我想从维基共享资源中检索图像以在地图上显示。这意味着给定一对(纬度,经度)我想在这一点找到图片。 经过一天的搜索和尝试,我仍然不知道这是否可能。我特别推荐MediaWiki API Main page,API reference和some examples。
所以我的问题是:是否可以检索具有一对地理坐标的图片?如果是,怎么样?
答案 0 :(得分:12)
action=query&list=geosearch&gscoord=lat|lon&gsradius=meters&gsnamespace=6&gsprimary=all
摘自API文档
gscoord - Coordinate around which to search: two floating-point values separated by pipe (|)
gspage - Title of page around which to search
gsradius - Search radius in meters
This parameter is required
The value must be between 10 and 10000
gsmaxdim - Restrict search to objects no larger than this, in meters
gslimit - Maximum number of pages to return
No more than 500 (5000 for bots) allowed
Default: 10
gsnamespace - Namespace(s) to search
Values (separate with '|'): 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 100, 101, 102, 103, 104, 105, 106, 107, 460,
461, 490, 491, 1198, 1199, 828, 829
Maximum number of values 50 (500 for bots)
Default: 0
gsprop - What additional coordinate properties to return
Values (separate with '|'): type, name, dim, country, region, globe
Default: globe
默认情况下,MediaWiki中的文件命名空间为NS 6。
结果:
{
"query": {
"geosearch": [
{
"pageid": 28971703,
"ns": 6,
"title": "File:RiveuferHerbst.JPG",
"lat": 51.501042,
"lon": 11.948794,
"dist": 142.8
},
{
"pageid": 32760810,
"ns": 6,
"title": "File:Pei\u00dfnitznordspitze4.JPG",
"lat": 51.499675,
"lon": 11.947992,
"dist": 143.6
}
]
}
}
如果您还希望使用API请求获取缩略图网址,请使用list=geosearch
作为生成器:
结果:
