App similar to Star or sky Tracker

Hi All,

I would like to develop an app like Star Tracker or sitemap, not exact but similar to this one at

However, i am not able find right package or some help for Ionic for such apps, I tried NPM library but it has not given any accurate results.

Gone through various APIs however nothing similar to that. I am able to find various websites but not an App resource which can be used with Ionic.

Can anyone help or guide me in right direction that would be great. It’s an interesting concept so just needs some help.

Thanks in advance.
