I am new to gmt. I created a global map and I am trying to add a image of a satellite to the globe. Can someone tell me what I am doing incorrectly. The map gets created but the satellite does not appear on the globe. If run separate the the satellite does get created.
gmt pscoast -Rg -JG45/-20/6i -Bag -Dc -Gforestgreen -Sblue3 -P > ~/Desktop/globe.ps
gmt psimage ~/sat.png -Dg45/-20+w1i -Rg -JG >> ~/Desktop/globe.ps
gmt psconvert -A+s4c -Tg ~/globe.ps
