[Manifold-l] Manifold Release 8

[Pat Waggaman]

Michael,

Thanks for the response and apologies for the 
late reply, I´m moving about the Americas without Internet connections.

The objective here is cut Manifold calculation 
time or user latency by eliminating Lat Long 
projected layers in our webservers, Manifold 
speeds up considerably when all data are 
projected equally, and Mercator (in order to 
include readily available photo mapping) seems to 
be the way to go today.  Real time arriving data 
currently is in Lat Long and the balance of 
layers are in Mercator, saving the - currently 
Lat Long - incoming data in Mercator format speeds up the works.

The whole question may be moot - If the new MS 
SQL spatial db upgrade provides for the ability 
to rapidly project data on the fly, this may well 
eliminate the advantage of having all X(I) and 
Y(I) fields in a uniform projection.

Yes, in order to INSERT these points projected to 
Mercator into the MS SQL db, one-by-one in real time as the points come in.

Not a problem for current data that can be 
reprojected with the GUI with a LINK, PASTE AS a 
drawing, re-project the drawing and write the changes to the DB.
