The Olivenhain Municipal Water District (District) contracted with Nobel Systems to perform GIS conversion of their water system from atlas maps. Also included as part of the project was the development of a GIS database maintenance and document management applications, scanning of as-built maps, and training on the developed applications. A unique feature of this particular project was the hosting of the District’s data on Nobel Systems’ servers. This set up allowed the District to access their data over the Internet from any location.



Project 1: GIS Conversion and Application Development
Copies of the source maps were used as the primary data source for this project. Nobel Systems reviewed these maps and all source materials for unclear or ambiguous features. Using Nobel Systems’ AutoCAD-based proprietary data capture methodology and system, water facilities data was captured. Unique ID numbers were assigned to each arc and node feature at the completion of data capture for a given tile. Easements were captured using COGO. The attribute data was exported into a text file, then linked to the AutoCAD graphics using a LISP program, and the arc and node ID’s that were in both the graphics and attribute files. The data was then converted to the final ArcInfo format specified by District. All as-builts were scanned and linked to the GIS using a bar code numbering system.

• Pilot area database
• Sewer system ArcInfo database
• Plots
• Database maintenance application
• GIS/document viewing application

Project 2: Geoviewer Online Installation
Nobel Systems has been hosting the data for the District on Nobel Systems’ server, and allowing the District to access the data using ArcIMS. Using this option saves the District thousands of dollars each month, since there is no additional cost for hardware and software or the need to hire GIS staff.
