<div>Hi Everyone,</div>
<div> </div>
<div>I'm a software developer on a NASA contract, I'm working on a web based platform that pulls data from various providers in different coordinate systems, but not all my coordinates are earth based. I recently discovered proj4js which led me to you.</div>
</div>
<div> </div>
<div>Throughout your documentation there's a lot of "geo", but my data is a mix of "geo" and "helio" where my coordinates are relative to the sun, not the earth. Is there a way I could use proj to transform between earth-relative and sun-relative coordinates? I need to convert between a geocentric system and heliocentric system.</div></div></div>_______________________________________________<br>
