  • We are really good at sharing data. Cities, counties, state, federal, private sector and non-profit agencies cooperatively share.
  • Publish to all major internet sources. These touch the 99% that might not otherwise see this data.

    • Established in 2003
    • Coordinate with all levels of government, non-profit and the private sector
    • Support GIS data development and distribution via GeoStor in an effort to reduce duplication
    Create Once,
    Share it a Bunch
  • 3
    Over 200 Datasets
  • All the distribution Mechanisms
    • Download: zip, clip, ship in multiple formats and projections
    • FTP
    • Web Services
    • Also push data to a number of entities
  • Arkansas GIS Data
    “Accessed Globally”
    Unique Visitors to GeoStor by Country
    We are globally searched and good at what we do.

    business decisions and
    economic development.

    Tell you why on the “Ubiquitous slide”
  • @CrisisMappers - Sometimes the questions are complicated
    and the answers are simple. ~Dr. Seuss
    Question: Why should government provide open data?
    Answer: It’s the right thing to do.
    Answer: It’s been paid for with tax-
    payer dollars.
    Answer: arrrrrrrh!!!!
  • Why Publish? Economic Dev
    Mitsubishi doesn’t make a$100M investment without looking at a bunch of maps
    “Current GIS information provides Arkansas with a strategic advantage in economic development.“
    -Senator Shane Broadway

    Why Publish?A picture is worth a 1,000 words
    2010 Google- Imagery 2010 DigitalGlobe, Pulaski Area GIS, State of Arkansas, GeoEye, US Geological Survey
  • Why Publish? Disaster will strike
    December 16, 1811, 0815 UTC (2:15 a.m.); (M ~7.2 - 8.1) epicenter in northeast AR.
    December 16, 1811, 1415 UTC (8:15 a.m.); (M ~7.2 - 8.1) epicenter in northeast AR.
    January 23, 1812, 1500 UTC (9 a.m.); (M ~7.0 - 7.8) epicenter in the Missouri Bootheel.
    February 7, 1812, 0945 UTC (4:45 a.m.); (M ~7.4 - 8.0) epicenter near New Madrid, MO.
    Some sections of the Mississippi River appeared to run backward for a short time.
    Sand blows were common throughout the area, and can still be seen from the air in
    cultivated fields. The shockwaves propagated efficiently through midwestern bedrock.
    Residents as far away as Pittsburgh and Norfolk were awakened by intense shaking.
    Church bells were reported to ring as far as Boston, Massachusetts and 
    York, Ontario (now Toronto) and sidewalks were reported to have been cracked and broken
    in Washington, D.C. There were also reports of toppled chimneys in Maine.
  • Why Publish? Disaster will strike
    Eliza Bryan in New Madrid, Territory of Missouri, wrote the following eyewitness account in March, 1812.
    “On the 16th of December, 1811, about two o'clock, A.M., we were visited by a violent shock of an earthquake, accompanied by a very awful noise resembling loud but distant thunder, but more hoarse and vibrating, which was followed in a few minutes by the complete saturation of the atmosphere, with sulphurious vapor, causing total darkness. The screams of the affrighted inhabitants running to and fro, not knowing where to go, or what to do - the cries of the fowls and beasts of every species - the cracking of trees falling, and the roaring of the Mississippi - the current of which was retrograde for a few minutes, owing as is supposed, to an irruption in its bed -- formed a scene truly horrible.”
  • Who contributed
    County filesGood for geocoding
  • Mission Accomplished
  • Mission Accomplished The work continues
    More Inputs will result
    In better data
  • Why Publish? Ubiquitous use
    We touch .1% of N and that’s generous. Our desire is to have high quality ARGIS data used by everyone that makes decisions. This means we need helpreaching the other .99% of N.
    Good at pushing out!!!Need Feedback LoopFlagging System
    Knowing about user changes ineach system would make for better data.

    • Better Data
    • How do we load good data into OSM for the state of Arkansas?
    • Not alienate current contributors?
    • Publish (flag) changes from each system?
  • 1. We are interested in helping make OSM better, but don’t want to mess it up.2. We also want to work toward a sustainable solution that can be integrate within our workflow.
