Hi all,
This is more a cartography question than a PostGIS question, but this
seems like the right list to ask on. I've got parcel data from several
counties that are in US state plane feet projections and I want to
create address points that are in NAD83 geographic coordinates. There
are three possible answers about how to proceed: (A) get the centroids
from the US state plane feet parcels, and then re-project the centroids
to NAD83 geographic cooridnatesa; (B) re-project the parcels to the
NAD83 geographic projection and then get the centroids of the
re-projected parcels; or (C) pick one since the locational differences
between the two approaches will amount to rounding error. My best guess
is that (C) is the correct answer, but I want to use the approach in (A)
for reasons of computational efficiency.
