Coordinate maps display geographic areas overlaid with circles keyed to the data determined by the buckets you specify. To use coordinate maps, you plot latitude and longitude coordinates.
When you deselect *Change precision on map zoom*, the *Precision* slider appears. The *Precision* slider determines the granularity of the results displayed on the map. For details on the area specified by each precision level, refer to {ref}/search-aggregations-bucket-geohashgrid-aggregation.html#_cell_dimensions_at_the_equator[geohash grid].
NOTE: Higher precisions increase memory usage for the browser that displays {kib} and the underlying
{es} cluster.
When you select *Place markers off grid (use {ref}/search-aggregations-metrics-geocentroid-aggregation.html[geocentroid])*, the markers are
placed in the center of all documents in the bucket, and a more accurate visualization is created.
NOTE: When you have multiple values in the geo_point, the coordinate map is unable to accurately calculate the geo_centroid.
