Paver Saver is a system which allows utility companies, the Kentucky Transportation Cabinet, and county and city public works departments to share information about their work schedules and locations. Paver Saver aims to prevent newly paved roads from being torn up to repair a problem, and then a month later, torn up again in the same spot by a different agency to fix another problem. The system finds where work schedules and project locations overlap and then notifies these organizations in advance so that they can potentially coordinate their work and save time, money and aggravation while keeping the road in good repair. It has already saved significant sums of money for participants in the short time it has been available. The Paver Saver application is a great example of how geographic data serves as the backbone of a collaborative solution that saves time, money, and resources.

Q: Where does the GIS data come from?

GIS data comes from many sources. Many base data layers such as roads, buildings, streams, etc., are obtained from aerial photography and photogrammetric processes. Other data layers such as city boundaries, zoning, voting precincts, or property lines are gathered from legal descriptions, surveys, and other authoritative data sources.

Q: Why not just use Google Maps?

Google Maps is a great tool for getting directions from one location to another, for creating an overall view of an area, and for visualizing the world through an on-ground perspective like ‘Street View’. However, Google’s data is private and proprietary, can change frequently, and is updated only at the discretion of Google. No background information about the data source (metadata) is provided publicly. It is unknown whether the photos are ortho-corrected (positionally accurate); and much of their photography is flown during the summer when trees are covered with leaves. LINK-GIS prefers “leaf-off” photography because it allows a clearer view of ground conditions, which is extremely important in land planning decisions. Finally, the data in Google is often copyrighted, raising legal issues and possible restrictions on its use.
