Utah H3 Hexes Level 5

The H3 indexing system provides a standardized and high-performance grid for aggregating data at various levels. This layer contains the spatial representation of the IDs that cover the state of Utah. While it can be used for normal GIS point-in-polygon operations, you will get much better performance using the H3 API to assign a hex ID to your points, aggregating/analyzing your points based on ID, and then joining your aggregated data to this layer on the hex IDs. Our H3 blog post provides an overview of the system, an explanation of how we created these geometries, and an example analysis. Once the geometries were created in EPSG 4326 (WGS 84 lon/lat), they were projected to EPSG 26912 (UTM 12N) using the NAD_1983_To_WGS_1984_5 transformation.H3索引系统（H3 indexing system）提供了一套标准化且高性能的网格体系，可支持不同层级的数据聚合操作。本图层包含覆盖犹他州全境的所有H3索引ID的空间表征。尽管该图层可用于常规地理信息系统（GIS）的点在多边形内运算，但通过H3 API为你的点位分配六边形网格ID、基于该ID对点位进行聚合与分析，再将聚合后的数据通过六边形网格ID与本图层进行关联，可获得显著更优的运算性能。我们的H3官方博客文章对该系统进行了概述，讲解了此类空间几何数据的生成方式，并附带了一则分析示例。此类空间几何数据首先以EPSG 4326（WGS 84经纬度坐标系）格式生成，随后通过NAD_1983_To_WGS_1984_5坐标转换，投影至EPSG 26912（UTM 12N）坐标系。
