Enhancements to this SPA include:
The BlueMarble SPA can create MODIS sharpened True Color and Natural Color imagery; VIIRS sharpened True Color and Natural Color imagery; VIIRS Enhanced Near Constant Contrast (ENCC) day and night imagery; and overlays of OMPS SO2 and OMPS Ultraviolet Aerosol on VIIRS True Color. The package also allows overlays of fire location pixels and shapefiles on these image products. The True Color, Natural Color and ENCC image products can be used in various Earth science disciplines to visualize Earth features, track environmental phenomena, and as background images to provide more context to other Earth science data overlaid on them (such as the OMPS overlays on VIIRS True Color images available in this package). The SPA functions in two modes: Standalone, or as an IPOPP plug-in (IPOPP v2.6 required). Please refer to User's Guide for a detailed list of features and capabilities.
Installing as a Standalone Application:
Download the BLUEMARBLE_2.2_SPA_2.2.tar.gz and BLUEMARBLE_2.2_SPA_2.2_testdata.tar.gz (optional) files into the same directory.
Decompress and un-archive the BLUEMARBLE_2.2_SPA_2.2.tar.gz and BLUEMARBLE_2.2_SPA_2.2_testdata.tar.gz (optional) files:
$ tar -xzf BLUEMARBLE_2.2_SPA_2.2.tar.gz
$ tar -xzf BLUEMARBLE_2.2_SPA_2.2_testdata.tar.gz
See the User's Guide (PDF) included with the software package for more details.
Installing into an IPOPP Framework:
This SPA can also be installed dynamically into an IPOPP framework to automate production of BlueMarble data products. The SPA installation process will install SPA service(s) into IPOPP. An SPA service is an IPOPP agent that provides the mechanism necessary for running an SPA automatically within the IPOPP framework. Once this SPA is installed, users must enable the service(s) corresponding to the SPA. Instructions for installing an SPA and enabling its services are contained in the IPOPP User’s Guide (available on the DRL Web Portal). The SPA stations for this SPA are listed in Appendix A of the User's Guide (PDF) included with this software package.
In order to run the package using your own input data, you can either use the run scripts within the wrapper subdirectories, or modify the test scripts within the testscripts subdirectory. See the User's Guide (PDF) included with the software package for more details.
