I’ve got a basic SQL query that looks like: SELECT TOP 1 [geom].STBuffer(500) FROM [db].[dbo].[boundaries]
I am trying to work out the most efficient query to get points within a radius of a given point. The results do not have to be very accurate so I would favor speed over accuracy.
I have +10k points (latitude, longitude) and I\'m building an app that shows you the k nearest points to a user\'s location.
I am looking to refactor this method (from Massive.cs by Rob Conery): public static void AddParam(this DbCommand cmd, object item) {
I have a set P of 2D points that I could like to cluster in a 2D uniformly spaced grid, where each cell is length X.
I am working on Grails 1.3.2 with MySql. I need to store the latitude and longitude of certain locations in the database and then on the basis of the user\'s current location, I need to return the ite
I\'m trying to store a database of GPS locations and run queries which find the points within a given radius and also the closest points.I\'m using mysql and have been looking at the spatial extension
I have geographic data that was loaded into the geography datatype. For very specific purposes, I now need to have store this as a geometry. However, I need to perform a query like this.开发者_StackOv
I need a data structure for doing 2d range counting queries (i.e. how many points are in a given rectangle).
I\'m using this plugin to allow spatial queries in Solr. I have followed the steps included in the documentation and I\'ve got the spatial queries working fine.
