Astrolabe is an embeddable library for placing icons on the Minimap, and on World Maps. Icons that are placed on the Minimap using Astrolabe are placed in a special buffer and their positions are continuously updated for player movement, based on the world map coordinates provided when the icon was initially placed. Icons remain in this buffer until they are removed.

Astrolabe also provides functions to compute the in-game distance between two points and translate a point from one zoom level of the map another.

    Question: does the full documentation of the API still exists somewhere? The link above no longer works.

    There is an strange error, the WorldMapSize dont include data for the garrison if you do a fresh start of the client and login, if you logout a character and relogin or do a /reload it contains the data.

    Without digging deeper in it in the Astrolabe code, I would maybe guess an game side problem and maybe the solution would be to hardcode it like some other zones?

    I've been in touch with Esamynn about this.

    While I have an ugly solution to the problem that I have implemented for WoWPro , Esamynn and I have not come up with a permanent solution.

    You could just download WoWPro, enable only the base addon, and these errors should go away until Esamynn comes up with something better.

    Astrolabe seems to be breaking TomTom when entering the level 2 mine on my garrison.

    I also hope this gets updated on zone names so Archy can get working correctly with the TomTom integration.

    I'm sorry, but since an official version of TomTom with 99% of all my fixes was released, I stopped supporting that version.

    Please go to and download the latest!

    any chance on updating since Archy - Archaeology Assistant addon has problems with tom-tom? Thanks for the great work!
