Dear Colleagues,
The University of Wisconsin-Madison Space Science and Engineering Center (SSEC) has prepared a software package as part of the NASA International MODIS/AIRS Processing Package (IMAPP) that enables users to display satellite imagery in a Google Maps or Google Earth interface. It is distributed as an 8 GB virtual machine (VM) that is capable of displaying MODIS (and VIIRS) GeoTIFF images created from the IMAPP/CSPP Polar2grid software package in support of Direct Broadcast users. IMAPP RealEarth is a browser-based GeoTIFF imagery viewer powered by SSEC’s RealEarth Web Mapping System. IMAPP RealEarth allows users to process imagery generated by their IMAPP installation for display in Google Maps, and share that imagery with users through a web mapping service.
The following define the host system requirements. Please note: Your system will not be able to support the IMAPP RealEarth Virtual Machine (VM) unless it meets all of these requirements:
- Intel or AMD CPU with 64-bit instruction support
- RedHat or CentOS Linux v.6 host server
- Root privileges on host server
- Hardware virtualization enabled in the host system BIOS
The web interface allows users to select from preset Aqua and Terra MODIS band swath or composite displays. The choice of spectral bands and how they are displayed is configurable. Users can add their own (non Polar2grid) GeoTIFF files if desired. Users also have the capability to share their display with colleagues and export it to Google Earth.
The IMAPP RealEarth installation and execution instructions are available through the IMAPP website:

The IMAPP/CSPP Polar2Grid software is a package for reprojecting MODIS Level-1B (L1B) files and VIIRS Science Data Records (SDRs) files into GeoTIFF format. It is freely distributed through this website:

Kathy (for the IMAPP RealEarth Team)
