百度和谷歌地圖顯示區(qū)域輪廓示例
作者：劉明
最近項(xiàng)目中需要實(shí)現(xiàn)用地圖顯示各省份區(qū)域銷售業(yè)績(jī)的統(tǒng)計(jì)功能，即省份用不同顏色標(biāo)示出來?；〞r(shí)間研究了下，其實(shí)Google Map 和 Baidu Map 都有相關(guān)實(shí)現(xiàn)方法。即 獲取區(qū)域輪廓坐標(biāo)系，然后繪制自定義圖層。
最近項(xiàng)目中需要實(shí)現(xiàn)用地圖顯示各省份區(qū)域銷售業(yè)績(jī)的統(tǒng)計(jì)功能，即省份用不同顏色標(biāo)示出來。
花時(shí)間研究了下，其實(shí)Google Map 和 Baidu Map 都有相關(guān)實(shí)現(xiàn)方法。即 獲取區(qū)域輪廓坐標(biāo)系，然后繪制自定義圖層。
