Class for doing transforms between two map coordinate systems.
The feature class encapsulates a single feature including its unique ID, geometry and a list of field...
Definition: qgsfeature.h:56
Stores coordinates of a tile in a tile matrix set.
Definition: qgstiles.h:38
This class is responsible for decoding raw tile data written with Mapbox Vector Tiles encoding.
Encapsulates properties of a vector tile matrix set, including tile origins and scaling information.
QMap< QString, QVector< QgsFeature > > QgsVectorTileFeatures
Features of a vector tile, grouped by sub-layer names (key of the map)
