calculation. You may select between the Clarke 1866 ellipsoid and the WGS84 ellipsoid.
New Zealand:
You may select between “NZGD2000” and “NZGD49”. Both use the Transverse Mercator
calculation. NZGD2000 uses the GRS80 ellipsoid. NZGD49 uses the International 1924 ellipsoid. You may
specify a Meridional Circuit with either datum. To select the circuit, press the Define button. You will see a
pull-down list with all Meridional Circuits as well as the option to pick None.
RGF 93 (France):
This system requires that you have the file named “Predef1.csl” in the SurvStar directory
on the data collector. If this file is not found, please re-install FAST Survey.
NTF (France):
This system requires that you have the file named “Predef1.csl” in the SurvStar directory on
the data collector. If this file is not found, please re-install FAST Survey. NTF is an approximation of the
NTF-GR3DF97A grid transformation.
NTF-GR3DF97A:
This system is a grid transformation that requires the files “Predef1.csl” and
“gr3df97a.bin” to be in the SurvStar directory on the data collector. The “Predef1.csl” file is part of the default
installation. You will need to use Data Transfer to copy the “gr3df97a.bin” file from your CD to your data
collector.
OSTN02 (UK):
This system is a grid transformation that requires the files “Predef1.csl”, “ostn02_x.bin” and
“ostn02_y.bin”. The “Predef1.csl” file is part of the default installation. You will need to use Data Transfer
to copy the “ostn02_x.bin” and “ostn02_y.bin” files from your CD to your data collector.
RD2000:
This is the RD NAP transformation for the Netherlands. This system is a grid transformation that
requires the file “Predef1.csl”, “X2C.grd” and “Y2C.grd”. The “Predef1.csl” file is part of the default
installation. You will need to use Data Transfer to copy the “X2C.grd” and “Y2C.grd” files from your CD to
your data collector.
Denmark 34:
Used for all cadastral mapping and for most technical mapping carried out in Denmark. System
34 is a two dimensional - horizontal - coordinate system. System 34 is based on the National Geodetic
Reference Network and is divided into two different zones, one covering Jutland and Fuen, and the other
covering Sealand. The island of Bornholm has its own coordinate system called System 45.
Add User Defined:
To define a new coordinate system, go to the Localization under the EQUIP tab. You will find
the Edit Projection List button under the SYSTEM tab. Then select the Add User Defined button. Enter a name
for your system (e.g. PRVI for Puerto Rico/Virgin Islands), then select a projection (in the example below,
Lambert_Conformal_Conic_2SP) and enter the appropriate parameters. Note that all latitude and longitude values
are in decimal degrees and False Northing and False Easting are always presented in meters. All entries involving
degree must be in decimal degrees based on a 360 circle.
New Datum:
You may select a predefined Ellipsoid or set your own parameters by typing in a new ellipsoid
name and entering values for a and 1/f. The values for dX, dY, dZ, rot X, rot Y, rot Z and scale are “to
WGS84”.
