绘制中国地图进阶
在上一篇文章《ggplot2 + sf + 高德地图数据绘制中国地图》,笔者介绍了如何利用 ggplot2 + sf + 高德地图数据绘制中国地图。本文继续讨论绘制中国地图问题,重点解决以下两个问题:其一,数据来源由第三方地图服务切换为权威官方网站,以确保数据的规范性和权威性;其二,坐标系采用 2000 国家大地坐标系(CGCS2000),投影方式选用 Albers 等面积圆锥投影(基准面:CGCS2000),其中中央经线设定为 105°E,标准纬线分别取 25°N 和 47°N,从而更好地满足专业学术论文投稿要求和正式场合展示。
数据来源
如果只是一般的学习交流使用,我建议你使用高德地图平台的数据,地图数据完整且包含各省区行政中心和质心经纬度坐标,非常容易获取,如果是学术论文投稿和正式场合,那必须从权威官方网站获取。以下两个网站是目前最权威的数据来源,推荐使用。
