City of Palo Alto Department of Utilities

Only City-Owned utility in California that operates its own utilities including electric, fiber optic, natural gas, water, and wastewater

Summer 2009 – RFP – Geospatial Design and Management Solution Project (GDMSP)

Autodesk Topobase

Autodesk® Flagship GIS Application Client Web Administration

AutoCAD® frontend Oracle® Database Backend Fully Customizable

Why FME Desktop?

Needed to convert original data to Oracle Spatial (for use with Autodesk Topobase) AutoCAD dwg AutoCAD Map 3D Object Data Oracle Microsoft® Access SQL Server

Easy to Use Ridiculously Fast Fun

Readers and Writers

Readers (used for this project) Autodesk AutoCAD Map 3D Object Data Microsoft Access Oracle Spatial Object Oracle Non-spatial

Writers Oracle Spatial Object Oracle Non-spatial

AutoCAD Map 3D to Oracle Spatial

Challenge - All Text and Leaders had to be related to the feature that was being labeled

AutoCAD Map 3D to Oracle Spatial

Solution - NeighborFinder Transformer was used to store the parent feature entity handle for each text and leader feature

AutoCAD Map 3D to Oracle Spatial

Challenge – Gas Valves had object extended IDs that linked to data in a Microsoft Access MDB. We needed to translate the Access data in addition to the AutoCAD data.

AutoCAD Map 3D to Oracle Spatial

Solution 1 – AutoCAD Map 3D Object Data Reader extracted object data and extended entity data attributes

AutoCAD Map 3D to Oracle Spatial

Solution 2 – Joiner Transformer allowed us to connect to another DB and retrieve attributes based on the join ID attribute

Topobase Jobs

Long Transactions using Oracle Virtual Private Database Facilitates Approval Process Undo modifications Paper trail of feature edits Job promotion event

Challenge - Before adding data in Oracle, we needed to set a job by running an Oracle function select setjob(#) from dual. How do we do this in FME?

Topobase Jobs

Solution - We could run a SQL Statement in FME to set the job before translation:

Data Auditing and Cleansing

Challenge Required to do several rounds of data

auditing and cleansing. Did not want to use the live CPAU server. Wanted to do the work in our office. Wanted to copy the data over to their Oracle

server. Could not export and import schemas since

their database was live.

Data Auditing and Cleansing

Solution – Used FME to copy data from one Oracle server or instance to another (over a VPN connection nonetheless!)

Thank You!
