Coordinate Systems

With all of these movements in coordinates, how is a surveyor

expected to maintain a coordinate database that can be

used for years? Javad’s knowledgeable team of geodesists

and software engineers has created a rigorous and accurate

means to accomplish this. Because NAD83 is constantly

maintained by NGS relative to IGS08 (which is substantially

the same as ITRF2008) through observed velocities of the

Continuously Operating Reference Station Network (CORS),

it is possible to relate the internal coordinate database to a

specific epoch (date and time) within ITRF2008. For J-Field

the internal reference frame and epoch is ITRF2008, at the

epoch (or date/time) defined by the user at the creation of

a particular Coordinate System. As Coordinate Systems are

refined creating new adjustments, this scheme will allow any

collected points to be easily transformed across epochs and

reference frames to other highly precise reference frames

both now and in the future. For the surveyor, all of this is

transparent and he may well never view his coordinates

related to ITRF2008 in J-Field, preferring to only consider

his coordinates in his favorite geodetic coordinate system,

but he will do well to understand that internally within the

database all coordinates in all projects are related to the

same reference frame with the appropriate epoch.

Therefore if a surveyor enters the NAD83(2011) coordinates

of a point from an NGS Online Positioning User Service (OPUS)

solution into J-Field, with the proper coordinate system set,

the coordinates are transformed from NAD83>ITRF08 using

a 14 parameter transformation and then stored. At any time

these coordinates are viewed, exported or used for COGO

calculations, they are retrieved from the database as ITRF08

and transformed from ITRF08>NAD83 before being used or

displayed.

Beyond the benefits of storing all project coordinates in a

common reference frame, users can also make use of the

ITRF08>NAD83 transformations for entering coordinates

from positioning services that do not support NAD83, such

as the Australian Positioning Service (AUSPOS). Because this

service only publishes ITRF08 coordinates, it is necessary to

make the transformation from ITRF08>NAD83 if the user

wishes to be related to NAD83.

J-Field

can accomplish this

with ease.

Building A Coordinate

System In J-Field

In J-Field, a Coordinate System is composed of:

A Related Geodetic System (or reference frame) such

as WGS84(ITRF2008), PZ-90 or NAD83(2011)

A predefined Projection, such as UTM or State Plane

or any other custom Projection including Transverse

Mercator, Lambert Conformal Conic 2SP/1SP, Cassini-

Soldner, Transverse Mercator, Oblique Mercator

(Hotine Variant A and B), Oblique Mercator (2 Points),

Oblique Stereographic, Mercator, Polar Stereographic

(Variant A and B). LLH and ECEF can be used without

a projection if desired.

A Height System (Ellipsoid or Orthometric)

A Geoid if the Height System is Orthometric - Geoid

models approximate sea level, as affected by

variations in gravity, which is necessary for precise

GNSS positioning to make meaningful heights

consistent with the results of a level run

An Epoch, a point in time to which the composed

coordinates will be related

A Transformation, 14 parameter transformation

used to convert the user’s coordinate system to

WGS84(ITRF2008) or a time-related transformation

such as HTDP in U.S. and the National Epoch
