MeteoInfoLab脚本示例：在地图上添加点、线、多边形

MeteoInfo

利用geoshow()函数可以在地图上添加自定义点、线和多边形。

脚本程序：

1. axesm(tickfontsize=12)
   
2. lworld = shaperead('D:/Temp/map/country1.shp')
   
3. geoshow(lworld, edgecolor='k', facecolor='g')
   
4. #Add point
   
5. geoshow(15, -100, size=14, color='r', marker='S')
   
6. #Add line
   
7. lat = [15, 0, -45, -25, nan, 15, -30, -60, -65]
   
8. lon = [-100, 0, 70, 110, nan, -100, -20, 100, 150]
   
9. geoshow(lat, lon, size=2, color='b')
   
10. #Add line and polygon
    
11. lat = array([30, 0, 18, 48, 30])
    
12. lon = array([60, 70, 130, 120, 60])
    
13. geoshow(lat, lon, color='r', size=2, linestyle=':')
    
14. lon = lon - 100
    
15. geoshow(lat, lon, displaytype='polygon', color=[150,230,230,230], edgecolor='b', size=2)
    
16. #Set extent
    
17. xlim(-180, 180)
    
18. ylim(-90, 90)
    
19. xticks(arange(-180, 181, 30))
    
20. yticks(arange(-90, 91, 30))
    
21. title('Add shapes')

axesm(tickfontsize=12)<br /> lworld = shaperead('D:/Temp/map/country1.shp')<br /> geoshow(lworld, edgecolor='k', facecolor='g')<br /> #Add point<br /> geoshow(15, -100, size=14, color='r', marker='S')<br /> #Add line<br /> lat = [15, 0, -45, -25, nan, 15, -30, -60, -65]<br /> lon = [-100, 0, 70, 110, nan, -100, -20, 100, 150]<br /> geoshow(lat, lon, size=2, color='b')<br /> #Add line and polygon<br /> lat = array([30, 0, 18, 48, 30])<br /> lon = array([60, 70, 130, 120, 60])<br /> geoshow(lat, lon, color='r', size=2, linestyle=':')<br /> lon = lon - 100<br /> geoshow(lat, lon, displaytype='polygon', color=[150,230,230,230], edgecolor='b', size=2)<br /> #Set extent<br /> xlim(-180, 180)<br /> ylim(-90, 90)<br /> xticks(arange(-180, 181, 30))<br /> yticks(arange(-90, 91, 30))<br /> title('Add shapes')

王老师这个怎么添加文本呢根据经纬度，不显示单个点，而是显示BEIJING。应该是text(142.5, 39, 'Fukushima', bold=True)
