Qt/Qml:如何包含地图瓦片以供离线使用? [英] Qt/Qml: how to include map tiles for offline usage?

问题描述

我需要在一个主要在 Android 和 iOS 上运行的 Qt/Qml 移动应用程序中包含离线图块(滑动地图).

I need to include offline tiles (slippy map) into a Qt/Qml mobile application that mainly runs on Android and iOS.

我找到的唯一一个有据可查且有效的解决方案是用于 Qt 的商业 Esri Arcgis Runtime.但是，创建切片包需要使用 Arcgis 堆栈，无论是桌面还是服务器(如果我弄错了，请纠正我).

The only well-documented and working solution I found is the commercial Esri Arcgis Runtime for Qt. However, creating tile packages requires using the Arcgis stack, either desktop or server (please correct me if I am mistaken).

我正在寻找一种开源且易于使用的替代方案.

I am looking for an open source and easy to use alternative.

QtLocation 刚刚在 Qt 5.5 中得到了改进，但那里似乎没有针对离线 tile 包的开箱即用解决方案:

QtLocation has just been improved in Qt 5.5, but there seems to be no out of the box solution for offline tile packages there:

推荐答案

现在可以通过 ArcGIS Runtime 库使用离线地图，从版本 10.2.6 开始:

Using offline maptiles is now possible through the ArcGIS Runtime library, starting from version 10.2.6:
