Framework is
more than Data
An interesting case !
The project is to ...
- Build the best road network and other
informations as park, camping, forest and lake.
- This dataset will be use by traveler
to find their way to attraction or accomodation !
- The Ottawa - Outaouais area is needed
.
What kind of information do we have ?
Find the available data
Geomatics Canada 100% 90-94 50-10 OK
Province Québec 75% 92-97 10 m. OK
Ottawa Carleton 10% 94-97 1 m. Good
Canada post 100% 96-97 100-10 Great
Good - but !
Data analysis
- Conclusion
- none of the above product answer this
specific need
- Actually, what we need is to build our
own !
- Use the best geometric / accuracy data
available - assemble it like a puzzle
- Transfert the attribute value from Canada
post data to the new dataset
- What do we need to do that or what kind
of problem do we facing of ?
Problem # 1
Various data accuracy
- Accuracy change from product to product
and from area to area
- We must put all the information we need
at the same level of accuracy.
Planimetric correction
Problem # 2
Edge match
Horizontal integration
Problem # 3
More then 1 representation for the same
phenomena
Problem # 4
More then 1 representation use the same
space
Users need tools
- For problems such as the exemple
- Data Alignment Layer is part of it
- For permanent Data Bases links
- Department - Department
- Federal - Provincial / Provincial -
Municipal
- Anybody - Anybody
Proposed action
- I recommend
- To create a Special Interest Group to
further define the framework from the tools and processes perspective.
Benefits of promoting tools and processes in
Framework Data
- Its a common problem
- Federal, Provincial, Municipal and private
- Applicable to all users
- Markettable technologies
- Fosters collaboration
- Win … Win … Win
Why a Special Interest Group
- We need to dissociate Data from Tools
- To create focus and momentum
- There is work to be done
- To define and frame
- To legitimate the work
