Unable to open a Tiff Created by Drone2Map

[JasonSchilling1]

I merged 731 photos into an orthophotomosaic, DTM and DSM. I was able to open the DTM, but cannot open the DSM or orthophotomosaic, trying various programs (microsoft office 2010, fast picture viewer pro, or adobe acrobat pro). My end goal is to convert the TIFF to a PDF, but adobe can't open the TIFF to begin the conversion process. Has anyone had this problem and found a solution?

The file size of image might just be too big.  Have you tried opening it in ArcGIS or other GIS package?

[XanderBakker]

You should be able to open it in ArcMap or ArcGIS Pro and convert to PDF as FC Basson mentioned. Do reconsider the resolution of your TIFF if the ultimate goal is to create a PDF (what resolution are you planning to apply for the creation of the PDF?). You could also use Resample—Help | ArcGIS Desktop or Aggregate—Help | ArcGIS Desktop to reduce the size of the data.
