Set options for the output image in the Output tab. The options that you see depend on the job type and the output format.
You can specify the following options:
For raster images, you can create test images to test an image manipulation or compression operation without using data from the data cartridge. Test images are output images that have a visible watermark. You can create images and mosaics as test images, but not LiDAR point clouds.
Converting unsigned 16-bit data to unsigned 8-bit data during encoding.
You can add custom watermarks to your images. GeoExpress supports black and white watermark images in BMP, PNG, and JPEG formats.
Click the Browse button to select the image that you want to use as a watermark. The following figure shows an example of a watermarked image:
NOTE: In versions of GeoExpress before v9.5.3, watermark images were limited to 128 × 128 pixels in size. Watermarks must be no wider and no taller than the output image.
You can choose to generate a shapefile that shows the tiles that make up a raster mosaic output.
If you create a raster mosaic, select this option to include a shapefile in the output. When viewed with the appropriate program (such as GeoViewer), the shapefile will overlay the output image to indicate where each tile in the image is located.
If the job contains DOQ images, the USGS DOQ Cropping panel will be available. Cropping is either by corner cross or disabled.
To flatten a composite mosaic, select the Create Flattened Mosaic option. When you flatten a mosaic that contains overlapping tiles, you discard the data from tiles that are not visible. For more information on composite mosaics, see Mosaic Output Formats.
When you flatten a mosaic, the Flatten Tile Size field is available. GeoExpress divides mosaics that are to be flattened into tiles for encoding. Acceptable values are integers between 1024 and 4096, and powers of two (1024, 2048 and 4096) are recommended though not required. The default tile size is 2048.
NOTE: You may encounter irregularities in the progress meter when flattening mosaics.
