Thanks Kevin. The map is now in the atlas. Welcome as a contributor, it is much appreciated.

That linked area do get a bit small though, very hard to see. Maybe someone wants to make an intermediate map showing the surrounding reef area in more detail.

(This will be the last map I add for a couple of weeks)

Menina Island can now be found in the atlas. Thanks.

Finally in the atlas. Sorry for the delay.

Since those above didn't answer this, yes, this is how it works. You can make commercial maps out of the box with the standard license. and those maps can be utilizing any of the assets distributed with the program. Note that this is limited to publishing the maps you make with said assets commercially, you're not allowed to distribute the assets themselves. But please use the contact details provided by Sue above if you need official clarification, as most people here can only give you an unofficial answer.

To add a bit on to what Wyvern said, note that a lot of programs, especially those online browser-based ones, do not allow you access to download the artwork, they only make it available for use within their own application. I don't know the specifics of each of the programs you mention, but it isn't unreasonable to expect they are not downloadable in a legal way, but as Wyvern said, you need to research each of them (or maybe someone here who uses them can comment)
