I'm running v100.1 and I'm trying to get the spatial reference for a base map from a tile package I've loaded. This worked in 10.2.6 where I loaded this same tile package in QML and could print out latestWkid (3857) and wkid (102100). Now I am reading the same tile package in my v100.1-based C++/Qt Quick application and always get -1 as wkid. So I went to the basic MyFirstMap - you know the starter code from the wizard - and tried to get wkid from it. I added the last four lines of code in the snippet below. I'm getting -1 for both m_map's and m_mapView's spatial reference. Shouldn't I be getting something valid? There must be something fundamental that I'm missing.
Thanks!
void MyFirstMapV100::componentComplete()
{ QQuickItem::componentComplete();
// find QML MapView component
m_mapView = findChild<MapQuickView*>("mapView"); m_mapView->setWrapAroundMode(WrapAroundMode::Disabled);
// Create a map using the imageryWithLabels BaseMap
m_map = new Map(Basemap::imageryWithLabels(this), this);
// Set map to map view
m_mapView->setMap(m_map);
SpatialReference sr = m_map->spatialReference();
qDebug() << sr.wkid(); // returns -1
sr = m_mapView->spatialReference();
qDebug() << sr.wkid(); // returns -1
}
Also, here's an excerpt showing how I'm loading my tile package base map from my application. Again, I'm getting -1 for the spatial references.
TileCache* tileCache = new TileCache(m_dataPath + "xyz.tpk");
ArcGISTiledLayer* tiledLayer = new ArcGISTiledLayer(tileCache, this);
// What is the spatial reference?
SpatialReference sr = tiledLayer->spatialReference();
qDebug() << sr.wkid(); // returns -1
Basemap* basemap = new Basemap(tiledLayer, this);
m_map = new Map(basemap, this);
// What is the spatial reference?
sr = m_map->spatialReference();
qDebug() << sr.wkid(); // returns -1
