[英]cannot get the google satelite image with a bounding box
I want to extract google satellite images in r. 我想在r中提取谷歌卫星图像。
I actually manage to get my image using the coordinates but not with the bounding bx 我实际上设法使用坐标获取我的图像,但不使用边界bx
first you need to get a google api key and register it then 首先,你需要获得一个谷歌API密钥并注册它
GE <- get_map(location = c(long =36.8595894, lat=-0.7688972) ,
maptype = "satellite", zoom=18)
ggmap(GE)
This works 这有效
then i want to make a bounding box 然后我想做一个边界框
box<-make_bbox(c(36.8594652,36.8597136),c(-0.7691144,-0.7686799 ) )
GE <- get_map(box ,
maptype = "satellite", source="google",
zoom=18)
This however does not return a satellite image, why? 然而,这不会返回卫星图像,为什么?
it seems to return a ggmap but not from google and it is not viewable with ggmap(GE) 它似乎返回一个ggmap但不是谷歌,它不能用ggmap(GE)查看
Ok, Camille is right, it is just not an option ind get_googlemap, this is however not straight forward when just looking at vignette of the wrapper function get_map. 好的,Camille是对的,它不是get_googlemap的选项,但是当看到包装函数get_map的插图时,这不是直截了当的。
I found this post ggmap extended zoom or boundaries that shows how to handle the boundaries and zoom with google image. 我发现这个帖子ggmap扩展缩放或边界 ,显示如何处理边界和使用谷歌图像缩放。
