General / Large GeoTIFF hangs Windows Explorer [solved]
« on: January 04, 2018, 08:06:24 PM »

I've been having this issue for a couple years and never found a solution. I've scoured the interwebs on several occasions and did find a bunch of people having the same issues, with TIFF files, but all of them are old cases and only involve people on Windows Vista and Windows 7, for which Microsoft released a patch, but that does not affect Windows 10.

I'm certain some of you have seen this so I'm hopeful someone has a suggestion.

Large GeoTIFF files tend to hang/freeze Windows explorer. Like if you browse to a folder with TIFF images, just simply clicking your mouse (single click) to select the TIFF, it hangs Explorer, becomes unresponsive for quite a while. Trying to select a group of them with dragging a box around them, hangs explorer. Trying to drag them to another location, say to copy them somewhere else, hangs explorer, basically ANY interaction with it hangs explorer.

By "large" TIFF files I mean under 4 GB, I use the auto-split in Agisoft at the export stage and it breaks them down in to sections of varying sizes, typically 500 MB to 2 GB because Windows does not like greater than 4.5 GB TIFF. Well it seems to not like smaller ones either. These are orthomosaics from UAV mapping.

I'm actually thinking this is a main reason I have lag issues scrolling in/out in Global Mapper software, which I am currently evaluating before purchase. Loading these same TIFF images into that software provides a non-smooth experience when zooming in and out. Might be associated with how Windows is dealing with the files in the background. Internet research points to paging file settings (which I've tried), how Windows is allocating memory when interacting with the files. But all of this is relating to Windows Vista, and no patch or user cases I found of people discussing Windows 10.

Any thoughts?

Thanks in advance!

Bug Reports / Photoscan 1.3.3 & 1.3.4 problems
« on: December 08, 2017, 07:23:06 AM »
Ok I'm 90% sure these problems did NOT exist in 1.3.2, but only in 1.3.4 and 1.3.3. However, unfortunately, I deleted my 1.3.2 installer and I can't find a replacement that isn't a torrent hack or something that I don't trust, so I can't downgrade and go back and check.

I ran 1.3.2 for a long time because when I installed a newer version I ran into this issue where I process the photos (align) and point cloud in WGS84, then process the ortho/DEM in UTM/3TM (UAV data) and I can't zoom in on or even view the ortho or DEM. I can double click the point cloud, zoom, pivot, fly around, no issues. But the DEM or Ortho if I double click, nothing is there on the display. If I double click the DEM and the screen is blank, also so is the menu bar, it literally disappears. Screenshot attached. I highlighted in the screenshot the totally blank toolbar. I tried re-processing the DEM/ortho in WGS84 and it's still blank. So I don't think it's a UTM/CSRS projection issue. I think it's a version issue.

It's funny because the toolbar completely goes blank, only if I double click a DEM or ortho. At that point the software is unresponsive totally to mouse scrolling (zooming) and clicking on the toolbar, the only thing to bring back software response and the visible toolbar is to double click back on the dense cloud, then I have full zoom/pivot and the tool bar. Other than that the software is unresponsive.

I also investigated the forums and searched, and found some topics that somewhat resembled my issue (though not exactly the problem) and the solution was to update drivers or run the "-- opengl angle" on the exe and that didn't seem to help. Drivers are updated, etc.

I know for a fact that I tested this before. I have 2 hard drives on my laptop, 2 separate installs of Windows 10. One was running v1.3.2, other was upgraded to 1.3.4. If I opened the same project in 1.3.2, no issues. If i opened in 1.3.4 on other hard drive, I could not see or zoom on the ortho or DEM. I had since, and some point, upgraded to 1.3.3, and now I dont have 1.3.2 to test, and still have the same issues. For a few months I was avoiding updating due to the issue I saw. But now we've sold some more UAVs and have customers downloading trial Photoscan software and I'm still having issues. So are they.

I am the pilot and demo person for a large UAV reseller and soon to be Photoscan reseller, hoping for a fix soon. I had zero issues for almost 3 years, now the software is unusable.
