Cassandra, We have had very few cases of stripes in thermal reflectance maps and they were due to the NUC of the camera. The NUC effect can cause issues with the calibration because the same featur...

@HydroLab The parameters of the camera might be incorrect. You will need to verify the parameters by looking at the image properties editor and the manufacturer specs. The main parameters to verify...

Giorgi, Actually they are not invalid data, they will have value in each pixel. It just means there was less overlap in those areas, due to which one matching keypoint has been found in a very few ...

Hi Giorgi, 1. That would be the correct way of processing. However, if you want very accurate radiometric correction, you can also process each flight dataset separately with the target for that fl...

@Hydrolab, I just need the quality report and the p4d file for the final project. The easiest way to find the quality report: The p4d file will be there in somewhere with p4d as the format exten...

@Kang, if the images have 3 bands that means the format is jpeg not rjpeg. Rjpeg will be grayscale (though both joeg and rjpeg have the same extension, jpeg). For jpeg you will not get temperature ...

Giorgi, that you cannot because it is reading from the EXIF. Most of the times, if the camera is in the database, it will read from the database (and will have that cylindrical icon). If it is bein...

@Hydro lab, Can you send us your merged quality report and p4d file? You can upload in google drive and send us the link here or you could also write us a support ticket.

@Kang, If the images are rjpeg, the temperature values will be absolute, you do not need any conversion formula. Are you getting values outside your expected range?
