All maps used by Gds are from public domain sources, which means the style, quality and coverage can vary greatly by region.
Examples
Insert a map of New Zealand and plot three points given longitude and latitude values
/map/nzl?sz=120&p=175.28,-37.78,172.67,-43.5,174.78,-36.85&ptype=1&pmin=5
Insert the best map in order to plot three points given longitude and latitude values. The system looks at the points and typically draws the smallest available map that covers the points.
/map/best?sz=220&p=175.28,-37.78,172.67,-43.5,174.78,-36.85&ptype=1&pmin=5
