Use this pull-down menu to select the maximum number of locations to allow at any given time. If there are too many locations to map at once, a subset are displayed based on the current map view and your selected criteria: maximum number allowable, selection method, date range, and time range.
warning: The more points you allow, the longer the map takes to render all of the necessary markers. As you exceed a few hundred markers, your browser may show noticeable delay or grow unresponsive.
