NAME

Limit - Limits the number of waypoints in a set

DESCRIPTION

START HELP

This module limits the number of waypoints in a set to a certain number (starting at an optional certain point in the list of waypoints).

IE, it starts at the offsetth waypoint in the set being modified, and limits the total number to number, stripping off all of the waypoints before the offset first and then everything from offset+number next.

If just number is specified (the common case) the firest number waypoints are kept.

If there are 250 caches in the set:

number = 100, offset = 0

Will get the first 100 caches

number = 100, offset = 100

Will get the next 100.

number = 100, offset = 200

Will get the last 50.

This module is very useful when combined with the distance and sortby modify pluigns to get the top 10 caches (for example) near something:

   geoqo -s 'set:import:mypocketquery' -m distance:from=GCABCD+sortby:+limit:10
