[OKGIS] NAIP Projections

[David W. Lowther]

Troy,

 

I wasn't offering - but that is a service that SCI has provided in the
past to our clients.

 

I was simply curious who uses this data in the projection it is
delivered and what was driving the projection choice (at any level:
federal, state, county, etc...) and if it made sense to consider looking
into having it created in a different format.

 

As far as the feds go - the National Map looks like geographic to me...
Isn't the NSDI, National Map, et all interested in this data (maybe not
at this scale)? My main gripe is that it isn't seamless for the state -
much less the nation.

David,

 

These photos were contracted for & paid for by the fed's. They like UTM.
The vendor could re-project them for us for little or no cost, but they
have been told that they can not as a condition of the contract (it
would be an unfair advantage over other vendors that could re-project
the data "after purchasing it" from the fed's).

 

Is SCI offering to re-project the entire state into Oklahoma planes
north & south (two pieces instead of three) and/or Oklahoma Albers (one
piece)? Is SCI going to use the uncompressed photos as source or
uncompress, re-project, and recompress the current sets? How much did it
cost the Conservation Commission when they re-projected the 1995's? 

 

Just asking.

	Has it occurred to anyone to question the logic that is relied
on to generate these images in UTM? 

	While it is certainly possible to extract and re-project the
images, it seems like a completely unnecessary step. Does anyone know
what drives the use of UTM? Anyone on this list prefer UTM to OK State
Plane or Albers?
