How to facilitate precise measurements using local grid conversions

In mining operations, local coordinate systems are often used to facilitate precise measurements and mapping within a specific area. However, when sharing data or collaborating with external parties, it becomes necessary to convert these local coordinates to a universally recognized coordinate system like EPSG (European Petroleum Survey Group). This ensures compatibility and consistency across different platforms and applications.

 To accomplish this, navigate to Survey Tab choose New to open the Conversion System Conversion Setup form. Choose Local and create a new formset. This method necessitates inputting two known corresponding points in both the local grid and the EPSG system. The conversion setup form is accessible across various interfaces including Convert (File), Convert (Wireframe), Image form, GIS form, and Grid Surface form.

It is a good practice to verify the accuracy of the transformed coordinates against known reference points to ensure alignment with project requirements.

In addition to the 2-point local conversion method, users have the option of utilizing the Plane Grid Conversion method, which offers more advanced capabilities for converting local grids within our software. This method is particularly beneficial in scenarios where adjustments such as scale changes or rotations are required, or when dealing with three or more known points. To access this tool, users should navigate to the Survey tab and locate it within the Coordinate Systems group. There are two primary scenarios for utilizing this method: in the first scenario, multiple known points are available for calibration, ensuring higher accuracy in the conversion process; in the second scenario, a simple bearing correction is applied to align the local grid with the desired orientation. By leveraging the Plane Grid Conversion tool, users can address more complex conversion needs within their projects, ensuring precise and accurate results.
