Introduction

Welcome to the "1.2" release of libkml!

It is the intention of libkml to adhere strictly to the OGC KML 2.2 standard.

What is libkml?

This is a library to parse, serialize and programmatically access a KML document object model (DOM). The main API is C++, and there are SWIG bindings to Python and Java.

Who uses libkml?

We do! Here at Google we regularly process the millions of KML files we crawl using this software. We verify correctness of the KML we publish as Google Earth layers using libkml. Quite a number of groups within Google use libkml to parse, create and process KML.

Licensing

The libkml software is distributed under the New BSD license, whose text is found at the top of each file.

Supported platforms

This library has been compiled and tested on Windows XP, Mac OS X 10.4 and 10.5, and various flavors of Linux.

Changes since 1.1

• Upgraded third-party UriParser library to latest version
• Replaced use of std::string with string to permit direct use in codebases that have their own (STL-compatible) string implementation
• Replaced use of char* and XML_Char* with string in the low-level wrapper around Expat
• Improved Google Maps and Spreadsheets Data API support
• Added some support and example programs for CSV files in the Google Maps DATA API
• Added a callback to the regionator code to allow progress monitoring, cancellation
• Added option for quadtree-aligned regionation
• Fixed a spec issue with LatLonBox defaults (now +/- 180, not 0)
• Smarter serialization of potentially bad CDATA text
• Windows build fixes
• A new static lib target in the XCode project
• Restricted the maximum element nesting depth in XML parsing to 100 (can be overridden at compile time)
