Welcome toT G I F
Tri-state GIS Integrative Forum
Fridays at NCAD 5:00 - 7:00pm -- 5 Fridays in March.
Open Discussions leading to Greater GIS coherence for Greater Cincinnati, USA!
In the United States, other than the Washington DC Metropolitan Statistical Area,
the Cincinnati MSA is the only major MSA including 3 states!
Further, within the Eastern US, comprising over 70% of our nation's population,
the Cincinnati MSA is central to all other Eastern North America major MSA's.
Please see the ArcGIS map document @ http://ncad.net/BSB_NA.pdf. (.5M)
In the map, the bold straight line, at meridian 100 degrees, spans from latitude 25 north to 50 degrees. It divides the US into Western and Eastern, across the sparsely populated plains. The orange circle around Paul Brown Stadium has radius 800 miles.
The projection is CONUS Equidistant Conic, centered at the Brent Spence Bridge.
MSAs are colored more deeply (US red, Canada green) as population increases, against a black background of states, enabling maximum contrast for each yellow dot which represents 1000 people, within a bounded place area (density plot). The transparency of each state is inversely proportional to its population.
An 800 mile radius around no other US city includes more people! Over 60% of the N.Am. pop!
Another interpretative map based on population data depicting a similar conclusion appears within a 2005 December article of GeoWorld.
GIS activity is rapidly increasing among two primary communities:
Of course, within each group, commonly, is a large contingent of its complement,
but, essentially, Providers produce highest accuracy data,
generally of interest to increasing numbers of GIS consumers,
who commonly pursue data from more than one Provider,
typically beginning with ESRI's readily available StreetMap® US Census TIGER data.
Builders/Providers generally align with standards within state or even county boundaries.
Consumers, especially in the tri-state, seek a unified regional GIS
covering two or three states, and many more counties.
Coordinate systems, schemas, and naming are common areas of noncongruence,
perturbing the consuming assemblers, who typically hold the keys to healthy metro growth.
Cincinnati, USA is the core of this tri-state region,
and must compete with other, nearby, regional MSAs,
that increasingly benefit from
while Cincinnati continues to struggle with its several disparate pieces.
Regional GIS coherence will lead to healthy, competitive,
What can we do to enable greater health for Greater Cincinnati, USA?
With obvious value to all regional issues:
Come enjoy healthy refreshment and discussion leading perhaps to a new regional strategy.
