我在發現ArcGIS的Drawing tool。小部件的代碼如下所示:使用ArcGIS的繪圖工具

我對ArcGIS非常陌生,因此我的問題可能很簡單。我想知道是否有可能用其他圖像代替背景地圖,例如,代表建築物內某層的圖層?我有這個圖像可用JPEG格式,它有全局座標分配給它。那麼,我該如何用這張圖片替換地圖呢?我應該更新這些代碼行嗎?
map = new Map("map", {
basemap: "streets",
center: [-15.469, 36.428],
zoom: 3
});
將來自Esri的預先製作的底圖替換爲不同的圖像(例如建築物的地板)將需要發佈平鋪的圖像服務。 – Erica
不要一字不差......試着理解這個問題。不過,我也知道發佈/更新底圖/平鋪服務的過程。在投票之前,我想你只需要閱讀我在答案中添加的註釋。你真的認爲這個人在問我如何使用新的圖像數據發佈一個新的底圖。只有客觀的提到在這個問題上,我該如何改變背景。這就是爲什麼我明確提到,我要求你嘗試現有的弧形底圖..(Y):) –
順便說一句,謝謝你指出我也添加這個答案... –
