Use Last Exported Sample Spacing will update the X and Y values to the most recent export resolution. The Use Current Screen Pixel Size button will update the X and Y values to the dimensions of the map display. These pixel dimensions will be translated into the units of the display projection during export. Specify the X and Y spacing of the output pixels in any of the selected units. To specify the spacing in units other than those of the currently selected view/ export projection, press the Click Here to Calculate Spacing in Other Units button. Selecting Always Generate Square Pixels ensures that the resultant image file will look good even in software that is not able to deal with pixels that aren't square. If the Always Generate Square Pixels option is checked, the smaller of the specified x and y resolutions will be used for both the x and y resolution. The default value is the average of the grid spacings of all the currently loaded raster and elevation overlays. The Sample Spacing section allows the user to select the grid spacing to use when generating the file. When converting from an existing palette image, the new image will be assigned the palette index (PAX IDX) of the closest matching RGB value in the new palette. The following choices of palette are available: Indicating what 256 colors will be used to describe the image being exported. Samples will be stored as 32-bit floating point values.Ī 256 color (8-bits per pixel), it is necessary to select a palette Grid using the currently loaded elevation grid data sets. (32-bit floating point samples) - This option generates an elevation Check that vertical units are appropriate prior to using this option, intended for use with high resolution, sub-metric elevation data and values. Will be stored as signed 32-bit integers. (32-bit integer samples) - This option generates an elevation grid Will be stored as signed 16-bit integers. Using the currently loaded elevation grid data sets. (16-bit integer samples) - This option generates an elevation grid This can be reversed by selecting the Grayscale By default, white will be a value of 0 and black will beĪ value of 1. Source image had more than two colors the resulting image will be This will generate the smallest image of these options. Input sources for each band in the output image.Īnd White - This option generates a two color file with 1 bit After selecting this option additional dialogs will be presentedĪllowing for further setup of the multi-band export by choosing the Than 3 bands of data, such as RGBI, Landsat imagery, or data sets with Is very useful when working with multi-spectral imagery with more Of data at either 8-, 16-, or 32-bits per band of data. This option generates a raster file with 1 or more bands Some compression using compression option. You can also maintain the colors while achieving Option, but the colors in the image will exactly match what you see Uncompressed images generated with this option willīe at least 3 times the size of those generated with the 8-bit Palette RGB - This option generates a raster with 24-bits per The Palette options described below will apply Palette Image - This option generates a 256-color raster file The various file types are described below: Type section allows you to choose what type of file to generate.
