Custom Site Projection

Sites and surveys are sometimes in a specific site coordinate system to make measurements more accurate and comply with standards set for the sites.

The ROCK Cloud also allows you to specify your own coordinate system. This is useful for site-specific reference systems based on a location unique to your site. This is done by:

  1. Selecting 'Custom Site Projection' for the Horizontal Reprojection, and
  2. Creating three or more Ground Control Points where the GCP specifies the X, Y, Z points in a well known projection using an EPSG code and then specifies the equivalent coordinate in the local custom projection within the custom x, custom y, and custom z fields.

The ROCK cloud will use this information to create a 4x4 transformational matrix to transform your data.
