Description
Use the MapProjection command to set the graphical display of the central body in the 2D Graphics window.
If you don't specify the optional <WinNumber>, the first map window is used. If you specify a window number that doesn't exist, Connect returns a NACK.
Valid values for {ProjectionType} are outlined in the following Table.
| {ProjectionType} | {ProjectionOption} & <Parameters> |
|---|---|
| EquiCylindrical | Center <LonCenter> |
| Mercator | |
| Miller | |
| Mollweide | |
| Sinusoidal | |
| HammerAitoff | |
| AzimuthEqui | Center <LatCenter> <LonCenter> |
| Stereographic | |
| Orthographic | {ProjectionOption} <Parameters>, as defined in the Table below. |
| Perspective |
All <LatCenter> and <LonCenter> values are entered in degrees.
Options for the Orthographic projection are:
| {ProjectionOption} | <Parameters> |
|---|---|
| Center | <LatCenter> <LonCenter> |
| Format | {CoordFrame} <Value> [<SecondaryBody>]
where {CoordFrame} can be ECF, ECI, or BBR. If {CoordFrame} is BBR, specify the <SecondaryBody> to be used as the reference frame. <Value> is a display height entered in Connect distance units, greater or equal to 1.0. |
| Grid | {On | Off} [<NumXLines> <NumYLines> <Color>]
where <NumXLines> and <NumYLines> are between 0 and 100. |
Options for the Perspective projection are:
| {ProjectionOption} | <Parameters> |
|---|---|
| Center | <LatCenter> <LonCenter> <Altitude> |
| Format | {CoordFrame} <Value> [<SecondaryBody>]
where {CoordFrame} can be ECF, ECI, or BBR. If {CoordFrame} is BBR, specify the <SecondaryBody> to be used as the reference frame. <Value> is a field of view in degrees, between 1.0 and 180.0. |
Examples
To use a perspective map projection with an ECF reference frame and a field of view of 90.0 degrees:
To use an Orthographic map projection with a grid:
To set the map projection to EquiCylindrical with the longitude center at 90.0 degrees:
To set the map projection to HammerAitoff for map window 2:
