Integrating CAD & GIS in a Municipal Environment
- 2. The City of Vancouver 3rd Largest City in Canada Home of the 2010 Winter Olympics and Paralympics Population 580,000 Over 2,000,000 in Greater Vancouver area Covers 113 sq. kilometers. 44 sq. miles
- 3. Engineering Department Plan, build, improve, manage, and maintain the following services in accordance with policies set by City Council: – Water supply and distribution – Sewerage and drainage – Utility corridor management – Street lighting and traffic signals – City communications system – Streets, lanes, boulevards, sidewalks, and bridges – Solid waste reduction, refuse collection, disposal, and street cleaning – Transportation
- 4. In the beginning…. GIS system in the early 1990’s had rudimentary tools to extract line work into CADD format Process had many steps, was rather clunky, and only a few of the design branches bought in. As a result CADD files began to pile up in local drives Data within was of little value to the rest of the organization. Efforts made to develop a GIS interface to our CADD system
- 5. And then we created…. In the late 1990’s the City created a dedicated CADD Server CADD Server stored base files that had been generated from the GIS system Made use of drawing templates that ensured that individual designers shared common libraries and a common coordinate system The base files were static files updated from GIS on a scheduled basis (often monthly).
- 6. Ground vs. Grid (1) Streets Division began using Total Stations to collect survey data and generate electronic field books. Data was downloaded and cleaned up and passed on to the designers Conflicts arose with our Land Survey Branch who were managing the GIS cadastral base in grid units
- 7. Ground vs. Grid (2) Decision made to build a CADD-based repository for these files In time some of the data was translated to allow it to be overlaid on the GIS data.
- 8. Design to Construction (1) In 2002 moved our GIS data into an spatially enabled GIS database CADD users and GIS users could connect to the geo-database and query the data into a CADD file Ensured that a designer would get the most up-to-date background data for their new design
- 9. Design to Construction (2) Design printed out and sent to Operations who constructed the new infrastructure Field changes manually tracked and passed to office staff for entry into GIS Not every change made it back into the GIS!
- 10. PSAB & Asset Management Began implementation of Enterprise Asset Management in 2007 In part in response to PSAB 3150 City acquired new GIS tools in 2008 to support Asset Management Strategy Asset must be created first in GIS before the work order to construct the asset can be issued Design-based GIS using concept of jobs
- 12. CADD DESIGN GIS ASSET MANAGEMENT
- 13. Key Points for CADD/GIS Integration Get the data into a central repository that is accessible to both your CADD and GIS tools Leverage web mapping solutions as an alternative to costly CADD packages Limit the number of data ‘handoffs’ particularly during design phase There is no ‘single solution’ Business process may need to change
