Survey Control Densification Program
In 1999, the Village's GIS Division began a program to collect utility locations throughout incorporated Lisle. Part of this project was the establishment of a network of vertical and horizontal survey control stations within the village to support engineering projects, future local surveys, and planimetric and thematic mapping. The survey control network is comprised of physical monuments represented in the State Plane Coordinate System.
Use of Survey Control Network Data
In 2006, the GIS Division updated the survey control network. This project included adding new monumentation and the recovery of disturbed monuments due to construction. Also, primary survey control monuments were measured again to meet National Geodetic Survey (NGS) specifications for 1st order horizontal control and 4th order class 1 control for ellipsoidal (vertical) height. Please see the NGS data below for further information.
