What is striking at first glance is the redundancy of p[i] and p[j]: do cache those vectors inside some vars. Worst case, you can make the envelope very small, and use a point-in-poly algorithm to confirm that the center point is within the geometry (count the number of times a line extended from the point to a point past the eastern [or western] edge of the shape envelope crosses the segments [treating the second point as if it isn't part of the line. Prior to SQL Server 2008, geography locations such as bank branches, restaurant locations and household locations, are usually stored as latitude and longitude coordinates in two separate columns. [23] discussed the architectural comparison of two spatial big data systems SpatialHadoop [8] and GeoSpark [19], where they show that GeoSpark is faster in processing spatial data. The first step is to compute an H3 index for each feature (points, polygons, …) defined as UDF geoToH3(…).
