1.One-Key P r o c e s s solution

It means theallparameters arerecorded intheLiDAR unit(Hardware) before Shipment,

andtheoffset(The position oftheAntenna totheposition ofLiDAR center, alsocalled

L e v e r A r m ) should befixed, thenitsupports One-Key P r o c e s s solution.

W h e n process thedata, o n l y addtheBase d a t a , P O S dataandLiDAR data(Camera folders

ifnecessary) notinput theparameter manually.

O f coursew e support One-Key P r o c e s s firmware for theclients, j u s t shareustheparameter

ofoffset (T h e clients usetheirdesigned mounting kit). S o m e type(shipped before N o v

2020) donotsupport One-Key P r o c e s s .

2.T h e gAirhawk software (4.8 version) iscombined trajectory processing andlidardata

processing together ingAirhawk software, itiso n l y for LiDAR S y s t e m w h i c h support

One-Key P r o c e s s solution.If donotsupport One-Key P r o c e s s solution, thetrajectory

processing should beinShuttle software separately.

P l e a s e install thegAirhawk software atD / E / F drive,notCdrive. Just incase itw o r k s in

abnormally (In Window 10system, u s e r ’ full control should begetifinstall o n Cdrive).

P l e a s e copyandpastethelicense.dat file tothelicense folder w h i c h locate inthecontent of

gAirhawk software.

Software Installation

The following figure isthecontent of g A i r h a w k software after installation successfully.

Before running thegAirhawk software, please makesurethefiles ( base data, POSdata, lidar data a n d

image folder ifrequired) a r e r e a d y .

Double click thegAirhawk iconon desktop, enter into theinterface of operation, a s following

1. C r e a t e aN e w Project

Click theFile icon, select N e w Project, enter into Create N e w Project interface, a s following

The file isnamed a s theTEST, thenclick theSaveicon( S a v e thefile with thesamelocation), enter into

L o a d data interface, a s following

There a r e GNSS B a s e bar, GNSS Rover bar, L i d a r File bar a n d I m g bar ( O n l y f o r thelidar systemwith

Camera)

Click theGNSS B a s e bar enter into GNSS B a s e interface, click theA d d bar toa d d thebase data, a s

following

Please input coordinates ifbase station coordinate required.

O r select Approximate Coordinates.

Click theGNSS Rover bar enter into GNSS Rover interface,

The Mode: thereisdrop-down menu, a s following 6-2

H e r e b y w e only select theGNSS differential data input f o r One-Key Process solution.

I f select The r e s u l t of outer GNSS input, only External GNSS Positioning results isavailable.

I f select POSinput, only POSfile path isavailable.

Click theA d d bar toa d d theGNSS Rover data, a s following

Click theL i d a r files bar enter into L i d a r files interface, click theA d d bar toa d d thelidar files, a s following

Click theI m g bar enter into I m g interface, click thechecking box toloadthePhotos Folder Path,a s

following (I f theLiDAR Systemiswith Camera)

I n this step,no need toloadEvent File Path( O n l y f o r One-Key Process solution)

Click theO K bar, finish Adding files, a s following (7-1)

A f t e r processing data a n d color point cloud output, ifmismatch happens(image a n d point cloud), please

delete thefirst photo from thebeginning whatever thenumber of trigger event a n d thephotos is.

2. Sett h e Coordinate System

Click theT o o l s bar, select Coordinate System, enter into Coordinate SystemConversion T o o l interface,

Click the ,Create new coordinate system, name a s WGS84 ( F o r example), click theO K icon, enter

into Coor Config interface,

There a r e Translate bar, Parameter bar a n d Ellipsoid bar

I n this step,only click theEllipsoid bar tosettheparameter, a s following,

click theO K bar tosavesetting.

I n this step,thelocal coordinate systemisavailable according totheclients requirements. I f not familiar

with setting, please check thelocal surveyor or consult engineers.

3. Sett h e Parameter

F O V : 30-150 ( According toRecommendation)

Distance : 5-200M (According toflight height)

Intensity: 0-255

Echo :T w o Echos ( T w o a n d Triple Echos a r e available)

Then select

POS(ENU, NED) ENU isdefault.

Coordinate systema n d F o r m a t (ENH, XYZ(ECEF), B L H ( D M S ) a n d B L H (Degree) a r e available

according totherequirement.

Output file

Output mode B y file or B y Strip

File format B y Output L a s or Output txt(According totheclients’ requirement)

Output color point clouds isselected only f o r theL i D A R systemwith Camera.

Eliminate uncolored points isselected means thepoint cloud without color will be eliminated.

I f select Output mode B y strip, thedata processing startautomatically (File partition, Kinematic

Differential GNSS), a s following

Then thetrajectory dialogue pop up ( O r Click theDivide Strip B a r ) , a s following

Enter into Manual Divide Strip interface, click theManual bar tochoose thestrips ( t h e client could choose

thestrips according torequirements, a n d only straight strips a r e chosen, removed radius parts)

Click thestrip from thestarttothee n d with leftclick (Mouse, not holding themouse)tofinish selecting

one strip, re-peat this steptoselect a l l thestrips y o u required. A s following

Click theApply bar, toSavesuccess.Then select O K bar tofinish Manual Divide Strip, a s following

I f y o u w a n t todelete thestrips or re-select thestrips, justselect thestrips on r i g h t (strip 1,2,3,4,5)

Then click theDelete Strip bar, itisdone a s following

Whenselect Strip Adjustment function, thestrips a r e only selected from N o r t h toSouth (South toNorth) or

from East toW e s t ( W e s t toEast), but not f u l l strips.

Click theSensor Configuration Parameter bar toview theparameter ( W h e n a d d thelidar a n d camera files),

thesystemwill r e a d theseparameter automatically. A s following

4. P o i n t C l o u d Calculation

Click theD a t a B a r , select Point Cloud Calculation tostarttoprocess thedata. The progress bar is

movement. A s following

Firstly itdoes theGNSS/INS integration process, thenprocess theL i D A R data.

During processing, forward & backward theroller of mouse tozoom in/out, thepoint clouds display strip

by strip.

I t could stopw h e n y o u click theStopCal/Read File bar ifrequired.

A f t e r processing, theprogress bar stops a n d display Calculation finished! . A s following (12-1)

Click theOK.

Check theL A S files inoriginal files.

Click theSavebar tosavethis project.

N o t e : The data displayed ing A i r h a w k is0.1% of total number of point clouds. Please review theL A S files

a n d do thenext procedure by 3rd
