Alexey-

Is there a means by which you would suggest reducing the noise in the photos? The images were taken with MAPIR Survey2 Cameras, and their website recommended the 70 % side and front overlap.

Do you have any ideas as to why, other than the overlap not being sufficient? I would assume 70% is fine, from everything I have read. Could it be something to do with the darkness of the TIFF images?

Hi Alexey-

We used an overlap of 70% for all imagery. As I mentioned, I was able to get an orthomosaic from some visible band imagery, but not for the multispectral data. Any further insights?

Agisoft Photoscan was successful in processing TIFF images for a RGB dataset, but has been consistently unsuccessful in aligning all photos of the data set with respect to NIR and Red images. I have done this process with and without reference data for my images.I will include a CSV for your reference in the link below.  I used MAPIR Survey 2 cameras and a 3DR Solo UAS to collect the imagery on a generally sunny day in upstate NY. The TIFFs were created using MAPIR's plugin for QGIS and have coordinate and altitude information in the properties. The multispectral imagery is required for calculating NDVI over willow crops.

Here is a link to My Data Set: https://drive.google.com/drive/folders/18nwRnepFrK6HFd1XZRiA2lSdLrCdWgzS?usp=sharing

Any assistance or advice you could give would be incredibly helpful. Thank you.
