New accessibility features for making aerial maps in MapKnitter

Map-making with your aerial photos is an important part of balloon or kite mapping. It's like making puzzles -- SOME people really love it and SOME people really don't!

MapKnitter -- now entering it's 9th year as a free and open source project hosted by Public Lab -- has slowly been getting upgrades and refinements that make it easier to use.

We've just posted an update that made MapKnitter more accessible, with new differently-shaped handle icons that also work on tablets, where map-making can be more collaborative. See it in action in the GIF above.

We also made the handles larger, which makes it easier to use on a tablet -- iPads make for a great way to get a group together and stitch a map in a group.

Give it a try at!

...or if you're working on your own mapping projects and want to use just the distortion component, check out our stand-alone library, Leaflet Distortable Image:

**Update **I also wanted to highlight that 2 different first-time contributors helped make this latest version possible!

Thanks to Nana Adjedu and Jason for their help in completing this update!

Yes, and we should show tooltips for them - could you open an issue for that?

R - toggle rotate/distort L - lock T - transparent O - outline (pretty similar to transparent)

I think that's it?
