Global Swath and Gridded Data Tiling
- Created on Monday, 01 October 2012
This software generates cylindrically projected tiles of swath-based or gridded satellite data for the purpose of dynamically generating high-resolution global images covering various time periods, scaling ranges, and colors called “tiles.” It reconstructs a global image given a set of tiles covering a particular time range, scaling values, and a color table. The program is configurable in terms of tile size, spatial resolution, format of input data, location of input data (local or distributed), number of processes run in parallel, and data conditioning.This software can dynamically generate global images of various temporal and spatial resolutions without having to go back to the original data files, reading and conditioning, and re-projecting the source values. It can be utilized to efficiently generate global imagery of various temporal and spatial resolutions based upon cylindrically projected tiles that have been created from swath and gridded data sets.
The package supports JPL’s Physical Oceanography Distributed Active Archive Center’s (PO.DAAC) State of the Ocean Web page (http://podaac.jpl.nasa.gov/ soto), a Google Earth-based Web interactive visualization tool.
