Geodetic Monument Viewer (new version)

Basic Navigation

Detailed instructions and Geodetic Layer definitions will be available soon.

Navigate to locations using zoom buttons in the upper left corner (or, if you are a mouse user, the mouse wheel). Mouse users may also hold the left button to pan the map.

Zoom directly to locations by using the search bar at the top of the map.  Use the dropdown for more search options.

Many layers are scale-dependent and will not appear until the map is zoomed to a specific scale.  Zoom in to display the default geodetic monument layer.

Display geodetic monument datasheets by first clicking on a geodetic monument symbol, using the arrow at the top of the popup window to scroll between multiple information boxes if necessary, and finally clicking on the Get Datasheet link at the bottom of the information box.

Display geodetic monuments by different datums/adjustmnets by choosing the relevant layer under the Layer List tool found on the tool bar at the bottom of the map.

Expand the Reference Layers grouping under the Layer List tool for access to many additional layers.

This map service should be compatible on most browsers and mobile devices.
