2D Map

The 2D map Viewpoint type allows users to configure an output window displaying the desired objects on an equidistant-cylindrical map of the desired celestial body. A Map command can be used to create a 2D map view, or a ViewWindow object with a 2D map Viewpoint can be used. The following is a list of the configurable options for a 2D map Viewpoint.

•Reference Frame

•Mapped Body

•Map width and height

•Map center point - either latitude/longitude coordinates, or the subsatellite point of a specified Spacecraft object

•Display settings for the latitude/longitude grid

The script example below shows how to create a custom 2D Map Viewpoint centered on 70 degrees West, 35 degrees North on the Earth's surface, and add it to a ViewWindow. We are also showing how to turn on latitude and longitude grid lines, set the label locations, and adjust the label font.

// Create Map Viewpoint

Viewpoint MapViewpoint;

MapViewpoint.ViewpointType = "map";

MapViewpoint.ViewpointName = "Map View";

MapViewpoint.MapView.ReferenceFrame = "body fixed";

MapViewpoint.MapView.Body = Moon.ObjectId;

MapViewpoint.MapView.CenterLongitude = 230;

MapViewpoint.MapView.CenterLatitude = 5;

MapViewpoint.MapView.Width = 300;

MapViewpoint.MapView.Height = 90;

MapViewpoint.MapView.ShowLatitudeLongitudeGrid = 1; // Turns Lat/Long grid on

MapViewpoint.MapView.LatitudeGridLabelLocation = 2; // Sets Latitude grid on right

MapViewpoint.MapView.LongitudeGridLabelLocation = 3; // Sets Longitude grid on bottom and top

MapViewpoint.MapView.LatitudeGridLabelFont.Bold = 1; // Configure Latitude grid font

MapViewpoint.MapView.LongitudeGridLabelFont.Bold = 1; // Configure Longitude grid font

// Add Viewpoint to a ViewWindow and activate it

ViewWindow ViewWindow1({Spacecraft1});

ViewWindow1.AddViewpoint(MapViewpoint);

ViewWindow1.ActivateViewpoint(MapViewpoint.ViewpointName);

Update ViewWindow1;
