<p>Hi Jose,</p>

<p>What do you mean "be geo-referenced"? What I'm thinking is to use these tools to convert a 360 panorama picture, such as <a href="https://upload.wikimedia.org/wikipedia/commons/3/35/Space_Needle_360_Panorama.jpg" id="LPlnk119911" title="https://upload.wikimedia.org/wikipedia/commons/3/35/Space_Needle_360_Panorama.jpg

which is an equidistant cylindrical projection, to other type of projection, which keeps same quality but with smaller size. Thus I can save some storage spaces. In this case, these 360 picture doesn't have any geo-referenced data. Can I still use these tools? </p>
