地理空间几种数据格式

一、wkt

点
point(0 0)
线：
linestring(0 0,1 1,2 2)
面
polygon((0 0, 30 0, 30 30,0 30, 0 0))
polygon((10.02 20.01, 11.92 35.64, 25.02 34.15, 19.15 33.94, 10.02 20.01))
multipolygon (((10.02 20.01, 11.92 35.64, 25.02 34.15, 19.15 33.94, 10.02 20.01), (51.71 21.73,73.36 27.04,71.52 32.87, 52.43 31.90, 51.71 21.73)))
POLYGON ((11.234395393474088 30, 11.92 35.64, 25.02 34.15, 19.15 33.94, 16.567645369705673 30, 11.234395393474088 30))
polygon ((40 120, 90 120, 90 150, 40 150, 40 120),(50 130, 60 130, 60 140, 50 140, 50 130), 
(70 130, 80 130, 80 140, 70 140, 70 130))
GEOMETRYCOLLECTION (POLYGON ((0 0, 0 1, 1 1, 1 0, 0 0)), POLYGON ((3 3, 3 5, 7 9, 12 11, 11 2, 3 3)))
MULTIPOLYGON (((11.92 35.64, 11.234395393474088 30, 16.56764536970567 30, 10.02 20.01, 11.92 35.64)), ((19.15 33.94, 16.567645369705673 30, 16.56764536970567 30, 19.15 33.94)))

{"type":"MultiPolygon","coordinates":[[[0,0],[0,20],[20,20],[20,0],[0,0]],[[0,0],[0,10],[10,10],[10,0],[0,0]]]}
{"type":"Polygon",
"coordinates":[[[0.0,-10],[-3.0902,-9.5106],[-5.8779,-8.0902],[-8.0902,-5.8779],[-9.5106,-3.0902],

[9.0902,-5.8779],[6.8779,-8.0902],[4.0902,-9.5106],[1,-10],[0.0,-10]]]}
{"type":"MultiPolygon","coordinates":[[[40,120], [90, 120], [90, 150], [40, 150], [40 ,120]],[[50, 130], [60, 130], [60, 140], [50, 140], [50, 130]], 
[[70, 130], [80, 130], [80, 140], [70, 140], [70, 130]]]}
{"type":"GeometryCollection","geometries":[{"type":"Polygon","coordinates":[[[0.0,0.0],[0.0,1],[1,1],[1,0.0],[0.0,0.0]]]},{"type":"Polygon","coordinates":[[[3,3],[3,5],[7,9],[12,11],[11,2],[3,3]]]}]}
