11.6.1 Base surface
The
Base surface
controls control the base surface being used for volume computations. This surface defines the
horizontal extents over which a volume is computed and the vertical base level to which all volumes are computed.
Surfaces must be prepared in external software. The web application accepts Carlson TIN files, or DXF surface
files. Uploaded DXF files are converted to TIN format for use onboard the FIX1.
The surface must be geo-referenced on the same coordinate system as that used to survey in the
Base Plate
Coordinates
(see section 5.4 above).
The Base surface may be derived from design files for the site, from a historic survey of the floor level or from a
new scan of the site. It is essential that the surface be as far as possible, a close representation of the survey of the
solid ground or structure underneath the stockpiles to be measured by the FiX1.

dialog appears. Select the appropriate
TIN or DXF surface file from your computer and click

.
The file is uploaded to the FiX1. This may take a few minutes depending on the size of the file. When it is
complete, the uploaded file appears in the
Base surface
drop down list.
