towards a common standard for modeling between
  different agencies providing cadastral data?
• 93 said High or medium
• This makes data sharing more effective
• Sharing information is crucial in research,
  policy and decision and monitoring and reporting
  work.
• it is important to facilitate data exchange.
  Seamless integration of multiple types of data is
  a dream at this point.
• Moderate from a core RP perspective but Very High
  for branch program needs (e.g. during emergencies
  need to be able to share data quickly)

21
Question 9

• How important is it for your organization to move
  towards a common standard for modeling between
  different agencies providing cadastral data?
• 7 said Low
• Cadastral information for 25,000 or so federal
  real properties is not a high priority - it is
  held in provincial systems and should be subject
  to oversight (survey/ title) only in relation to
  transactions or litigation

22
Question 10

• When integrating cadastral data to other
  geospatial information, what challenges and
  issues to you face?
• Creating data models for civil infrastructure
  systems that are more than just MAPS.
• Unique parcel ID to link attribute information
• Probably, the biggest challenge of integrating
  our cadastral data with other geospatial data is
  alignment and accuracies.
• Often metadata is not included with the purchase
  of data and extra time is required to integrate
  it into the project.
• Lack of standards
• Licensing agreements

23
Question 11

• Additional requirements?
• Cadastral information for 25,000 or so federal
  real properties is not a high priority - it is
  held in provincial systems and should be subject
  to oversight (survey/ title) only in relation to
  transactions or litigation.
• Low cost (free) access to government-supplied
  data.
• Need to ensure continued data coming from source.
• Timeframe for availability.
