|
Use of the Data
|
|
|
|
The user assumes the entire risk as to the accuracy and the use of
|
|
this data. The data may be used, copied and distributed subject to the
|
|
following conditions
|
|
|
|
1. INFORMATION PROVIDED IN THIS DOCUMENT IS PROVIDED "AS IS" WITHOUT
|
|
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING BUT NOT
|
|
LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND/OR FITNESS
|
|
FOR A PARTICULAR PURPOSE.
|
|
|
|
2. The data may be included in any commercial package provided that
|
|
any commerciality is based on value added by the provider and not on a
|
|
value ascribed to the EPSG dataset which is made available at no
|
|
charge. The ownership of the EPSG dataset [OGP] must be acknowledged.
|
|
|
|
3. Subsets of information may be extracted from the dataset. Users are
|
|
advised that coordinate reference system and coordinate transformation
|
|
descriptions are incomplete unless all elements detailed as essential
|
|
in OGP Surveying and Positioning Guidance Note 7-1 annex F are
|
|
included.
|
|
|
|
4. Essental elements should preferably be reproduced as described in
|
|
the dataset. Modification of parameter values is permitted as
|
|
described in the table below [*] to allow change to the content of the
|
|
information provided that numeric equivalence is achieved. Numeric
|
|
equivalence refers to the results of geodetic calculations in which
|
|
the parameters are used, for example (i) conversion of ellipsoid
|
|
defining parameters, or (ii) conversion of parameters between one and
|
|
two standard parallel projection methods, or (iii) conversion of
|
|
parameters between 7-parameter geocentric transformation methods.
|
|
|
|
5. No data that has been modified other than as permitted in these
|
|
terms and conditions shall be described as or attributed to the EPSG
|
|
dataset
