Properties for the 2D Graphics Window

2D Graphics Details

The 2D Graphics Details page enables you to:

Typically, you do not use map detail items when you choose a background image. STK is shipped with the Relational World Data Bank II (RWDBII) maps. RWDBII maps, originally used by the CIA, are now publicly available and are known for their accuracy.

Map Details

Select the map detail items (binary, ASCII, or shapefiles) that you want to display in the 2D Graphics window from the Map Details list. The list includes map details that reside in the following directories:

  • <STK install folder>\STKData\CentralBodies\<central body name>\maps\binary\lendian
  • <STK install folder>\STKData\CentralBodies\<central body name>\maps\ascii
  • <STK install folder>\STKData\CentralBodies\<central body name>\maps
  • <STK user area>\CentralBodies\<central body name>\maps\binary\lendian
  • <STK user area>\CentralBodies\<central body name>\maps\ascii
  • <STK user area>\CentralBodies\<central body name>\maps
  • <STK all users area>\CentralBodies\<central body name>\maps\binary\lendian
  • <STK all users area>\CentralBodies\<central body name>\maps\ascii
  • <STK all users area>\CentralBodies\<central body name>\maps
  • <STK scenario folder>\CentralBodies\<central body name>\maps\ascii
  • <STK scenario folder>\CentralBodies\<central body name>\maps
  • <STK install folder>\AGI\Earth\HiResMaps\binary\lendian

The name of each item in the list is derived from the name of the string contained in a file called name.

To add a shapefile to the Items list, create a subdirectory in one of the directories listed above and then place the shapefile along with the name file into the newly-created subdirectory. Esri shapefiles must have a projection file (.prj) that matches the central body definition.

If you want to assign a unique color to more than one shapefile, place each shapefile in its own folder.

Advanced button. Click the Advanced Map Details button to select more specific map details and set the color for all map details. The Advanced Map Details page displays.

Lat/Lon Lines

To display latitude and longitude lines in the 2D Graphics window, enable Show and set the following display options.

Lat Spacing. Defines the distance between latitude lines.

Lon Spacing. By default, spacing between longitude lines is the same as the spacing between latitude lines. To define the distance between longitude lines, enable Lon Spacing and enter a new value.

Color. The color of the latitude and longitude lines.

Line Style. The style of the latitude and longitude lines in the 2D Graphics and 3D Graphics windows.

If you set very small latitude/longitude line spacing, performance may decrease unless only a small portion of the central body is visible in the 2D Graphics window.

Clouds

Cloud File. If enabled, images of clouds are overlaid in the 2D Graphics window. Use the button to locate and select the cloud index file of choice. Cloud files must end in a .cld or .pgm extension.

You can also associate a .pos file (position file) with a cloud file, giving you the ability to create a cloud file for a specific latitude and longitude region. To associate a .pos file with a cloud file, place the .pos file in the same directory as the cloud file.

Terrain Regions Display

Show Extents. If enabled, an outline displays around imported terrain regions on the map.
