An End User Perspective on Implementing Oracle in the Engineering Environment
- 1. Migrating Integrated CAD/GIS Users from File-Based Storage to Oracle Locator S.F. Dept of Public Works – Bureau of Engineering An End user perspective on implementing Oracle in the engineering environment Greg Braswell Manager of Sewer Information MIS-GIS-CAD City and County of SF-Dept of Public Works Bureau of Engineering 1680 Mission ST San Francisco, CA 94103 [email_address]
- 2. SEWER GIS More then Just Maps Hydraulics section, DPW maintains information about the sewer system for the City & County of San Francisco. Data for about 1000 miles of sewer pipes, 27,000 Manholes, 24,000 Catch basins and various structures forming components of the sewer system has been captured in GIS ready format. Data captured include the location, geometry and various attributes of the pipes & node structures. This central GIS data has become one of the core databases to which is used in day to day functionality of the Hydraulics section. Maps Published on the intranet As-Built Viewer -View engineering drawings associated with GIS data Paving/ Sewer project management system Sewer Inspection / TV Taping Management system GIS DATABASE SQL Server database AutoCAD files ESRI shape files EXAMPLES OF USE OF GIS DATA

- 4. The Dream One Big Database of all CAD Drawings Big CAD database updates Asset mgmt database CAD and asset mgmt are completely integrated All happens “In 1 fell swoop” Updates, edits, corrections Easily get out data for all applications Planning and Analysis Modeling Design projects
- 5. Early Attempts Fits and starts Experimenting with Oracle Expensive! Download for free!!! 3-4 attempts to install oracle It finally works! How to connect to work with data? ODCB-Access front end… . We’re good at that… All other applications are in SQL server…. Instructions and how to??? Google! Experimenting with ACAD Directions say “See database admin”…. What a sec, we are the database admin??? Saved something and was able to retrive it What about attributes???? Lines, polygons, etc? VBA??? ARX?
- 6. The Reality… ACAD to Oracle is not easy No previous oracle experience at BOE ACAD map Oracle interface is not intuitive, does not have mechanism to maintain strict data schema, assure data integrity and network connectivity Costly $$$$ Learning curve for admin, GIS technicians, etc Difficult to Users Learning curve and established processes already in place become impediments to implementation by engineering line staff
- 7. Options? ACAD Map Queries Already in use Can link to databases SDE? Attributes??? Drivers for ACAD? Develop custom Apps VBA API not available ARX Maintenance Where is Autodesk going???? FDO vs OSE? 3 rd Party Apps
- 8. Decision to Use Munsys Off the shelf App for Oracle/ACAD integration Relatively simple schema for utility SF is combined system, Munsys has storm and sewer separate Maintains network integrety quite well but requires practice and training Spatial Data Manager has a lot of flexibility New to the “States” Willing to make a good deal Strong background in ACAD and GIS less so in engineering solutions
- 9. BOE-CCSF Phased Deployment of Oracle/Munsys Phase 1 – Data Loading, Training, Initial Use Phase 1: – Combined sanitary and storm system network connectivity and validation Data loaded: 1000 miles of pipe (27 000 links, 28 000 nodes) Servicing 153 000 parcels Sewer And City GIS Basemap Convert attribute data from SQL Server Change GIS/Engineering Process: Autodesk Map/Munsys- Train 5 editors, 30 Drafters and Engineers Automate shape file generation for other users Adapt Schema to facilitate new data storage/retrieval (Oracle) Use for GIS updates, corrections “ tease the drafters” Wait for management to catch up

- 26. BOE-CCSF Workflow Changes Before Managing separate spatial and attribute data Developing custom data capture and maintenance tools Creating SHP files from Map and SQL (6 hour process, difficult to batch) Limited access to data for engineers Various Data sources not in synch Unable to keep network connected when edited by several people at once
- 27. BOE-CCSF Workflow Changes Before Managing separate spatial and attribute data Developing custom data capture and maintenance tools Creating SHP files from Map and SQL (6 hour process, difficult to batch) Limited access to data for engineers Various Data sources not in synch Unable to keep network connected when edited by several people at once After Single data source for spatial and attribute data Off the shelf tools in Munsys provide 95% of the functionality Create SHP files in batch mode – time reduced to 3-5 minutes Free form access to current data for other applications Data sources all in once place Creation of a single connected network that can be continuously updated by Multiple BOE engineers directly
- 28. ROI Indicators Creation of SHP files from 6 hours to 3 minutes Creation of connected network which can be constantly improved In service from day 1 Data integrity improved (two sources to one) Productivity improvement with off the shelf tools (investment change from creating and maintaining tools to using tools) Convenience and ease of access to the current data greatly improved System architecture that enables integration into the enterprise – Phase 2
- 29. BOE-CCSF Future Integration Bring Mechanical section up to speed As-built viewer – Document Mgmt Hydraulic and hydrological modeling software integration – DHI-Mike Urban/ Wallingford Other data sources Space planning Facility BIM?
- 30. Lessons Learned Implement in phases Flexible goals and timelines Wait for engineering team to “catch up” Be clear but flexible about ways to integrate into Business processes Be cost effective but with knowledge that its an investment that might take a while to pay off Keep the dream alive
