The
Base surface
drop down list displays all surface files that have been uploaded to the FiX1. Select a
surface file from the list.
The surface file which has been selected and is currently displayed is the
Base surface
currently in use.
This will be used for volumetric computations on subsequent new or reprocessed scans.

11.6.2 Areas of measurement
By default, one volume is returned each time a FiX1 (or a hub-and-spoke group) completes a scan.
To separate the scanned area into separate regions, use the
Areas of measurement
function. A volume is
computed independently for each region.
The regions must be delineated by polylines. A single file can hold any number of polylines. The polyline must be
prepared in external software. The web application currently accepts just Carlson PLN files.
The polyline 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 polylines may be derived from design files for the site, from a dedicated survey, or from FiX1 data. The height
(Z) value of each point along the polyline is ignored for the purposes of the establishment of the regions.
Each polyline in the file must have at least three vertexes. If the polyline is not closed, the FiX1 will close it by
automatically.
Name each polyline after the region that it encloses.
To use a PLN file, hit the
Upload
button and select the appropriate file.
All named regions within the PLN file are displayed
In the
Scan list
, a volume is reported for each region in the PLN file.
11.6.3 Volume calculation parameters
•
Cells on X Axis / Cells on Y Axis
: The FiX1 generates a grid over the base surface. As the scan
progresses, each scanned point within the limits of the base surface is assigned to one of the grid cells.
The gridded data is then used to create a surface which in turn is used to compute a volume.
