Greetings all,

Not specifically a Mapinfo software question, but their may be a
Mapinfo based solution.

A quandry. How to conserve disk space (we are talking many many
gigabytes)?

I wish to store data in their observed geographical coordinates.

Many users require data in projected (calculated) coordinates to
enable area/distance calcs. We utilize a UTM projection for this and
unfortunately, our area of interest straddles a UTM Zone boundary.
Therefore this compounds the issue of diskspace, since if we wish to
access data as a seamless dataset, then we have to maintain a full
copy of data in both zones of two zones.

The ideal situation would be to maintain the one dataset in its
observed geographical coordinate system, and have a system in place to
provide users with data in whatever projection they require, live &
on-the-fly.

I understand tha some software packages can re-project on the fly, but
there would appear to be limitations when re-projecting larger
datasets.

An added complexity is that we also use imagery as a backdrop to
vectors, and this imagery cannot be reprojected.

How are other handling this?



Please respond directly to my email address as I have just joined this

I look forward to your responses.
