All panoramas that you upload to your account are reviewed before being published on the 360Cities.net site.
- JPEG or 8-bit TIFF format with no layers
- Only standard ASCII characters in the filename (examples of characters not allowed: ü, á, ě, etc.)
- Your panoramas must be 360º - the left side of your panorama must match with the right side of your panorama so the viewer can enjoy a fully immersive experience of looking all around without any visible seams
- The height of your panorama must be smaller than the width (vertical panoramas are not accepted)
Panoramas that don't meet the technical requirements will fail to upload.
To upload a fully spherical panorama, make sure the aspect ratio of your panorama in pixel width and height is 2:1. Example sizes of panoramas that will be treated as spherical: 6000x3000, 10000x5000, 8422x4211.
This includes promotion on the map, in the search results, nearby panoramas and various other places
If your panoramas are not selected for public promotion, you can still view them from your account and profile and you can share them without any limitations.
Are you waiting too long for your panorama to be reviewed?
We usually review all panoramas within days. If you think always wait too long, you might want to upgrade to a paid account and get a higher priority in the review queue (the higher the account the higher the priority you will get). We guarantee the review for all paid account panoramas within 7 days but usually this happens within 1-2 days.
The images you upload to 360Cities must have a minimum width of 6000 pixels to be selected for 360Cities and Google Earth. Exceptions are sometimes granted for good quality panoramas that are smaller. Panoramas smaller than this don't look good in fullscreen view. The images must NOT be enlarged because this reduces the quality of the image. With ALL dSLR cameras, it is possible to make a panorama that is 6000 pixels wide or larger. All of our panoramas load at the same speed - very fast! It doesn't matter if the original image is 6000 or 25000 pixels wide.
Tip: In case you're not already aware, we are using a multi-resolution tiling system to display the panos. This has two advantages. First, the pano will load much faster because it only needs to load the necessary tiles depending on the screensize and the part of the pano you're looking at first. Second, it allows you to zoom in to the original resolution of the panorama.
Images should be in JPEG or TIFF (8 bit) formats with no layers. TIFF files can have up to 65536 x 32768 resolution. We recommend that TIFF files be uploaded using FTP. JPEG files can have up to 30000 x 15000 resolution (which is the maximum size allowed by JPEG format). JPEG compression (quality) should be ideally 85-90% to ensure a good viewing experience.
