Relationship with DuPage County... • DuPage County has their own G.I.S. Department • Provide data to all their municipalities for a fee. • Parcels, Center Line, topos, orthophotos, real estate files, and much more is all delivered • Fee was recently waived with a data exchange agreement.
Need for Utility Information in our new GIS • As of 1995 all utility information in plat books as mylar (paper) format. • Original book dates as far back as mid- 1960’s , with updates to 1989. • Village purchases AutoCAD Map GIS software • Need for Mylar Utilities to be converted into digital (AutoCAD)format
Village Outsources Utility Data Conversion • Contractor sends mylars to Russia to be digitzed • Village now has digital CAD files of Stormwater, Wastewater & Water Distribution systems • Quality assurance went overlooked • Some areas missing, layers combined, many features duplicated
Using GPS to collect data • Utilities are in CAD format- No data Intelligence • Lights, Trees, Signs are non existent. • With GPS you can collect spatial data accurately. • You can also add non-spatial data on the fly Photo courtesy of www.trimble.com

Summary • GIS is expensive. • Upper Management must realize big picture- Show Upper management how the benefits outweigh the costs in the long term. • Utilize existing employees that have some skills to collect data and have knowledge of the systems. • Don’t re-invent the wheel. • Collect data any way you can. • Avoid spending money on consultants to plan if you cannot follow through • Dan Price - priced@villageoflombard.org 630-620-5740
