We do not plan to add support for GeoPDF and GeoTiff.

You can already use your PDF as an overlay.

Way 1:
Convert PDF to image (for example PNG), and use in this example:
http://infinity-code.com/atlas/online-m … ample.html
The only thing you need is a little bit to modify the script to limit the area of overlay.

Way 2:
Convert PDF to image (for example PNG), split the image into tiles (for example using MapTiler), and use in this example:
http://infinity-code.com/atlas/online-m … ample.html

Is there any way to import into infinity maps any of these ? GeoPDF, geospacial, geoTiff

I am hoping to display maps created in Avenza
eg open and display this map:
