Hi I've noticed some unexpected behaviour when using 'if then' Today, in osm, a polygon can have multiple 'land describing' tags ie landuse=grass & natural=wood or landuse=forest and natural=heath etc To ensure both get parsed I use the following: if (landuse=* & natural=*) then # parse natural ; use continue ; delete natural natural=wood {echotags "wood & transparency"}[0x1101c resolution 18 continue ] #50 # add more natural= # at end of list delete natural so it doesn't get plotted lower down natural=* {delete natural} # continue parsing landuse end This works well, however ... The following url contains one natural=wood and area=yes (sic) https://www.openstreetmap.org/export#map=17/50.69541/-3.53819 There is no mention of a landuse and yet this wood gets included asif it has a landuse= something tag Is this because of the area tag? r Nick -- Sent from: http://gis.19327.n8.nabble.com/Mkgmap-Development-f5324443.html
