Results

Note: The correlation between the resolution and the file size is not always constant. In some cases, you might observe a smaller size for high resolution data, while the medium or low resolution data displays a higher number for the file size.

Terrain file location - defines the location and the name of the terrain file (3sm) to be created. This file can be reused to create different alternatives by attaching it to other dgndb files. Refer to the Attach section for more details.

Size - refers to the number of bytes (storage space) required to save a file on disk.

Image Size - refers to the dimensions of an image, the image's height and width. An image's screen size refers to how large it appears on a computer display, usually measured in pixels.

Image Resolution - is a measurement of the output quality of an image. Another way to think of it is as the density of an image. Resolution is usually referred to in terms of pixels for screen display.
