CreateSubdivideMrSidImageryProgramNode

This command creates a SubdivideMrSidImageryProgram node in the hierarchy. A program node is similar to a dialog-based wizard except the wizard is stored in the scene graph. This program subdivides an entire MrSid file and outputs high-resolution and low-resolution GEOTIFF tiles suitable for use with Scenome. Typically this program produces hundreds or thousands of output GEOTIFF tiles from a set of MrSid files.

Figures

This command creates a SubdivideMrSidImageryProgram node in the hierarchy. This node stores information used to extract GEOTIFF imagery from a set of MrSid files.

Figure 1.2. A list of files on the hard disk. The SubdivideMrSidImageryProgram generates from the input the output as shown. The high_resolution GEOTIFF tiles are a full-resolution 4×4 subdivision of the MrSid file. The low_resolution GEOTIFF tiles are also from the 4×4 subdivision but the tiles have been resampled to 128×128 pixels. The SubdivideMrSidImageryProgram node performs all the subdivision, renaming, resampling, and copying of GEOTIFF tiles.
