How to Provide Model Real World Coordinates (RWC)?

This guide provides informational guidance on how to provide the correct information to synchronize the position of the Versatile device with the Versatile model and system.

Why We Need Real-World Coordinates (RWC)

Real-world coordinates are crucial for accurately integrating project data into Versatile’s system. By aligning your project with precise geospatial information, we can:

  1. Ensure Accurate Site Setup: RWC allows us to establish the project’s exact location, orientation, and scale, providing a reliable foundation for data visualization and analysis.
  2. Enable Precise Device Syncing: A clear reference between the model and real-world coordinates is necessary to accurately synchronize the Versatile device’s position with the model and system accurately. Misalignments or inaccuracies in the model's coordinate system can reduce the quality and reliability of insights provided by Versatile.
  3. Optimize Project Insights: Precise geospatial data enhances the accuracy of the insights and analytics generated, improving decision-making and accountability on-site.

 

Required Options for Delivering Real-World Coordinates Information

We require one of the following four options to ensure the accurate setup of your project:

1. BIM Model contains Projected Coordinate System 

 

  • U.S. projects: The BIM model provided contains State Projected Coordinates System (SPCS) with latitude, longitude, elevation, and true north angle 

 

  • International projects: The BIM model provided contains Projected Coordinates System (PCS) with latitude, longitude, elevation, and true north angle 

 

2. Survey Plan / Site Plan with Projected Coordinate System



  • Survey Plan (.dwg) that contains State Projected Coordinates System or Global geographic coordinate system (e.g., WGS84, GPS) with grid lines of the project.

 

  • Survey / Site Plan (.pdf) contains at least one grid intersection showing the Northing & Easting coordinates (Projected or WGS84) and indicates the angle to the true north.




3. To-Scale Project Plan with Reference to a Map
  •  A to-scale plan with grid lines of the project overlaid with Google Maps or another mapping system.

 

4. Coordinates table with Grid lines names and Projected Coordinates 
  • Coordinates table (.excel or .pdf) contains grid-lines intersections, names, and Coordinates values of Northing & Easting (Projected or WGS84) that align a grid contained in the model.

 

Important Notes:

  • Please provide the EPSG code for the coordinate system used, along with the coordinates.*

 

  • If the required coordinate information is unavailable, we recommend reaching out to the VDC or method engineer for assistance. Should additional assistance be required, you can also contact the project surveyor as needed.

 

*EPSG Code - a unique identifier for a specific coordinate system, ensuring accurate geographic reference and proper data interpretation.



EXAMPLES:


Example 1:

Model with Coordinate System - model contains Projected
coordinates system with elevation and angle to true north. See Figures 1.1 and 1.2.

Example 2:

Survey Plan/ Floor Plan with Coordinate System - Survey plan (dwg
format) with project grid lines. Grid line intersection at A1 & M1 contains the
real-world coordinates. See Figure 2.1.
