plot-map 0.1.6

A tool to add basemap in matplotlib

plot_map

plot_map是一个基于matplotlib的工具，在用geopandas或者pyplot绘制地理图形的时候，你可以用plot_map来添加地图底图
When you want to plot geo object using python geopandas or matplotlib.pyplot, you can use this module to generate map backgroud.

安装

pip install plot-map

示例

地图底图加载

只需要用以下代码：
Just use the following code:

import plot_map
#设定显示范围
bounds = [lon1,lat1,lon2,lat2]  
plot_map.plot_map(plt,bounds,zoom = 12,style = 4)  

你可以通过改变参数"style"和"styleid"来改变底图的风格样式
You can change your map style by changing the "style" and "styleid" in the function plot_map

bounds -- Set your plotting boundary [lon1,lat1,lon2,lat2] (wgs1984) 底图的绘图边界，[lon1,lat1,lon2,lat2] (WGS84坐标系) 其中，lon1,lat1是左下角坐标，lon2,lat2是右上角坐标
zoom -- The zoom level of the map  底图的放大等级，越大越精细，加载的时间也就越久，一般单个城市大小的范围，这个参数选取12到16之间
style -- From 1 to 7 represent different map styles,1-6 is from openstreetmap and 7 is the mapbox    地图底图的样式，可选1-7
styleid -- if style is set as 7(from mapbox), you can change the styleid here, "dark" or "light" or your own style  
imgsavepath -- Path to save the tile map so that you don't have to download again瓦片地图储存路径，设置路径后，会把地图下载到本地的文件夹下，使用时也会优先搜索是否有已经下载的瓦片，默认的存放路径是C:\\
printlog -- Show the log

绘制指北针和比例尺的功能plotscale

plot_map.plotscale(ax,bounds = bounds,textsize = 10,compasssize = 1,accuracy = 2000,rect = [0.06,0.03])
