U-SMART - (USACE Survey Monument Archival and Retrieval Tool)

Introduction

The U.S. Army Corps of Engineers (USACE) utilizes survey markers/monuments, known as Control Points, across the United States (US), to monitor and measure the condition of the land related to water levels and its effect on projects including those in the Corps Project Notebook (CPN). These control points provide geospatial positioning, elevation, and other important information that are used for consistency across planning, engineering, design, and operations and maintenance of a project and allow it to be accurately georeferenced to the National Spatial Reference System (NSRS).  This activity is critical to maintaining an understanding of the relationship between the various geodetic, tidal, and water level datums.

Objective

The main purpose of U-SMART is to provide a web based centralized system for USACE and Army surveyors to manage and view survey monuments, to include Control Point data and boundary monuments, and make sure that the latest values for these control points are current and up-to-date, relative to the NSRS, for the associated project.  U-SMART allows each individual district to manage their own control point data so others within the district can access it.

Benefits

• Common Source for all Project Survey Control – Share across District functions (all using same) 

• Current and up-to-date survey control, relative to the NSRS (National Networks)  

• Survey control can be associated to a project for easy retrieval  

• Links to existing NSRS Control  

• Links to water level gauges (USACE, NOAA, and USGS) 

• Versioning For Superseded Control 

• Data submission via web interface 

• Map interface to search, select, and export control points 

• Open to public (read only) 

Updates and Modernization 

U-SMART was recently updated to include the following enhancements: 

• Offline Control Point input/modifications 

• Enhanced Mapping, Display, Data Export Tools 

• SDSFIE Compliant Database 

• One page editing 

• Input in Geodetic or State Plane or UTM 

• Cloud based platform
