Vector Tile FAQ

About the data coordinate system:

Q:	Just started the Generate Vector Tile, but prompted that the build failed.
Answer:	Check the map data to see if the coordinate system of the data cannot be converted to the map Display Coordinates system or if the coordinate system of the data is a Planar Coordinate System. If it exists, the coordinate system of the data is processed first, so that it can be correctly converted to the map Display Coordinates system.

About Vector Tile missing layers:

Q:	Unique values Map is used in the map, and Offset Settings is used to simulate the three-dimensional shadow of the building, which is missing in the Vector Tile, as shown in Figure 1 above.
Answer:	Currently, MapBox does not support Offset Settings for Unique-values maps.
Q:	Individual layers in the map are not displayed in the cut Vector Tile.
Answer:	This is mostly because the Vector Tile is displayed based on the MapBox style, which is not supported by some of SuperMap's symbol or Layer Settings MapBox styles. Therefore, please check whether the map data uses some unsupported styles and other settings, such as whether there is an unsupported thematic map, whether the missing layer is a CAD layer (Vector Tile does not support CAD layers), etc.

About Vector Tile deformation problem:

The cut-out Vector Tile? Element is distorted, generally appearing in administrative boundaries and river elements.

Answer:

The main reason for feature deformation is the result of thinning node-dense objects by Vector Tile during Generate Vector Tile. It is recommended that maps use objects of appropriate complexity at small scales. For example, this situation is listed in "Reducing Data Complexity" in Cartographic Best Practices. There is another situation. If this situation occurs after the Vector Tile is zoomed in, it means that the scale level of your cut map is not enough. You only need to increase the scale level of the cut map, as shown in the following figure.
