Survey Control Points

Survey Control Data

Survey coordinate data provides a real-world context for the model and is used to describe locations on the surface of the earth. The survey coordinate system is synonymous with the following terms used by common software applications:

global coordinates
GIS coordinates
grid coordinates
surveyor coordinates
projection coordinates
state plane
shared coordinates

Importing survey control data

Survey data or "control points" can be imported using a CSV (Comma delimited) text file.

The file may contain header information in line 1
The units for the location data should be provided by the surveyor and will be entered at the time on file import
The data fields must be provided as whole numbers and configured in the following format:

[ID],[X position],[Y position],[Z position]

[ID],[Northing],[Easting],[Elevation]

A valid survey control CSV file will look like this:

NAME,X( ft ),Y( ft ),Z( ft ),DESC,LAYER

A,1961661.337,561876.397,102.339

B,1961624.025,561905.335,102.331

C,1961601.218,561924.732,102.292

D,1961591.915,561948.083,102.217

E,1961573.979,561969.853,102.223

Maximum distance from the internal origin

To ensure accuracy of the model, importing data with coordinates greater than 3 kilometers or 1.8 miles from the internal origin will automatically create a Project Coordinate system with the Project Base Point as it's origin. This transform is visible and can be edited using the cloud engine's Project Base Point.
