| Description |
|
API Support for searches such as "which points have the most other points within a certain radius." This ability would in turn open up the door for variations such as which points have the least, which points are furthest away from all other points, which points are more densely surrounded by other points, etc. Currently the only way to do this is to build a quad tree using our indexes and points application side. Would be nice to have a way to do this natively to geo indexes. |

Think this belongs more in the aggregation/query/M-R framework than geo features specifically - density analysis is useful for lots of things, not just geospatial data. That being said, "unwinding" and "grouping" shapes into raster grids and performing analysis on the aggregate properties is something we've discussed - we're still trying to consolidate the above frameworks to make it easier to add these new features. Changed the title to avoid confusion with our current $geoNear searches. |
