In April of 2002 a LIDAR (LIght Detection And Ranging) survey was taken of Lake County, Illinois. This survey produced 2 foot contour lines with sufficient detail to satisfy National Map Accuracy Standards (NMAS) for a 1 inch = 100 feet product. The topographic map gallery lets you view and download these topographic maps at no charge. You can find a topographic map by street address, Property Index Number (PIN) or map page number. The PIN for a tax parcel will be found on its tax bill or assessment notice. Once a map is displayed, using Adobe Acrobat, you can:
- Zoom in and out
- View different parts of the map by panning
- Print what you see
- Cut and paste portions of the map into a word processing document
- Navigate to adjacent map pages by clicking on directional icons
- Exit to begin another search

The black and white 2 foot contour map product displays the 2002 aerial photography with the LIDAR derived 2 foot contours for a specified quarter section at 1 inch = 200 feet or a specified quarter-quarter section at 1 inch = 100 feet.
The color countywide Surface Topography Map product was made possible by the LIDAR data. It gives a unique perspective not formerly possible owing to the absence of a high quality elevation base for the county. Elevation is shown as a range of colors with shading to simulate shadows. Roads and place names are subtly included to orient the viewer.

Two Foot Contour 1 inch = 100 feet cover 1/8 of a square mile.
