Plot map of small region and extract data (coordinates for that region)

Added by KRISHNA PAL 10 months ago

I am a new user to GMT and also new to the field of the Mapping and analyzing earth data.
I wanted to plot a region and obtain the values of the coordinates for that region.
I used the command

-JA49.39/-1.83/4i -R49.30/49.48/-2.18/-1.48 -Bg0.6/g0.6:"MAP": -Df -G187/142/46 -S109/202/255 >
But this giving the map of the complete globe.
Also, can you tell me the command how to obtain data(coordinates) for this region?
Thank you.
