arcgis api for javascipt 加載天地圖、百度地圖

標籤 arcgis api javascipt 加載 地圖 百度 欄目 Java 简体版
原文   原文鏈接

寫在前面的話：javascript

1.百度地圖是本身定義的座標系統，wkid=102100.百度地圖數據是加密的產物。下文將附上百度座標與WGS84，谷歌等座標系統轉換方法（地理-地理），此方法並未親測，聽說準css

2.百度地圖能夠直接加載經緯度座標html

3.百度地圖若是加載的arcgis api中會出現座標偏移，1.中已經解決了地理座標轉換，那麼找到百度投影-地理座標的轉換方式，則arcgis就能夠直接無偏加載了，網上不少方法，可是親測不行。java

4.天地圖不是涉密數據，根據本文提供的類庫,arcgis api for js能夠直接加載。可是數據有略微的偏移jquery

 

 

天地圖的切片地圖能夠經過esri.layers.TiledMapServiceLayer來加載，在此將之進行了必定的封裝，以下：api

一、切片線劃圖——TDTLayer.jsdom

封裝好以後就能夠在頁面調用了，調用的時候須要導入這些自定義的圖層，導入方式爲：ide
