武汉市二手小区房价可视化
1.数据收集及预处理
从武汉市公共服务平台收集了武汉市二手房数据共54000条,对数据进行查重、地址标准处理、去空值后得到2960条小区数据。但是缺少经纬度信息无法进行可视化,因此借助百度API进行地理编码。

2.调用百度API进行地理编码
申请了百度API的AK后,调用其地理编码功能,根据小区地址获得其经纬度,最终整理为武汉二手房小区房价的shp数据。

3.使用QGIS进行坐标纠偏
直接使用得到的坐标,与发现与现有的实际poi位置不符,发现百度地图使用的坐标系还要进行二次转换,遂决定用QGIS Geohey插件进行处理。参考QGIS转坐标

4.核密度分析
Arcgis 核密度分析功能得到最终的图层,发现果然h是江岸、江汉、武昌区房子比较贵哈。
