地理标记语言gml的问题
求大神帮忙,如何用gml表达如下两个事物(coordinate system: EPSG=4326),要求用FeatureCollection作为root element, 并且要用到featureMember:
1 road
Name: E22
Type: Motorway
Geometry: Line (choose your own coordinate values)
1 local municipality
Name: Lund
Inhabitants: 100 000
Geometry: Polygon (choose your own coordinate values).
我自己尝试写了下,可以肯定的是我肯定犯错了:
55,13 57,16
Road
E22
Motoway
55.7,13.2 56.0,14.2
Municipality
Lund
100000
55.7,13.2
