Yes, OK. So is my problem really just with the UTM map
projection? Could be, I suppose. I did, at one point,
fool around with other projections, but that may have
been in one of my totally confused periods. These do
seem to work properly.

Thanks, Liam.

Cheers,

David

The following works pretty much the way you would expect it to:

;- Lambert Azimuthal Equal Area (Great Lakes)
map = map_proj_init(111, center_lat=45, $
center_lon=-85, limit=[40, -95, 50, -75])

;- Default position
window, /free
plot, map.uv_box[[0, 2]], map.uv_box[[1, 3]], $
xstyle=5, ystyle=5, /nodata
gshhs_plot, 'gshhs_i.b', level=2, map=map, noclip=0
map_grid, /label, /box, map=map

;- Default position (isotropic)
window, /free
plot, map.uv_box[[0, 2]], map.uv_box[[1, 3]], $
xstyle=5, ystyle=5, /nodata, /isotropic
gshhs_plot, 'gshhs_i.b', level=2, map=map, noclip=0
map_grid, /label, /box, map=map

;- Position specified
window, /free
plot, map.uv_box[[0, 2]], map.uv_box[[1, 3]], $
xstyle=5, ystyle=5, /nodata, $
position=[0.1, 0.1, 0.6, 0.6]
gshhs_plot, 'gshhs_i.b', level=2, map=map, noclip=0
map_grid, /label, /box, map=map

;- Position specified (isotropic)
window, /free
plot, map.uv_box[[0, 2]], map.uv_box[[1, 3]], $
xstyle=5, ystyle=5, /nodata, $
position=[0.1, 0.1, 0.6, 0.6], /isotropic
gshhs_plot, 'gshhs_i.b', level=2, map=map, noclip=0
map_grid, /label, /box, map=map
