Hi,
I am trying to plot tasmania coastline on a map. I am trying to plot variable ctt with lonxlat in southern hemisphere.
I have been doing this:
pcolor(lon, lat, ctt);hold on
shading flat
load coastlines
axesm('eqaconic','MapLatLimit',[-57 -43],'MapLonLimit',[130 160])
plotm(coastlat,coastlon)
However, this is not working. I want to show the coastline with map on top.
Thanks.

To plot the coastlines, the map needs to be created first. This can be done by calling axesm first, and then plotting using pcolorm and geoshow:
load coastlines
axesm("eqaconic","MapLatLimit",[-57 -43],"MapLonLimit",[130 160])
pcolorm(lat,lon,ctt)
geoshow(coastlat,coastlon)
Alternatively, the array ‘ctt’ can be plotted using geoshow instead of pcolorm:
geoshow(lat,lon,ctt,"DisplayType","surface")

ok, is it possible to improve the spatial resolution of the Coastlines data base ?
