Text overlay (waypoint or route map label, e.g.) Set of points describing a filled shape or line (map drawing, etc) List of points lat/lon/ele/timestamp point Maximum scale at which the parent object is displayed on a map. "24000" for a 1:24000 scale USGS topo, e.g. Text overlay (waypoint or route map label, e.g.) User-specified lat/lon position for the text label. User-specified x/y offset for the text label. Rotation of text label. Clockwise from 0 (default English text direction to the right) Spacing from edge of parent object (waypoint symbol, track line) to label origin. Explicit 0 centers label origin. Sign of x,y margin implies horizontal and vertical alignment of text. The text string to display Specifies that the text string in the overlay was derived from a GPX field or a calculated attribute of the parent. "desc" means the text string came from the parent's desc field. "area" signifies the text string is the calculated area of the parent. Type (classification) of the text overlay. Maximum scale at which the parent object is displayed on a map. "24000" for a 1:24000 scale USGS topo, e.g. Text styling hints for the text overlay styling hints for bounding box of the the text overlay styling hints for the background of the bounding box of the text overlay You can add extend GPX by adding your own elements from another schema here. polyline represents an ordered list of points describing a closed or open shape. Description of polyline. Type (classification) of polyline. Maximum scale at which the parent object is displayed on a map. "24000" for a 1:24000 scale USGS topo, e.g. Map label for polyline polyline line style polyline fill style You can add extend GPX by adding your own elements from another schema here. A segment of connected pt elements. Analogous to trkseg. A geographic point with optional elevation and time. Available for use by other schemas. The elevation (in meters) of the point. The time that the point was recorded. The latitude of the point. Decimal degrees, WGS84 datum. The latitude of the point. Decimal degrees, WGS84 datum. An ordered sequence of points. Ordered list of geographic points. Offset in x,y dimensions (screen or printed page). Units in millimeters. Horizontal offset. Vertical offset. The latitude of the point. Decimal degrees, WGS84 datum. The longitude of the point. Decimal degrees, WGS84 datum. Used for bearing, heading, course. Units are decimal degrees, true (not magnetic).
