我们使用python的pyshp库将文本文件转化为shape file
import shapefile
w = shapefile.Writer(shapeType=shapefile.POINT)
w.field("name1", "C")
w.field("name2", "C")
w.field("name3", "C")
w.field("name4", "N")
with open("test.txt") as f:
for line in f:
lng = **
lat = **
name1 = **
name2 = **
name3 = **
name4 = **
w.record(name1, name2, name3, name4)
w.point(lng, lat)
w.save('test')
leaflet() %>%
addTiles(

options=tileOptions(tileSize=256, minZoom=9, maxZoom=20, subdomains="1234"),

addWMSTiles(

) %>%
addLayersControl(
overlayGroups = c("地图", "GeoServer"),
options = layersControlOptions(collapsed = FALSE)
) %>%
setView(116.489528,40.004535, zoom = 16)
EPSG:4326的访问链接格式如下,可以获得一个bbox内的所有属性,返回JSON格式:
http://example.com/geoserver/xxx/wfs?
service=wfs&
version=2.0.0&
request=GetFeature&
typeNames=namespace:featuretype&
count=50&
outputFormat=json&
bbox=lat1,lng1,lat2,lng2
