The Government-Standard SEMMS provides powerful software tools for importing, managing, querying, and exporting survey monumentation data using user-friendly alphanumeric interfaces.

Our SEMMS Viewer, SEMMSView, provides a graphic window into the SEMMS monumentation database. Regardless of the original coordinate system used for inputting the monuments into the SEMMS database, they can be displayed in their correct geographic location in the coordinate system of any displayed viewer file. For example, monuments put into SEMMS in UTM zones 15 and 16 in NAD 83, can be correctly displayed on a viewer file in State Plane NAD 27. Geodetic conversions and coordinate calculations are provided by integral Government-Standard CORPSCON source code software. Only those monuments within the viewing window are displayed and are shown in the list of monuments. Additional search criteria can be defined for monument discriminator, quality, type, vertical accuracy, vertical origin, horizontal accuracy, and owner. Wildcard queries based upon monument name are also allowed.

Monuments satisfying the search criteria are shown in the list of monuments and are graphically shown on the view using Corps of Engineers standard monumentation symbology for 1D, 2D, and 3D monuments. Monuments may be selected from either the graphic view, or from the list. If a monument is selected from the graphic view, its position in the list is highlighted. The same is true the other way around. When a monument is selected, it's details are shown in the text box at the bottom of the interface.
