Progress since Wall Summit ‘03

• Dramatic progress has been made!

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

Rob’s suggested questions to answer:What Data Sets are available?

What are up and coming?

What have we been using them for?

What are some of the problems in collating different datasets?

How to solve visualizing large datasets?

What Data Sets are available?

• Raw materials vs. Canned Demo Materials

• Raw Materials – Not just for Walls …• ASTER – 15m – free - downloadable

• Paul Morin

• MODIS - 250m – free - downloadable• http://edcdaac.usgs.gov/datapool/datapool.asp

• 133UA – 1’ – free – downloadable (or $500/250GB)• Seamless.usgs.gov – additional 30m layers

• Elevation – 10m/30m – free – downloadable• When USGS constructs something 3-D

of interest, I’ll post it

Soon to be Available?• Landsat 7 SLC-off or composites – GloVis.usgs.gov -

~200-300 $ per scene• LDCM – Goal is Launch within 5 yrs.• 133UA – 1’ – free – seamless• Lidar Elevation data - ~1m – free - seamless• DOQs – 1m – free – CONUS seamless• 3” aerial photography of GA location• IKONOS, QuickBird – 1-4m - Potential for

Declassification ; CRSP• Synthetic Aperture RADAR (SAR) – local library -

Mostly volcanoes• MRLC – 30m - $45 – local library – US only• Elevation – 10m/30m – free – downloadable – seamless

(NED) – continuously updated• Forest Fire growth model animations• Hurricane Flood inundation model animations• Higher-level geo-referenced data layers

Wall Summit ‘04

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 Department’s Lab – stay tuned

Wall Summit ‘04

What are some of the problems 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

Wall Summit ‘04

How to solve visualizing large 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

Wall Summit ‘04

How to get the data in the first 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

Wall Summit ‘04

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?

Where Are We Getting Data Now? (Summit ’03)

Provider Perspective

• USGS• Satellite Images +

Elevation• LIDAR• Aerial

• Scripps• ESA, USGS, Seismology

• UMN• ……

• UMI• ….

• ASU• ……..

• EVL• …….

• Everyone Else?

Consumer Perspective

• GeoWall.org• Anywhere else?

(at least for purpose of sharing/distributing)
