Required formats for single PVOL images

Filename for single PVOL images

A specific filename format is required to have the single images stored in the PVOL database. Using this format, there is no need to fill in by hand any field in the database, because this is done automatically. An explanation of the filename structure and each identifier is given below. To see the difference between single PVOL images and multiple IOPW images, take a look at this page.

Filename for ANIMATIONS

If you want to upload animations stored in AVI, GIF or MPEG formats, you should follow this basic filename rules:

Filename for multiple IOPW images

We do not provide a filename structure for multiple IOPW images. As PVOL images are added to both IOPW and PVOL databases, we strongly encourage observers to send us single images with the PVOL filename structure. Remember that files with more than one planetary image are only added to the IOPW database and not to the advanced PVOL database.
