is
a
partnership
among
US
EPA,
States
and
Tribal
partners
to
promote
the
efficient

through
the
development
and

Foreword
The
Environmental
Data
Standards
Council
(
EDSC)
identifies,
prioritizes,
and
pursues
the
creation
of
data
standards
for
those
areas
where
information
exchange
standards
will
provide
the
most
value
in
achieving
environmental
results.
The
Council
involves
Tribes
and
Tribal
Nations,
state
and
federal
agencies
in
the
development
of
the
standards
and
then
provides
the
draft
materials
for
general
review.
Business
groups,
non­
governmental
organizations,
and
other
interested
parties
may
then
provide
input
and
comment
for
Council
consideration
and
standard
finalization.
Draft
and
final
standards
are

INTRODUCTION
The
Latitude/
Longitude
Data
Standard
is
a
set
of
data
elements
that
can
be
used
for
recording
horizontal
and
vertical
coordinates
and
associated
metadata
that
define
a
point
on
the
earth.
The
latitude/
longitude
data
standard
establishes
the
requirements
for
documenting
latitude
and
longitude
coordinates
and
related
method,
accuracy,
and
description
data
for
places
of
interest
to
the
Environmental
Protection
Agency
(
EPA).
Places
include
facilities,
sites,
monitoring
stations,
observation
points,
and
other
features
regulated
or
tracked
under
Federal
environmental
programs
within
the
jurisdiction
of
the
EPA.

1.1
Scope
The
purpose
of
the
standard
is
to
provide
a
common
set
of
data
elements
to
specify
a
point
by
latitude/
longitude.
This
standard
describes
data
elements
and
data
groupings
that
are
used
to
exchange
Latitude/
Longitude
data
and
information.

1.2
References
to
other
data
standards
This
standard
relies
on
two
other
standards
to
make
it
complete
and
provide
the
necessary
support.
As
such,
users
should
reference
the
normative
standards
listed
below
and
consider
them
integral
to
the
Latitude/
Longitude
Standard.
These

Users
are
encouraged
to

housed
on
the

Web
site
to

Based
on
the
