Data Collected : 06/18/21
Desired output for LAS/LAZ: NAD 83 (2011) 2010.000 UTM 14 North Meters, NAVD88 - Geoid18
: NAD 83 (2011) 2010.000 UTM 14 North Meters
NAD 83 is the North American Datum of 1983 and is and stable relative to the North American tectonic plate.
NAD 83 =
(2011) =
2010.000 =
UTM 14 North =
Meters = Units
: North American Vertical Datum of 1988 (NAVD88) – 18
Note: Orthometric vertical datum’s require user to select a geoid model.
For the United States, the GEOIDxx geoid models as been developed based on observations by NOAA’s National Geodetic Survey (NGS).
These geoid models (e.g., GEOID 99, GEOID 03, GEOID12, etc.) provide the geoid undulation parameter (geoid height), so that the ellipsoid height from the NAD 83 three dimensional datum can be directly converted to the NAVD 88 orthometric height.
Next, select the Horizontal coordinate system "NAD83(2011)/UTM zone 14N" (Datum and Map Projection) and NAVD88 (orthometric vertical datum) as the vertical coordinate system + GEOID18 (Geoid model)
LiDARMill may prompt the user to select the output coordinate system within the Spatial Fuser Pipeline. If it does not prompt the user, the Project CRS will be used.
Also select the desired Geoid18 geoid model.
In Inertial Explorer, select the datum "NAD83 (2011)" during the tightly coupled trajectory processing step
During , select "NAD83 (2011)" as the project datum and select "Metre" for the project units.
The project CRS should match the . You can verify the GCP CRS by clicking on the "GCP" tab within LiDARMill, and then clicking the button to the right of the GCP artifact, then click "Edit artifact"
In of a Navlab Pipeline, select the NAD83(2011) refined trajectory. Navlab will automatically specify the epoch as 2010.000
In of a Navlab Pipeline, select the output datum as NAD83(2011)
in SpatialExplorer, and click on the datum at the upper right to configure the datum as NAD83(2011) and manually input the epoch as "2010.000".
When into Spatial Explorer, Select the Horizontal CRS as "NAD83(2011) / UTM zone 14N" with units set to "metre" and select the Vertical CRS as "NAVD88 height" with units set to "metre".
During trajectory processing in Inertial explorer, as "NAD83(2011)" and the epoch as "2010.000".
In Inertial Explorer, select the datum "NAD83 (2011)" during the step
When into SpatialExplorer, input the trajectory epoch as "2010.000"
When , select the Horizontal CRS as "NAD83(2011) / UTM zone 14N" with units set to "metre" and select the Vertical CRS as "NAVD88 height" with units set to "metre". Also select the desired Geoid18 geoid model.
