Hardware Opportunity

Two uses of OAM

  • Store and serve tiles
  • Storage of raw imagery

Debate over Operating System: Solaris or Linux distro

  • Solaris: provides ZFS which can support billions of files and easy to scale storage. Reduces the number of people who contribute to administration of the system.
  • Linux: easier to develop on and admister, but has file system issues (corruption) with large numbers of files.

Next Steps

Hardware

  • 1 Week: Have a Linux box up for development
  • 1 Month: attach a Solaris ZFS storage server. No one will have administration rights to this storage outside NPS, with aid/advice from Jeff and Travis.

Software

Initial Data Sets For now, we will focus on quality, georectified imagery. We will look at kites and hobbyist imagery in the future. We will serve a developer community that wishes to use tiles in their applications. We have to document provenance of data, and our documentation has to be provable against a challenge.

  • Landsat Imagery
  • NAIP Imagery. Public Domain. The cost (cost recovery issues) are being investigated.
  • Legal advice on how to make the data policy bulletproof.

Opportunities to Learn

  • NPS will abide by decisions of the group. Only veto power is the information security team at NPS, which can pull the plug.
  • DISA has standards for OpenSolaris. Travis had to handle this issue, Don McGregor is now facing it.
  • Ask Sun Microsystems/Oracle about building out a network of OpenSolaris experts who can help with configuration and architecture.
