directory that is marked with that time step. This is useful to tick if the user is planning on
fusing the data multiple times and does not want the export to overwrite previous exports.
9.4.5.2 Export Options
This allows the User to specify export options. It is recommended to always only export
selected flight lines and compress the output to a Laz file.
The data can either be streamed to a single las/laz file or can be broken into individual flight
line las/laz files, even if a single file is export - the flight lines can be visualised from the point
source id field.
If the user requires a las file, then compress to LAZ can be unchecked. This will generate
uncompressed files, and should only be done for using software incompatible with laz files,
they are losslessly compressed - so no quality is lost for approximately 1/10th the file size.
9.4.5.3 Export Projections
This allows you to change the projections of the las/laz files to the prefered style and zone. This
will be matched by any base override coordinates.
9.4.5.4 Export Outputs
This is a check system for the files required in the exports folder. These are the deliverables of
the software. Checking Las File(s) will output a Las or Laz file depending on the export options
selected and the fusion setting chosen. Checking Map overlays output as per
.
Checking Combined Deci will output a decimated las/laz file in accordance to the decimation
setting chosen in the fusion tab, this takes more computational power that just streaming raw
data to a laz file.
9.4.5.5 Las / Laz file outputs
The main output are las or laz file outputs (laz are just losslessly compressed las files), version
1.4. The map projection as selected for export are included as WKT into the file.
The points fields are populated as follows:
PointSourceId
- Flight line number of the return.
UserData
- Stores the laser number (1-8) of the return.
ScanAngleRank
- Distance in metres of the lidar return.
Intensity
- The reflected signal strength of the lidar return.
Number of Returns, Return Number and GPS Time
are populated as per specifications.
9.4.5.6 Map Overlays
If map overlays are selected in the exports setting once the data is exported the map overlays
option will be present to show data information over the current maps and flight path.
