Question

在超图移动端调用，wmts100与wmts-china.

两种的区别是什么。将这两种服务为什么不能与天地图wmts服务一起用？

    private boolean openMap(){

        m_workspace = new Workspace();
        m_mapView = (MapView)findViewById(R.id.Map_view);
        m_mapControl = m_mapView.getMapControl();
        m_mapControl.getMap().setWorkspace(m_workspace);

您好，图层能否叠加使用需要看数据的坐标系是否一致，您的这两个服务的坐标系是什么呢？
