This new Lewis County WebMap combines the features of the previous PATSMap & CARLMap into one application, replacing both.

With this new program, we have added 2ft contours created from various LiDAR & photogrammetric surveys where available.

Most data layers can turned on/off at any time, though some are scale dependent and will require you to zoom-in before they turn on.

The map now will automatically redraw when any layers' visibility is changed.
