  • performing, by a first device;

    receiving a message sent by a second device, wherein the message relates to joining a group;

    based on receipt of the message sent by the second device, sending first location information to a first server and receiving second location information from the first server, the first location information comprising a location of the first device, the second location information comprising one or more locations of one or more respective second devices included in the group;

    sending, from the first device to a second server, a request for georeferenced map data;

    receiving, from the second server, the georeferenced map data;

    presenting, via an interactive display of the first device, a georeferenced map and one or more user-selectable symbols corresponding to one or more of the second devices, wherein the symbols are positioned on the georeferenced map at respective positions corresponding to the locations of the second devices represented by the symbols, and wherein the georeferenced map data relate positions on the georeferenced map to spatial coordinates; and

    identifying user interaction with the interactive display selecting a particular user-selectable symbol corresponding to a particular second device and user interaction with the display specifying an action and, based thereon, using an Internet Protocol to send data to the particular second device,wherein identifying the user interaction selecting the particular user-selectable symbol comprises;

    detecting user selection of a portion of the interactive display corresponding to a position on the georeferenced map, andidentifying the particular user-selectable symbol based, at least in part, on coordinates of the selected position, comprising;

    searching a set of symbols for a symbol located nearest to the coordinates of the selected position, wherein the set of symbols includes the user-selectable symbols corresponding to the second devices in the group, and wherein data associated with the set of symbols include coordinates of portions of the display corresponding to the symbols in the set, andbased on a result of searching the set of symbols, identifying the particular user-selectable symbol as the symbol located nearest to the coordinates of the selected position, wherein the particular user-selectable symbol corresponds to the particular second device.
