<strong>Global</strong> <strong>Map</strong>per User's Manual<br />

♦ OPTIMIZED (BMP, ERDAS, GEOTIFF, and PNG only) - The palette generated will be an<br />

optimal mix of up to 256 colors that will closely represent the full blend of colors in the<br />

source images. This option will generate the best results, but can more than double the export<br />

time required if any high color images are present in the export set.<br />

♦ HALFTONE (BMP, ERDAS, GEOTIFF, and PNG only) - use a 256-color halftone palette<br />

spread over the color spectrum<br />

♦ DOQ_DRG (BMP, ERDAS, GEOTIFF, and PNG only) - use a 256-color palette optimized<br />

for combined grayscale DOQs and USGS DRGs<br />

♦ DRG (BMP, ERDAS, GEOTIFF, and PNG only) - use a 256-color palette optimized for the<br />

colors found in USGS DRGs<br />

♦ GRAYSCALE - use a 256-color grayscale palette<br />

♦ BW (BMP, GEOTIFF only) - creates a black and white, 1-bit per pixel image<br />

♦ BLACKISMIN (GEOTIFF only) - creates an 8-bit per pixel grayscale image with no color<br />

map stored in the image. Black will be stored as zero with varying shades of gray up to white<br />

with a value of 255.<br />

♦ WHITEISMIN (GEOTIFF only) - creates an 8-bit per pixel grayscale image with no color<br />

map stored in the image. White will be stored as zero with varying shades of gray up to black<br />

with a value of 255.<br />

♦ JPG (GEOTIFF only) - creates a 24-bit RGB JPG-in-TIFF image. Note that while this creates<br />

a highly compressed GeoTIFF file, many software packages do not recognize JPG-in-TIFF<br />

format files.<br />

♦ MULTIBAND (BIL, BIP. BSQ, GEOTIFF, and JPEG2000 only) - creates a multi-band image<br />

file with any number of bands of data. This is useful for multi-spectral imagery. Either 8- or<br />

16-bits per band will be used depending on what is available in the input data. Use the<br />

NUM_BANDS parameter to specify how many bands to use. You can override the default<br />

band setting using the BAND_EXPORT_SETUP parameter (described below).<br />

♦ Custom palette filename - you can also pass in the full path to a .pal file containing a custom<br />

palette to use for the export.<br />

• NUM_BANDS - specifies how many bands of data to export for a PALETTE=MULTIBAND export.<br />

If you don't specify a value for this the band count will be the maximum available for any of the<br />

loaded layers.<br />

• BAND_BIT_DEPTH - specifies how many bits to use for each band of data for a<br />

PALETTE=MULTIBAND export. If you don't specify a value for this the highest bit depth of any of<br />

the input data layers will be used. The valid values are BAND_BIT_DEPTH=8,<br />

BAND_BIT_DEPTH=16, or BAND_BIT_DEPTH=32.<br />

• BAND_EXPORT_SETUP - allows you to override the default band assignment for a MULTIBAND<br />

export. Use the following format to specify what band from what layer to use for a given export band:<br />

?? . So for example to assign the 4th (infrared) band in<br />

an export from the 1st (red) band in a previously loaded file name C:\data\input_file.tif, use the<br />

following parameter: BAND_EXPORT_SETUP="4?1?c:\data\input_file.tif". Note that you would<br />

include a separate BAND_EXPORT_SETUP parameter for each output band that you want to setup.<br />

If you leave off the filename then you all loaded data will be considered as input, with just the<br />

input-to-output band assignment being updated.<br />

• GRID_TYPE_CELL_SIZE - specifies that the export should be gridded into multiple tiles with each<br />

tile having the given size in the export projection. The value should be specified as cell width,cell<br />

height. For example, if you are exporting in a metric projection and want to tile the export into cells<br />

that are 10,000 meters wide by 5,000 meters tall, you would use<br />

GRID_TYPE_CELL_SIZE="10000.0,5000.0".<br />

• GRID_TYPE_PIXEL_SIZE - specifies that the export should be gridded into multiple tiles with each<br />

tile having the given size in pixels/samples. The value should be specified as cell pixel width,cell pixel<br />

height. For example, if you want to tile the export into cells that are 800 pixels wide by 600 meters<br />
