1. Resolve GPS kinematic corrections for the aircraft position data using kinematic aircraft GPS (collected at 2HS) and static ground GPS (1Hz) data collected over geodetic controls.
POSPac MMS v. 5.4
POSGNSS v. 5.3
2. Develop a smooth best estimate trajectory (SBET) file that blends post-processed aircraft position with attitude data. Sensor heading, position, and attitude are calculated throughout the survey.
POSPac MMS v. 5.4
POSGNSS v. 5.3
3. Create an exterior orientation file (EO) for each photo image with omega, phi, and kappa.
POS-EO
POSPac MMS v. 5.4
POSGNSS v. 5.3
4. Convert Level 00 raw imagery data into geometrically corrected Level 02 image files. UltraMap 2.3.2
5. Apply radiometric adjustments to Level 02 image files to create Level 03 Pan-sharpened TIFFs.
UltraMap 2.3.2
6. Apply EO to photos, measure ground control points and perform aerial triangulation. Leica Photogrammetry Suite 2013
7. Import DEM, orthorectify and clip triangulated photos to the specified area of interest. Leica Photogrammetry Suite 2013
8. Mosaic orthorectified imagery, blending seams between individual photos and correcting for radiometric differences between photos.
Inpho v. 5.5
2013-05-31T00:00:00The horizontal accuracy of the data set is 0.24 meters. Image accuracy was measured by independent ground check points. Check points were identified on the LiDAR intensity images in areas of clear visibility. Once the points were identified in the intensity images the exact spot was identified in the orthophotography and the displacement was recorded for further statistical analysisRMSEm 0.24 mdatasetEPSG7.9.4210712500.000000 4956750.000000712500.000000 4958250.000000713250.000000 4958250.000000713250.000000 4956750.000000712875.000000 4957500.00000050000.150000100000.150000Band_18Band_28Band_38Band_48FalseFalseFalseFalseFalse20130531
