Foreword

This standard is based on GB/T 1.1-2009 given rule drafting. This standard replaces GB/T 16831-1997 "Geographic position latitude, longitude and elevation of the standard notation", and this standard GB/T 16831-1997 compared to the main changes are as follows. --- Name change. "notation geographic position latitude, longitude and elevation of the standard" to "based on geographic location coordinates from the point Standard notation "; --- Added "Conformance" "3 Normative references" "4 Terms and Definitions" "5 Acronyms" "Geographical position 6.1 Conceptual Model" "Geographical position 6.2 Basic Element" "6.3 coordinate reference system ID" "coordinate resolution 6.6" "7.1UML model" "7.2XML Representation, "and Appendix A ~ C, Appendix E ~ G and so on; --- GB/T 16831-1997 Chapter 2 and Chapter 3 of this standard to 6.4, 6.5 and Appendix D, Appendix H, and other related content; --- GB/T 16831-1997 The term "elevation (altitude, in the present standard which is defined as an elevation)" describes the vertical position, the present Standard uses a more generalized term "elevation (height)", and allows the vertical position using the term "depth" to describe. This standard uses the translation method identical with the international standard ISO 6709.2008 "based on the geographic position coordinates of the standard notation."

Introduction

Located on the ground, air or underground geographic point location data for effective exchange need be widely interpreted and identified data format. This user in different disciplines may have different requirements. For example, when recording the longitude and latitude to take some degree and decimal degrees format Style, while others take the traditional degrees, minutes, and seconds; users may require different levels of precision, or use only the latitude and longitude instead Elevation. Use of this standard will be able to. a) reduce the cost of data exchange; b) by providing a standard interchange format prior knowledge, to reduce the time in preparation for the exchange due to the conversion of non-standard coding structure caused delay; c) provide flexible support for geographic point notation. Geographical position coordinates based on the standard notation

1 Scope

This standard applies to describe the geographical coordinates of the position switching point. This standard specifies the coordinate representation for data exchange, including latitude And longitude; also provides a location other than the level of geographic point latitude and longitude coordinate reference system used notation; also provides for the possibility of water Flat coordinates elevation and depth associated notation. Representation includes units of measure and coordinate order. This standard does not apply to computer memory during processing and measurement code parameter register information represents the earth. This standard is supported by Extensible Markup Language (XML) representation of the position, and allows the use of a single alphanumeric string to describe Said position. For computer data interchange of latitude and longitude, this standard recommends the use of general and decimal degrees; allowed six decimal notation Method. degrees, minutes and decimal minutes or degrees, minutes, seconds and decimal fractional seconds. The standard in the implementation process does not require special internal procedures, file organization techniques, storage media, and other programming languages.

2 Conformance

To be consistent with this standard, based on the coordinate position coordinate representation shall meet the abstract test suite (see Appendix A) all of the specified condition.
