... Templot server as a "Templot map" entirely separate from OSM. In a conventional slippy map the tiles are bitmaps, but I'm thinking the Templot tiles could be EMF metafiles, which could be zoomed, printed, and used as construction templates in the usual way. Possibly we don't need any of the original OSM map detail at all, and can simply use the OSM functions to provide the geo-referencing and conversions. On the NLS historic maps it is possible to use OSM as the cross-fade background layer: 2_250417_280000000.png see: http://maps.nls.uk/geo/explore/print/#zoom=18&lat=52.37478&lon=-2.30360&layers=168&b =7 which could be used now in the current maps function in Templot to create the templates. (notice the mismatch in the OS historic mapping from the OSM data, derived from modern aerial imagery) cheers, Martin. posted: 26 Jul 2020 00:18 from: ikcdab Martin Wynne wrote: Rob Manchester wrote: Are you thinking it ...
