   Progress since Wall Summit „03

• Dramatic progress has been made!


• … but only because of the vital
  contributions from hard-working
  USGS staff dedicated to ………

What have we been using them for?

• Identifying Tree Voxels, bare earth vs.
  vegetation canopies
• Forest Fire Assessment
• Homeland Security / Urban Planning
• Demonstrations for funding solicitations
  • Translation: “The Data Pimp Must Eat”
• Portable Wall to be “stored” in Science

What are some of the problems                   5/10/2004 4:29:43 PM




in collating different datasets?
•   I say Elevation, you say topography
•   Stereo Pair Generation
•   Map Projection/Reprojection
•   General image processing of remote sensing data
•   Determining availability, and cost
•   Providing direct access
•   Interaction with data inside the Wall
•   Interactive retrieval of layers
•   Discussing high-rez imagery of our golf course
    instead of responding to the governor of SD

 How to solve visualizing large            5/10/2004 4:29:43 PM




          datasets?
• Money
• Hardware
  •   CPUs
  •   Graphics Cards
  •   Networking
  •   Sure, more faster memory
• But really the interactive loading of memory
  from remote data sources - Software
• Look-ahead pre-fetching

 How to get the data in the first           5/10/2004 4:29:43 PM




             place?
• Money
  • Build data costs into your grants
• If I get you something, share it with everyone
• Additions to seamless, and seamless-like
  clones
• Continued EDC improvement to distribution
  systems
• LDCM
• CRSP
• Better education by me of me

Mike Kelly‟s Suggested Questions from Wall Summit „03

Where are we getting our data now?
      Locations vs. disciplines?
Is Data Warehousing desirable for our developer community?
      What is meant by “Data Warehousing”?
      Is interactive access by visualization applications desired? Required?
      Metadata should include source and processing history?
Sharing our resources: The need for training/mentoring new developers?
      Hardware? Software? Data? Human?
What are the logical steps towards GIS?
      Are any of those steps occurring?
Wall Summit Attendee expectations:
      Where can I get every data set I saw this week? (and more, with desc.)
      How do I get my data to look like that?
      How do I get my OTHER data into multiple Viz App formats?
