Learn matlab to draw geographical map, line scatter bubble density map

1 To mark   text([lat lon],'balabala')

2 Figure scope geolimits([lat1 lat2],[lon1 lon2])

3 Specific picture

3.1 Line diagram geoplot   

If there are two points A(lat1 lon1) B（lat2 lon2）

geoplot([lat1 lat2 ],[lon1 lon2],'g-')  %g-  and plot equally Or draw the picture and then adjust

3.2 Scatter plot geoscatter

geoscatter（lat,lon,A,C,'^'） A For each marked area （ In square pounds ）   C For color   ^ （ triangle ） Scatter graph

2.  geobubble(text.lat,text.lon,text.part2)    use text Add ‘ . ’  Indicates the corresponding part , For notes on both sides

gb.SizeLegendTitle = 'Max Height';
gb.ColorLegendTitle = 'Cause'
