Geolocation plugin displays node location on Google map, depending on SNMP OID system.SysLocation and system setting Prepend location. When plugin is installed, new tab Geo mapping is being added next to configuration backup tab. When data is obtained from Google Maps API, tab will contain map with actual node location, node model and IP-address. Plugin's documentation is available here.

STP mapping plugin displays spanning tree, related to the particular node. STP data can be collected from nodes within scheduled task stp. The task itself is built-in and doesn't depend on plugin. The plugin is responsible only for displaying STP tree, not for collecting data from nodes. Thus task stp will remain in the system even if you uninstall the plugin, ensure to handle it in a proper way, removing from schedule if it's unnecessary. Plugin's documentation is available here.
