Wonder if anyone can tell me what is going on here? I have a set of files that produce a grid, fixed points and a surface image as per the attached (fairly boring I'm sorry - image removed to keep the file size down) The output strangely has the north arrow pointing south (I am using 5.2.6 - however older datasets seem to process OK so far). The fixed points and the surface image are aligned almost perfectly, but the grid appears to be about 10m too far north relative to the fixed points and surface image. Perhaps my grid definition is somehow using a different co-ordinate system or the fixed points are been moved (in error?) by some loop closure routine? The displacement seems to be the same regardless of the std deviations following the point definitions. There are no survey legs, only fixed points. The grid is set by; grid-size 500 100 100 metres # coordinate grid The fixed points are set by; #btmleft centreline #Set Co-ordinate System and Entrances #------------------------------------ cs EPSG:27200 #NZ Map Grid 1949 #Recorded Entrance co-ordinates fix btmleft 2483000 8038000 000 0 0 0 #NZMG #Identified Survey Stations #-------------------------- station btmleft "btm left cnr of map" endcentreline #topright centreline #Set Co-ordinate System and Entrances #------------------------------------ cs EPSG:27200 #NZ Map Grid 1949 #Recorded Entrance co-ordinates fix topright 2486000 8042000 000 0 0 0 #NZMG #Identified Survey Stations #-------------------------- station topright "top right cnr of map" endcentreline The surface image is set by; surface cs EPSG:27200 #NZ Map Grid 1949 bitmap "./Parapara South GIS Plan geo98 contour 10000 A2.jpg" \ [349 344 2483000 8038000 2050 2602 2486000 8042000] endsurface
