Hi,
Hopefully a simple question, but if you were building something
completely new, how would you record the data? Specifically if you
wanted to use OSM, would you store the co-ordinates in EPSG:3857 or
EPSG:4326? Of course if you need to exchange data with other systems
EPSD:4326 might be more useful as users are fairly familiar with the
idea of latitude/longitude, however given this would be the exception
rather than the rule, is there any merit in storing the data in
EPSG:3857 and converting to EPSG:4326 when needed? Would this be any
faster with less conversions going on to plot the data on a map? If this
is sensible is there an easy way to convert EPSG:3857 to tile names like
there is for EPSG:4326?
Your thoughts are appreciated.
Thanks
Scott
