Command Reference SynthWizard Step 2 Geographical extents of the scenery This step tells SynthWizard where will the scenery be located, and how large in geographical terms the scenery will be. You can enter geographical coordinates into the edit fields in both Decimal and DMS format:
TerraBuilder recognizes both formats, and the display mode is determined by DMS/Decimal switch at the TerraBuilder's bottom status bar. When the geographical coordinates are entered into edit fields, the opposing coordinate value (Maximum or Minimum) will be automatically calculated and updated, based on the resolution values given in the resolution edit fields, unless the resolution field is unlocked. See below for more information on this. Coordinate lock buttons These buttons determine from what location geographical extents calculation will automatically propagate when the resolution is not fixed (resolution buttons not locked). See below for more information. Resolution TerraBuilder's SynthWizard utilizes Combat Flight Simulator's synthetic textures in order to build the scenery terrain mesh. These textures are all 256 X 256 pixels in size. Since each texture represents an area of terrain, they have a certain size. This size has been selected to be 512 X 512 meters by default. This size also corresponds to exactly 2 meters per pixel in horizontal and vertical direction. This number is called resolution of the texture, and it has been arrived at simply by looking at the features in the bitmap and judging at their size in real life. Even though SynthWizard pre-sets this number at 2 meters/pixel in vertical and horizontal directions, you are free to un-lock these fields and change the values. If, however, you want to build a standardized SynthWizard scenery, it is recommended that the resolution be locked at the default setting of 2 meters/pixel Resolution lock buttons If you have the resolution buttons locked, the Latitude and Longitude values entered into the Max and Min fields will be automatically updated. For instance, if you have a horizontal resolution locked at 2m/pix, and enter a value for minimum Longitude, maximum longitude will be automatically updated based on the calculations involving minimum longitude and resolution. If, however, you have resolution buttons un-locked, you can:
The above applies equally to the minimum and maximum latitude values and vertical resolutions.
