vectortiles:Mapbox矢量图块的本机Haskell编解码器-源码
VectorTiles什么是VectorTiles?由发明,是有限大小的图块和矢量几何形状的组合。
Mapbox维护VectorTile编解码器的官方实现规范。
VectorTiles优于栅格图块,因为:它们通常较小以存储它们可以实时轻松地进行转换(旋转等)它们允许在“SlippyMaps”中连续(而不是逐步)缩放。
原始VectorTile数据以protobuf格式存储。
任何实施编解码器都必须根据对数据进行解码和编码。
这是什么图书馆?vectortiles是VectorTile规范2.1版的最小可行实现。
它旨在为实现其他编解码器提供坚实的参考。
vectortiles公开了原始protobuf数据与更高级的VectorTile类型之间的转换函数的小型API,VectorTile类型更有助于进一步处理。
vectortiles还公开了典型的GISGeometry类型的相当简单(但很明智)的实现:点LineString多边形为了便于编码和解码,每个Geometry类型及其对应的Multi(即Multipoint)都被视为同一事物,即那 本软件ID:14993176
