So, I downloaded 70+ images from the nationalmap.gov website. Now, I don't want to add each one of these individually so I select the multiple files when I add the images and they look odd, almost chess board like.
If I add them one at a time, they don't have the checkered appearnce. Any idea on how to add them all at the same time and have them display correctly?
Solved! Go to Solution.
I have had this happen from time to time. Seems to be a glitch. The way that I fixed it was to go into the Options, Select 3D Generation, and change the Generator Threads count. I changed mine to 10 and had the issues with the images. Then changed it to 4, restarted the program and the images were fine.
Do your images have an alpha channel? Are your image tiles seamless or do they overlap a bit?
If you can provide a 3x3 tiles sample dataset I can have a deeper look into this.
The images are just GeoTIF files that I downloaded from nationalmap.gov. I'll see if I can get a tile group together for you. Not sure how big they will be but I'll do my best.
I tried editing the Generator Threads as suggested by Todd with no success.
So, I got the nine images showing the issue and here is what they look like in the model:
And this is how they look when I bring them into MAP 3D
I have the files in the zip file but it's almost 1 gig. I'll contact you via e-mail about getting the files to you.
Reporting back to the forum:
The provided images have 4 color channels: red, green, blue, and a 4th one, which looks either like a near infrared or like a gray-scale version of the RGB channels.
In the default settings, AIM assumes to use RGB + alpha mask for a 4 channel image, which is not appropriate in this case, since the 4th channel is definitely not an alpha channel; so you have several options here to setup the import correctly:
