Hi Shaun, sorry, now I can't debug your values - but as I remember it is not easy.
I am calculating with this ugly SQL function - for every country. * https://github.com/taginfo/dockerized-taginfo/blob/master/setup/setup_xtaginfo_admin.sql#L42 and my result for GB - this. https://github.com/ImreSamu/dockerized-taginfo/blob/sotm2018/service/eu/gb/taginfo-config.json - but this is smaller than yours ( ~ 2-3 day online: http://207.180.196.156:20142/keys/highway#map ) included : https://en.wikipedia.org/wiki/Rockall - so it is strange .. ------- and calling with your coordinate - my result. =============== osm=# select get_xtaginfo('gb', -12.35,2.98, 49.47, 61.2) ; NOTICE: OK R# = gb, 18 , 279.000 , 216.000 ,0.170 ,0.270 get_xtaginfo ------------------------------------- {279,216,-12.35,3.150,49.47,61.470} (1 row) ============== so the geneated image: 279 x 216 pixel and the coordinates= -12.35,3.150,49.47,61.470 but I can't test ..
