[OSM-talk-ie] Talk-ie Digest, Vol 70, Issue 9

Hi everyone,

A basic question but grateful for any assistance!  I've followed the flow
chart on the wiki, and identified the map I wanted to digitise in mapcraft,
where the owner is haribo. The map is http://mapwarper.net/maps/1924
also IRL-GSGS-3906-17-17-NE-Cloghjordan.tif.


When I follow the link in mapwarper I can see that the map has been
cropped, georeferenced with 30 green and blue points and aligns to osm. The
history shows it was last worked on in December 2014.

My understanding is that because the work has been completed in mapwarper,
I can go to josm and just start tracing townland boundaries if these
haven't been done already. What I'm not sure about is how I add the map
layer into josm and I couldn't find the instructions for this in the
videos.  I'm sure it's a simple step but would be grateful if someone could
let me know how do it correctly or point me in the direction of the
instructions.  I have installed the townland boundary settings in josm
already so should be good to go after that.

Many thanks,

Rachel
