Patent, Dynamic Vector Map Tiles US 62044949

本公开涉及用于提供用于在制图应用程序中生成地图视图的矢量地图数据的系统和过程. 在一个示例流程中，对矢量地图子图的请求可以由地图服务器接收. 地图服务器可以识别与请求的矢量地图子图对应的预生成的矢量地图图块. 它可以通过将矢量地图块划分为两个或多个矢量地图子块，从已识别的矢量地图块生成所请求的矢量地图子块. In some examples, 将矢量地图瓦片划分为多个矢量地图子瓦片可以包括识别应包含在请求的矢量地图子瓦片中的矢量地图瓦片的特征和属性，并生成请求的矢量地图子瓦片以包含这些特征和属性. 地图服务器可以将所请求的矢量地图子图传送到所请求的电子设备.
