This presentation provides an introduction and walk-through of the LoCloud Geocoding application, used during the LoCloud training workshops. The application is a tool to add geographic coordinates to existing data (such as records describing items of content in digital libraries). The presentation includes a step-by-step walk through of the application

31. • Star'ng
with
X
million
non-­‐geo
records
is
difficult
– Will
take
a
long
'me
to
reach
interes'ng
sample
size.
– Easier
to
get
help
to
improve
than
create
from
scratch
• Solu'on:
combine
automa'c
and
manual
approach
• First
auto-­‐enrich
using
available
tools
– List

32. LoCloud
Geocoding
Tool
for
Desktop
Involves
poten'ally
hundreds
of
database
lookups
per
geocoded

Best
suitable
for

not

shared

Adapted
to
specific
na'onal
datasets
–
key
registries
include:
• Property
• Address
• Persons
• Named
en''tes
At
the
outset
adapted
for
Norwegian
registries
but
can
easily
be
adapted
to
any
other
European/na'onal
key
registry
